Making Cat Food

With bones or without bones; how much bone
Making the food - VIDEO
I frequently see people jump into making cat food without doing their homework and without any thought as to using a balanced recipe. This is what gives veterinarians - including myself - a very good reason for recommending against homemade diets.
I recently came across a post within an internet group stating how "wonderful" my Making Cat Food page is - including the recipe provided below. However, the poster then went on to outline what she was feeding to her cat which was not even close to the recipe discussed on this webpage! This poor cat was being fed a terribly UNbalanced diet because his owner was using her own 'creation' based very loosely on the recipe below.
She had completely missed the boat on this very critical issue and was harming her cat.
If you are not going to follow a balanced recipe, then please feed a balanced, commercial canned food diet. Please see Feeding Your Cat: Know the Basics of Feline Nutrition for reasons why dry food is not a healthy diet for any cat.
Making cat food: Do it and do it right, or don't do it at all. It is not difficult to make cat food but do your homework first and do not get 'creative' and start adding/omitting ingredients to/from a balanced recipe.
After spending a great deal of time reading and learning about the way commercial pet foods are processed, and the ingredients that go into many of these foods, I decided to start making my own cat food. I found that I was getting more and more frustrated with the species-inappropriate and low quality ingredients found in most commercial foods so this was a very easy decision for me to make.
Also, the 2007 Menu pet food tragedy that resulted in the deaths and severely compromised health of many cats and dogs left me with an even deeper desire to have as much control as possible over what goes into my cats' food bowls. I don't ever want to go through what those people went through when they lost their beloved pets due to human greed and deception. I remember feeling a great sense of relief knowing that my cats were eating a diet that I had personally sourced and prepared for them - and that feeling continues. I don't see myself ever going back to feeding commercial cat food.
My cats are very special to me and I feel it is important for them to eat a diet that is equal in nutritional quality to what I would put on my own dinner plate. I spend a few hours in the kitchen every ~8 weeks making a batch of food that is then frozen. This is a small amount of time out of my schedule given the rewards.
I have been using the recipe below since early 2003 and I could not be happier with my cats' health and energy level and - again - my control over their diet.
If you decide that making cat food is not for you, then please at least feed canned food and no dry food.
This subject is one of considerable debate among two - usually strongly divided - mindsets.
The anti-raw folks are afraid of bacteria and parasites.
The pro-raw feeders are afraid of nutrient loss from cooking/processing.
However, it is not necessary to have such an 'all or nothing' viewpoint and our cats will benefit if people approach this issue with more critical thought and compromise.
Unfortunately, often neither group considers how the meat is sourced and fail to see that one can strike a balance between the two issues.
Our goal is to feed a diet that nature intended for our carnivores - staying as close as possible to the form and nutritional composition that our cats would eat in a natural setting - while implementing safety strategies as discussed below.
I am not as smart as nature. No human is - even board-certified veterinary nutritionists. None of us know exactly what nutrients and in what amounts are destroyed/damaged with the cooking process.
Because of this fact, I choose to 'split the difference' between semi-cooked and 100% raw depending on the source of the meat.
I feed meat from two sources:
With regard to parasites, commercially raised meat (either from the grocery store or producer) is much less apt to be infected with parasites when compared to wild game.
However, meat from a grocery store can be higher in bacteria than meat from a fresh kill in the wild or meat purchased directly from the producer.
But having said that, when considering the issue of bacteria, I am reminded of the mountain lion that ate off of a deer carcass in my brother's backyard for one week in northern California (not a very cold location...therefore, more bacterial growth). The mountain lion was dining on meat that was a week old in the ambient temperature (not refrigerated) and did just fine.
For the first ~7 years of feeding a homemade diet, I purchased chicken or turkey thighs and simply rinsed them very well with water before grinding them. However, I have since decided to increase the safety of the diet and I now partially baking whole thighs to kill the surface bacteria.
This partial baking makes the diet much safer than dry food.
The main reasons for the switch were:
The chicken or turkey (thighs) cat food that I make usually ends up being ~25 - 50% cooked and ~50 - 75% raw but you should aim for at least a 10-20% surface cook.
The rabbit that I source directly from the producer is fed raw because it is frozen as soon as it is processed and arrives on my doorstep frozen. It is never in a refrigerated state. Refrigeration slows bacterial growth but does not halt it.
For more details, please see my safety section below.
It is up to the reader to work within their comfort zone when deciding whether to go forward with this type of diet, or not. Most things in life do have some risk associated with them but most people think that commercial diets are completely without risk and this could not be further from the truth.
With the critical thought that I put into my cats' diet with regard to sourcing and preparation, I would confidently submit their diet to a 'safety contest' with any dry food on the market.
Dry food (aka "kibble"), in addition to containing potentially deadly fungal toxins, contains a great deal of bacteria.
If you would like to read more comments regarding pet food recalls and the issues with commercial pet food contamination - especially dry food - see below.
Fortunately, our cats' intestinal tract is designed to handle a much higher bacteria load than that of a human, but if one is worried about the bacteria in raw meat, then the bacteria in dry food also needs to be taken into consideration because dry food is very far from bacteria-free.
(Figures were last updated December, 2010)
A reader of this webpage contacted me regarding a coupon program at iherb.com that allows for $5 off your first purchase if you enter the following code: LIS675 or just click on this link which will take you to the main webpage where the discount will be automatically applied.
iherb.com is the company that I order my supplements from when I don't have the time to buy them locally.
See the Recipe section below for links to specific ingredients that I order from iherb.com.
Also note that a recent (February, 2012) thread on the Feline Diabetes Message Board involved several members discussing their cost savings when comparing the diet on this site with commercial canned food - with Fancy Feast being a comparative price point.
The cost varies with what type of meat you feed and the source, and also the cost (usually minimal) of your supplements. The initial expense of the supplements may seem high but they last a long time and really do not add much to the cost.
The following figures are my approximate costs. They include a very rough guesstimation of 24 cents/pound of finished food for supplements.
As noted above, I feed meat from two different sources:
I buy free-range (whatever that really means given that this issue is poorly regulated), antibiotic- and hormone-free chicken thighs (with skin and bone) from Whole Foods Market for $1.99/lb or I buy turkey thighs for $2.99/lb. Some cats like turkey better than chicken. Turkey seems to have a stronger smell than chicken which entices some cats.
As much as I would love to buy organic, it is just too expensive.
When factoring in the added water, eggs, and the supplements, it works out to be ~$2.00/lb of finished chicken food and ~$2.77/lb of turkey food. My cats eat about 5 - 6 ounces/day so this diet costs ~$0.63 - $0.87/day/cat when figured on 5 ounces/day/cat.
Depending on the source, Wellness canned cat food works out to be ~$5.19/lb if purchasing the 5.5 ounce cans and ~$3.57/lb if using the more economical 12.5 ounce cans. (These prices reflect our local 9.75% tax but the base prices were obtained from Amazon.)
As you can see, I am able to make a nutritious chicken or turkey diet for much less than a high quality canned food such as Wellness - and I have more control over the ingredients and composition. (Composition = percentage of calories from protein, fat, and carbohydrate)
Many people get poultry thighs from places like Costco which will be cheaper than Whole Foods Market but I am not sure where these discount stores source their meat and if it possible to get antibiotic and hormone-free meats from these stores. But that said, I would still rather make a homemade diet from these meat sources than to feed any commercial food.
The second type of meat that I feed is rabbit and it is shipped to me from Washington - wholefoods4pets.com. I buy 52 lbs at a time of the Extra Fine Double Ground (the most expensive choice) in the 4 lbs packages which net out to $4.45/lb. When shipping is figured in ($56.90 for the 52 lbs - November, 2010), it comes to $5.54/lb. When the supplements and water are added, the finished food is $4.77/lb - still cheaper than 5.5 ounce cans of Wellness but much more expensive than cheaper canned foods or homemade chicken food.
I purchase the Extra Fine Double Ground because my cats were having problems with the bones in the more coarsely ground product in that they would paw violently at their mouths as if a bone got stuck in their gum tissue.
Another option is to buy the less expensive course ground and re-grind it yourself using the 4 mm plate that I show under the Safety section below.
July 2012 update
For the past 9.5 years, I have used a
meat grinder (a #12 grinder) but it finally died
after years of faithful service grinding
approximately 45 lbs of meat and bones each
month. What a truly impressive workhorse it
has been! I never expected it to last this
long given the amount that I grind. I am
debating whether to give it a proper burial
or send it to
One Stop Jerky Shop to be repaired.
I have such a soft spot in my heart for this
grinder that I will most likely get it
repaired so that I can have it as a back-up
Anne (catnutrition.org ) has been using hers for ~11 years to make food for 2 cats. However, if you are interested in a faster and quieter grinder, I suggest that you consider the Weston #12. Honestly, I am kicking myself for not upgrading sooner.
If you are
interested in the smaller Weston #8,
understand that it has a smaller feed tube
and it is going to be slower than either the
Tasin TS-108 (which is a #12 size) or the
While my grinder did process ~100 pounds of turkey thighs, I honestly think that this is expecting a lot from a grinder at this price point. If you must use your Tasin meat grinder for turkey thighs, I would recommend chopping or smashing the bones into smaller pieces to take some of the strain off the motor. For me, this would have been far too much trouble and I would have just stuck with chicken.
Please note that the Tasin and Weston grinder parts (as well as the Turbo Force brand mentioned below) are NOT meant to go into the dishwasher or they will be ruined. I don't have a problem with this since I prefer to wash them by hand anyway. The grinding plates are not stainless steel but I have never had any problems with rust forming. I simply wash them off with soap and hot water (using a nail to clean out any clogged holes) and then dry them and wrap them in a paper towel to wick away any moisture. I have never needed to add any oil to them.
However, some people spray the grinding plates with food grade silicone spray before storing them. This will help prevent rusting.
The STX Turbo Force 3000 grinder has gotten some good reviews on Amazon.com but I do not have an opinion regarding this grinder since I have not used it. I noticed that one reviewer stated that the grinder had trouble processing drumsticks. I would recommend using thighs and not drumsticks. Drumsticks have more tendons which tend to bind the grinding plate/blade/auger.
Northern Tool sells a grinder that looks like the Tasin TS-108; it is called the Northern Industrial #12 Electric Meat Grinder. I bought one in 2005 as a back-up grinder thinking that it was a Tasin. I was not happy with its power when it came to grinding bones and so I put it away. I recently tried to use it when my Tasin died but it lasted all of 5 minutes before it died. I would not recommend purchasing this grinder.
A discussion regarding the cost of good nutrition would not be complete without considering the cost of not feeding a species-appropriate, nutritious diet. The saying "pay me now or pay me later" really applies here. You can feed your cats well - either with a homemade diet or canned food - or you can pay the veterinarian later. I have often said that if people would feed their cats and dogs better, more vets would be out playing golf.
One must also consider the cost of time involved when dealing with a sick pet.
For instance, diabetes is a time-consuming and expensive nightmare to deal with. Inflammatory bowel disease is not much fun either, nor are skin allergies to inappropriate ingredients found in most commercial pet food. I would rather spend time making cat food than giving my cat insulin or cleaning up vomit or diarrhea from intestinal woes or dealing with any number of other diet-related problems that keep veterinarians' waiting rooms full of sick pets.
This is not to say that all feline diseases are necessarily linked to diet but many of them are. "We are what we eat" is not just a useless cliché.
.....I want to mention that there are few things more frustrating than slaving away in the kitchen carefully preparing a wonderful meal for your carnivore.....only to have them end up sniffing it and then walking away.
I don't like to see people get discouraged so I strongly suggest that you just take it slowly.
When I decided to start making cat food, I did not buy a grinder and all of the supplements right away. I just simply bought a chicken thigh and a chicken breast (some cats may like dark meat more than white or vice versa), thoroughly rinsed the meat with water, and cut it up into small pieces (the size of a pea or a bit larger) to see if my cats would eat raw meat. A couple of cats went for it right away and a couple of them just walked away.
Ok....that was a start.
(Most cats will like thigh meat better than breast meat because thigh meat has a higher fat content and fat increases palatability.)
I then mixed in a few of these small pieces with their canned food to get them used to the taste and texture of just plain meat. I also cooked some of the pieces to see how that went over. If your cat likes it cooked, you can then cook it less and less to get them used to eating raw or semi-cooked meat.
Other tips: Coat the meat pieces in parmesan cheese or FortiFlora. FortiFlora is a probiotic that I use to entice cats to eat. I do not use it as the label states since I am not using it for its probiotic properties. Instead, I am using it as I would if I wanted to season my own food with salt and pepper. As little as 1/10th or 1/20th of a package sprinkled on top of food can go a long way to entice a cat to eat something new. This is because FortiFlora is formulated using animal digest which is the same substance that pet food manufacturers coat dry food with to make it very palatable for cats and dogs.
FortiFlora has an expiration date on it which I don't pay any attention to since I am not using it for its probiotic properties. Therefore, I don't care if the 'good' bacteria in the product are dead or not. I am only using the product because most cats really like the taste of it. I think that all cat owners should have it in their cupboard in the event that you want your cat to try something new or they are ill and not wanting to eat anything. A box of it may very well last you a lifetime.
I experimented in various ways as stated above for a couple of weeks before I bought a grinder and the supplements. Much to my surprise, several of my cats actually immediately preferred what I made for them over the commercial canned food that they were eating. To this day, several of my cats will not even eat canned food anymore - they will only eat their homemade diet. I have created little obligate carnivore monsters who hold out for their species-appropriate diet.
Another option before purchasing the grinder and supplements is to try a commercially prepared raw food diet. Feline's Pride uses a recipe very close to the one on this page and several of my cats gave it a 'two dew-claws up' vote when it was offered. This diet is free of any grains, vegetables and fruits. However, when shipping is considered, it is very expensive.
Another choice for a commercial raw diet is Nature's Variety raw Medallions. This diet is comprised of 95% meat and bones and 5% fruits and vegetables which is a reasonable blend. It is also grain-free. It is cheaper and easier to find than Feline's Pride but I find that more cats will eat Feline's Pride when compared to Nature's Variety Medallions.
A third option is to purchase TCfeline premix powder from the Raw Meat Cat Food Company (formerly, Feline Future). Note that there are different pre-mixes depending on whether you want to add fresh liver along with the fresh meat (preferable) or, if you don't want to handle fresh liver, then you can use the TCfeline Plus which has liver powered added.
The TCfeline pre-mix powder is to be mixed with water, ground meat and skin (no bones), and liver unless using the Plus version. Please be aware, however, that I am not advising to use pre-ground meat, in the raw form, that has been sitting in a supermarket case so you will still have to find a way to grind up whole, boneless cuts of meat. Food processors work well for meat but not bones.
Please see the Safety Issues below for more information on pre-ground meat. If you want to use the TCfeline pre-mix powder, then I would suggest buying chicken or turkey thighs (with the bone and skin) and baking as discussed in the Safety section below. After removing the thighs from the oven, immerse them in cold water to stop the cooking process and to cool the meat so that you can debone it. After deboning the thighs, run the meat and skin through a food processor. I discuss how much skin to use in the Ingredient section below.
I would also like to mention that the recipe on this page is adapted from earlier work done by Natascha Wille of Feline Future. I am very grateful to Natascha for her pioneering work in this area.
I did notice one statement on the Feline Future (now Raw Meat Cat Food Company) webpage that I need to address. I would not let a cat go without food for 48 hours when trying to get them to switch to a new diet. There is no reason to be that extreme. Time and patience is the key - not starvation. I will let a healthy cat go without food for about 18 hours and then offer them some of their regular food if they will not eat the new food that you are trying to introduce. See Tips for Transitioning.
Please keep in mind that many cats are not going to dive into any new food right away! It takes time, patience and some tricks to transition cats onto a new diet. (It took me 3 months to get my cats off of dry food and eating canned food but it took less time to move them from canned to homemade.)
Also note that I have seen cats go from dry food to a raw or semi-cooked diet - and still refuse to eat canned food.
If your cat does not take to a new food immediately, don't get discouraged. Try mixing the new food with their existing diet of canned food at a ratio of 10% new to 90% old and then gradually increase the new diet from there.
Your cat may make it easy for you and show enthusiasm for the new food right away....but many (most?) will not. It took one of my cats (Toby) many months before he would start eating this diet with any consistency and when he finally did start eating it, I noticed that he was picking out the pieces that got a bit cooked when I was warming the food. Toby still is not terribly keen on strictly raw meat so he gets his semi-cooked. See below for a picture of how he likes his 'raw' diet half cooked and half raw. I often cook it even more than is shown in the picture below. Interestingly, Toby is one of my cats that does not like canned food.
Making cat food is not difficult. I am a walking disaster in the kitchen and it is my least favorite room in the house. If I can make cat food, anybody can. I won't lie - it can be a bit time-consuming - but it is definitely not difficult or complicated. If you can follow a simple recipe, you can make cat food. I usually prepare enough food for 8 - 10 weeks at a time but I have also used food that has been in my freezer for up to 1 year.
I was afraid that the 1 year old food would be freezer burned but I rinsed the top ice crystals off and my cats were fine with it. And...they are normally very picky cats.
The time that I spend making cat food is much less time than is involved in caring for cats that become ill from poor nutrition.
In a nutshell - before I go into more detail below - I grind up meat, bones, skin, and liver. I then make a supplement slurry by adding vitamin B-complex, vitamin E, fish oil, taurine, and iodized lite salt (if using poultry thighs) to water.
After I am sure that all of the supplements are thoroughly dissolved in the water, I mix the slurry into the ground up meat/skin/liver and then portion it into containers and put it in the freezer.
If I was not so lazy, I would use the eggs that are listed in the recipe below. Truth be told, I have not added eggs to the recipe for many years so I will leave that open as an option. If you can swing it - add them. They are very nutritious - especially the yolks.
I also cut some of the meat into chunks for dental health - when I am not being lazy.
Of course your cat has to have a healthy mouth to start off with when pushing the chewing issue. No cat will want to chew on any type of food if he has a painful mouth!
See the Dental Health section below.
The picture of the ground thighs shown below was taken when I was just rinsing the thighs off in water - versus baking as mentioned above. Therefore, the meat below appears to be a deeper color of red that it will if you partially bake the meat.

Please also see a very helpful pictorial section on Anne Jablonski's website at catnutrition.org.
In addition to the great pictures that Anne has on her website, she also has some 'frequently-asked-questions' that address many of the issues that come up when people are new to making cat food.
Also, if you are interested in learning more about feline nutrition, please read Michelle Bernard's book Raising Cats Naturally.
I tend to be a bit lazier than Anne so the information here will differ from her way of doing things just a bit. I will point out where I deviate from her methods and then you can decide for yourself how you would like to proceed.

With Bones....or Without Bones...and How Much Bone to Use?
One of the most important issues to address when feeding a homemade diet is the calcium-to-phosphorus ratio. Keep in mind: Bones = calcium.....Meat = phosphorus.
When a cat eats a bird or a mouse, he is getting a naturally balanced diet since he is eating both meat and bones.
Always remember that calcium is not an optional 'supplement' but a very critical component of the diet.
The bones must be ground with the meat (preferable), or another source of calcium must be added to the recipe if only meat is used. A cat cannot live on meat alone with no source of calcium.
Meat is high in phosphorus but does not contain much calcium. Therefore, a calcium source must be supplied and it must be done in the proper ratio considering the phosphorus in the meat. The most obvious - and best - way to add calcium to the recipe is to grind the bones with the meat.
I am a stickler for using fresh bone versus bone meal or calcium carbonate. You will not find a substitute source of calcium (bone meal, egg shells, etc.) that has all of the elements that are contained in fresh bone. Bone meal is heavily processed and the nutrients in the marrow will not survive the processing intact.
Plus, it is so easy to just grind the meat and bones together. And....deboning meat is not much fun and I do not advocate the feeding of pre-ground supermarket meat fed in the raw form. The bacterial load can put your cat at risk for severe illness.
September, 2011 update: For people who are unwilling or unable to purchase a grinder, I have finally 'given in' and added to the recipe section below the amount of bone meal needed to balance a boneless diet. However, you will still need a food processor to grind up the meat, skin, liver, and eggs since, again, I do not advocate using pre-ground supermarket meat. You will also have to debone whole cuts of meat such as chicken or turkey thighs. (In the long run, most people come to realize that it is much easier to just use a grinder.)
Back to bone.....how much to use.....
When the typical prey of wild cats is analyzed, we see that there is a fairly wide range in the calcium-to-phosphorus ratio in these prey animals so we do have some leeway when dealing with this issue.
Note that when small wild cats eat mice and small rabbits they usually eat the entire carcass - including the entire boney skeleton of their prey - whereas the larger cats (lions, etc.) strip the meat off of the bones leaving much of the skeletal structure of their prey behind. This fact illustrates that there is a wide variation in how much bone material wild cats consume.
Taking a logical look at the calcium-to-phosphorus ratio (bone-to-meat ratio), it would seem that the easiest way to ensure having a proper ratio is to use a whole carcass of whatever animal you are choosing as a food source. However, after witnessing constipation in many raw-fed cats and watching lions strip the meat from the bones - leaving most of the bones behind - I am not comfortable feeding as much bone as that found in whole chickens, turkeys, or rabbits.
Therefore, I use poultry thighs, which have a lot of meat relative to the bone. I dilute the bone even further by removing 20-25% of the thigh bones. If I am grinding 20 thighs, I remove 4-5 bones.
I also add boneless poultry meat (including the fat and skin) to the whole carcass ground rabbit for the following reasons:
If you choose to grind up an entire carcass and not 'dilute' the bone with added boneless meat, then I would suggest at least leaving out the back and neck since these are the parts of the chicken/turkey with the highest bone-to-meat ratio.
On a good note, if you do choose to grind up whole poultry carcasses, in considering the bone-to-meat ratio, our commercially raised chickens and turkeys will most likely have a lower bone-to-meat (higher meat-to-bone) ratio than a wild chicken/turkey given that poultry producers do whatever they can to promote 'meaty' birds for human consumption.
But all that said, unless you are trying to save money by using whole carcasses, I suggest just using poultry thighs which will lower the bone content of the food since the thigh is the 'meatiest' part of a bird's body that contains a bone. Also, cutting up carcasses is not only an unpleasant task but it is also very time-consuming.
It is not uncommon for cats to experience some constipation issues when started on a homemade diet. The reasons for this are variable but one cause may be the addition of too much bone to the diet. Another reason may be that the new diet is simply very foreign to an intestinal tract that has only dealt with dry food in the past and now needs time to adapt to a new diet, that is, if it can adapt.
Please keep in mind that cats on a homemade diet, such as the one discussed on this webpage, do not pass feces in the same volume, consistency, and frequency that a cat on a dry food diet does.
I have many people write to me stating that their cat is "constipated" simply because they are not passing stool every day. This is not necessarily a sign of constipation. Cats on a low residue diet will often not pass stool every day. There is very little waste contained in this diet and so the volume of feces will be less. Also, the feces of a cat eating the diet discussed below are often dry and crumbly.
This is a picture of feces from 2 separate bowel movements from my cats. In other words, an average bowel movement from my cats is half this volume - or even less. I crushed 2 of the fecal pieces to show how dry and crumbly it is. The feces from my cats also has very little odor!
Signs of constipation include straining without production of feces, crying in the litter box and acting distressed, as well as excessive licking of the anal area. Defecating outside of the litter box can also be a sign of constipation. These cats often either associate the litter box with pain and develop a litter box aversion or they simply get discouraged and impatient when trying to defecate in the litter box and end up going elsewhere.
When I first started feeding my cats a meat and bones diet over 9 years ago, 2 of my cats did experience a few episodes of minor constipation (cried one time in the litter box but were able to pass the stool within one minute) over the course of the first 2 years. I played around with the psyllium by increasing it, decreasing it, and then finally omitting it. All of my fooling around with the psyllium amount did not seem to make any difference in the moisture content of the stools.
The next step that I took in trying to deal with the constipation issue was to decrease the amount of bone that I was using. I started removing 20%-25% of the bones from the thighs. Did this help with the constipation issues in my two cats? I am not sure. The problems were minimal and infrequent so this made it difficult to accurately assess the situation. That said, I still remove 20-25% of the bones.
For example, if you are processing 20 thighs, remove 4 - 5 of the bones.
Wings, necks and backs are all parts of the chicken with a very high bone-to-meat ratio. These parts of the chicken should never be used as the sole component of the diet. I suspect that these body parts make up a large percentage of some of the commercial raw diets since they are cheap and are part of the 'discards' from the human-targeted market.
April, 2011 update: One of my cats, Robbie, has an anatomical abnormality in his rectum and needs to have his stools softened to facilitate defecation. I have been using guar gum which is a soluble fiber source and it is working very well.
I purchase the guar gum from Whole Foods Market or online here.
There are two types of fiber sources: soluble and insoluble.
Soluble fiber traps water in the stool, thereby softening it, but it does not swell as much as insoluble fiber. It is fermented into compounds that can be helpful for colon health.
Insoluble fiber (e.g., cellulose from vegetables) also traps water but it swells - adding bulk to the stool. However, this is not what we want for cats. Cats are not designed to eat a high plant fiber diet that results in a high volume (large diameter) stool.
Vegetables contain predominantly insoluble fiber making them much less desirable for treating constipation in the cat.
I have been adding ~1/8 of a tsp of guar gum to 3 ounces of a meal of the recipe on this site + plus an extra ~2 TBS of water. You can experiment with a bit more guar gum and water if you want to. (I am not adding the guar gum to the whole batch of food since I am playing around with the amount.)
There is one drawback to using guar gum....you will no longer be able to brag that your cat's feces do not have any odor. The feces of a cat fed the recipe discussed on this webpage (without guar gum) have very little odor but guar gum is fermented into some pretty stinky gases by the bacteria in the colon.
7/2/11 update: I have been using guar gum for 3 months as noted above and the smell of my cats' feces is not as bad as it was when I first started using it and the gas production has subsided significantly.
As discussed above, I use chicken, turkey, and rabbit.
The thighs need to be finely ground.
I also purchase chicken livers at WFM.
This product does not have to be re-ground.
Note that each rabbit comes with its own liver (and other organs) so no extra liver needs to be purchased.
For people on the east coast, a rabbit supplier is www.hare-today.com (814) 587-2178. I have no idea how finely this company grinds their food but it is not as fine as the product mentioned above.
Side note: Of course there are other issues involved with commercially-raised meat besides antibiotics and hormones such the diet they are fed, how humanely they are raised, etc., but that is outside the scope of this webpage.
In addition to chicken, turkey, and rabbit, good choices include Cornish game hen, guinea fowl, quail. Duck can also be fed but be aware that duck is typically very high in fat which may be a problem for some cats.
I stick to poultry and rabbit and do not feed beef or fish because poultry and rabbit are closer in composition to what a small cat would eat in the wild. Also, beef and fish have been shown to be hyperallergenic in some cats and if you used beef, you would have to use bone meal and I greatly prefer using fresh bone.
Raw fish should never be fed in large amounts because it contains thiaminase which will lead to a thiamine deficiency in the cat.
Regarding poultry: You can either buy whole carcasses and cut them up to fit into the grinder (leaving out the backbone/neck), or you can use dark meats (preferably thighs - more meat/less tendons), or a combination of dark meat and breast meat.
If using some breast meat, I would not use more than ~15% because it is very low in fat, is more expensive, and has no bone for calcium.
At the beginning of my cat food-making days, I bought whole rabbit carcasses (because they were cheaper than the ground carcasses) but soon tired of the work involved. Plus, I am dangerous with a knife....I ended up bleeding too frequently. So I now purchase pre-ground rabbit instead of whole rabbit.
As noted above, I only buy poultry thighs and never whole carcasses. The extra savings is just not worth the hassle of having to cut them up and I like to use less bone for my cats' diet as discussed under the bone section above.
Note that chicken legs = thighs + drumsticks. I buy thighs - not whole legs since thighs have a higher meat-to-bone ratio than drumsticks. Thighs also have less tendons than drumsticks which makes the meat easier to chunk and makes it easier on the grinder.
Drumsticks may be cheaper but, in the long run, thighs are a better deal because of the higher meat-to-bone ratio.
Chicken thighs (with bone and skin) are easy to send down the grinder tube.
Turkey thigh bones, on the other hand, are obviously bigger and tax the grinder more than chicken thigh bones.
In order to save my grinder motor, I send all thigh bones down with the hip joint (asymmetrical end/ball joint) first - never the knee joint (symmetrical end). This is because the auger of the grinder will 'grab' the 'ball' of the hip joint easier than it will grab the bigger, symmetrical knee joint.
(I will try to remember to take a picture of the two ends of the thigh bone the next time I make cat food.)
With turkey thighs, I stop the grinder before the knee joint advances to the auger. I then back up the grinder and remove the knee joint end of the thigh bone and discard it. My Tasin grinder is a workhorse but I don't want to push it too hard and ask it to grind large knee joints of turkey thigh bones.
Many opinions exist regarding the ingredients that should be included in an optimal homemade feline diet. Everyone is free to do their own research and come to their own conclusions.
The diet that I choose to feed is very basic. Some of the elaborate and complicated recipes found on the internet are enough to cause anyone to abandon the idea of making their own cat food and that is a shame. It does not have to be that complicated and involved.
The diet of a wild cat is pretty basic - they eat other small animals, often leaving the stomach, intestines, and some bone behind. They do not consume a large amount of grains, vegetables, or fruits - ingredients often present in large quantities in some recipes and in many commercial raw pet food diets.
I always use a recipe that includes finely ground bones.
I get fish oil, taurine, vitamin E, and vitamin B-complex from iherb.com or Whole Foods Market but there are numerous sources for these items.
If you order from iherb.com, remember to use the code LIS675 for $5 off your first order.
If your cat is thin and needs the extra calories, leave all of the skin on the meat. If your cat is chubby or has had pancreatitis, remove ~75% of the skin. (Some cats that have had pancreatitis do better on a low fat diet.) If he is just right, remove ~50% of the skin.
Do not remove the excess fat around the meat no matter the condition of your cat. Cats need a reasonable amount of animal fat in their diet. In fact, I have been playing around with adding a little bit of bacon fat to individual meals to give my cats a variety in flavor and to also increase the fat content (and therefore the caloric density) since one of my cats is older and a bit on the thin side.
I baked 18 ounces of the fattiest nitrite-free bacon I could find and it yielded 16 TBS of fat. I used a broiling pan to catch the drippings. Cook it slowly until the bacon is dry and crispy. That way, you will collect the most fat from the bacon. The dried bacon makes nice bacon bits for non-vegetarians. Or you can feed them to your cats as treats. Nitrites in cured meats is a controversial subject so I opted to purchase nitrite-free bacon from Whole Foods Market.
When I first started making cat food, I removed all of the skin - figuring that my cats are indoor-only and are not burning off as many calories as an outdoor cat would be. (I am not sure how true this is because ever since I started feeding them a better diet, they race around the house like crazy - even my 15 year old cats.)
My cats did lose weight (a good thing) on the skinless chicken diet but then I worried about the fact that in the wild they would be consuming the skin of their prey so now I use at least half of the skin on the chicken thighs. As mentioned above, I also add in some chicken/turkey meat with skin/fat to the rabbit meat and bones since the rabbits are skinned prior to processing and because rabbits are very low in fat.
If you are not using whole carcasses of chickens or rabbits but are using chicken parts instead, use all or mostly dark meat (thighs) since dark meat has a more appropriate amount of fat than white meat.
Breast meat does not contain enough fat if it were to make up the whole diet but it is fine to use some breast meat as long as it is not over ~15% of the total weight. That said, I never use breast meat because it is too expensive.
You will note that I do not include any vegetables or fruits in my cats' diet. There seems to be a strong anthropomorphic drive for the addition of vegetables to a carnivore's diet - some people just can't get past the idea that while vegetables may be good for humans, they are not a dietary necessity for a carnivore and will often cause problems in the digestive tract of the cat if fed in large amounts.
Cats lack the digestive enzymes necessary to process raw vegetables and fruits into an efficiently usable form. Many people insist on adding large amounts of species-inappropriate vegetables to a carnivore's diet arguing that they would eat them along with the stomach and intestines of their prey. However, these arguments do not take into account the fact that this vegetable matter is pre-digested by the prey's own enzymes - enzymes that are lacking in the cat.
In addition to this very important fact, the amount of vegetable matter in the average bird or mouse is extremely small and often the stomach and the intestines are not even consumed by the cat.
That said, some people do use a small amount of vegetables and I don't have a problem with that as long as the amount is minimal (~5%). If you choose to use a small amount of vegetable matter in this diet, do not feed them raw. Steam the vegetables first to help break them down to a more usable form for a carnivore.
Regarding grains - please disregard recipes that add grains to an obligate carnivore's diet. We want to refrain from feeding cats as if they were horses or cows.
Please check back to this webpage periodically for any updates to the recipe.
Also see below the recipe for links to products that I purchase from iherb.com.
Please note that I do not recommend this recipe for cats with CKD (chronic kidney disease) - formerly known as CRF.
Also note that I do not favor the many recipes on the internet that use large amounts of potatoes, pumpkin, squash, rice, etc., for CKD patients. In almost all cases of CKD, feeding these species-inappropriate ingredients is not only unnecessary but can be detrimental to the health of the patient. See below.
September, 2011 update: Since writing this page many years ago, I have pushed heavily for the use of fresh bone (versus bone meal) as a calcium source. This requires buying a grinder.
However, many people are either unwilling or unable to purchase a grinder so I am finally 'giving in' and will state that if you are going to use 3 pounds of boneless meat and skin, then the amount of bone meal (NOW brand linked below) to use is 2 1/3 tablespoons. That is 2 tablespoons + 1 teaspoon....or....7 level teaspoons. (1 tablespoon = 3 teaspoons)
A commonly asked question: "What do I do with the bones left behind in the grinder?"
Answer: Discard them.
I use the following ingredients - in amounts listed - per
3 pounds of poultry thigh meat/bones/skin
2.25 lbs of whole carcass ground rabbit + 0.75 lbs of boneless chicken or turkey meat/skin/fat (see reasons above):
For people living outside of the United States who cannot source Morton Lite Salt with iodine, use 1/2 tsp of regular salt (sodium chloride) with iodine.
When I first started feeding raw, I used psyllium whole husks but I did not see much difference in their stool consistency. It was still very dry and and low in volume but then I came to realize that this was normal for a cat eating a diet like this. I was just so used to the big, bulky, stinky stools of cats fed commercial canned and dry diets.
For the next 8 years, I added no source of fiber.
Left = homemade diet.............Right = canned food diet
Take my word for it....the one on the left = very little odor
The one on the right = very stinky
Recently, Robbie, my best buddy with no colon whose picture adorns the top of all web pages on this site, has needed his stools softened due to an anatomic abnormality in his intestines. I have chosen to use guar gum powder but I am not adding it to the entire batch. I am just adding it to individual meals so that I can play around with the amount.
I am using ~1/8 per 3 ounces of food. If you are going to try it, start with 1/8 tsp and work up from there. Also, add more water to the food since fiber 'soaks up' water.
There are two types of fiber - soluble and insoluble. Psyllium is a combination of both types. Guar gum is strictly soluble. I use this source of fiber because it does not seem to add as much bulk to the stool when compared to insoluble fiber but it does increase the water content of the feces, thereby softening it.
Soluble fiber also has some properties that promote intestinal (colon) health.
If you want to use psyllium, add 2 tsp if using psyllium husk powder. If using whole psyllium husks, use 4 tsp.
If using any fiber source, be sure to add more water to the this recipe.
At the request of several readers, here are links to specific products that I purchase from iherb.com:
Fish oil - This is a link to Nature Made 300 capsules for people who make a lot of food.
Fish oil - This is a link to Nature Made 100 capsules for those with fewer cats.
Both of these fish oil products have 300 mg of EPA + DHA per capsule. There are other fish oils with a higher level (called "super", etc.) but they are more expensive per gram of EPA + DHA.
Note that I strongly prefer using fish oil capsules - not bottled oil. Capsules stay fresh longer than bottled oil which can become rancid. Make sure that whatever you buy is not lemon flavored!
Do not use cod liver oil.
Vitamin E - I prefer using the d-tocopherol (natural) versus dl-tocopherol (synthetic) vitamin E.
Vitamin E - another option
You can also use liquid vitamin E in gel capsules but you will need to either dissolve them in the water or poke them with a pin and squirt the oil into the water. I find dry vitamin E capsules easier to work with.
B-Complex - 50 mg per capsule
B-Complex - 100 mg per capsule for larger batches
Note that these B-Complex products do not contain vitamin C.
Lite salt with iodine - sample link to show picture - can be purchased at most local grocery stores (not available at iherb.com)
Salmon vs fish oil: I prefer to use fish oil from smaller fish such as anchovies and sardines. Oil from fish that are lower on the food chain are less contaminated with heavy metals and other impurities.
If you prefer to use salmon oil, here is a link to a product that I used for many years before switching to oil from smaller fish:
Bone meal powder - for use if you are not going to buy a grinder. Please note that different brands of bone meal powder vary in their composition. I have calculated the amount needed based on the NOW brand product so please use this brand if possible.
Most cats eat 4-6 ounces/day. Therefore, this recipe yields enough food for one cat for approximately 10-14 days.
If using capsules with dry ingredients, open them and add the powder to the water. If using tablets, dissolve them in the water.
You can either poke the fish oil capsules with a pin or cut the tip off with scissors and squirt the oil into the water....or you can do what I do and just dissolve the fish oil capsules in the water for ~10 minutes and then, once they are somewhat dissolved, make sure that all of the oil is liberated from the capsule by squeezing the capsules with your fingers within the water. Using warm water helps dissolve them faster. I use this method because I make so much cat food at one time that it would take forever to poke each capsule with a pin.
It is fine to leave the capsules in the water. They are gelatin (a protein) and most cats readily eat them.
For the boneless poultry meat and skin that you are adding to the pre-ground rabbit carcass, you can either use a grinder or a food processor for the meat that you don't chunk for dental health.
Notes on why I omit/alter certain ingredients that you may see in other recipes:
The thyroid gland of a cat's natural prey is a good source of iodine but when using chicken or turkey thighs - and, therefore, no thyroid gland - we need to add Morton's iodized Lite salt as a source of iodine. I use Lite salt instead of regular table salt because Lite salt is a mixture of sodium and potassium versus table salt which is all sodium.
The iodized Lite salt (or, for non-US residents, regular iodized salt) is not an option. It is a definite requirement when using only chicken or turkey parts - or any whole carcass that does not include a thyroid gland.
Also keep in mind that when we use poultry, we are missing the blood and its sodium and potassium. The Lite salt adds in some sodium and potassium
If using ground rabbit, I would assume that the thyroid gland is included. However, you may want to call your supplier and ask if this is the case. If it is, I would not add the iodized Lite salt.
Be sure to use all of the blood that comes with any ground food since blood contains valuable nutrients - including sodium and potassium. Note that the ground rabbit from wholefoods4pets.com comes with a lot of blood included which is why I do not use Lite salt when making rabbit food.
But, that said, in light of the recent contamination of eggs with salmonella, I would lightly cook the egg whites anyway. If you want to be extra safe, then lightly cook the entire egg (white and yolk). I find that soft boiling them (~6-8 minutes) works very well but some people like to scramble them in a bit of butter. Be be sure to run them through the grinder or food processor in order to break them up so that you can mix them into the food uniformly.
Egg whites (not yolks) are an excellent source of phosphorus-free protein. This is a great additive as long as the cat has not shown any allergy/intolerance for egg protein. (Although, technically speaking, if a cat is allergic to eggs, I would assume that he would also be allergic to chicken meat but maybe not??)
For cats with gastrointestinal issues or any signs of allergies, I would suggest omitting the eggs when first introducing this diet. They can always be added in later as a single change to the diet. That way, any negative reaction can be monitored. If your cat does not like the diet, try omitting the eggs. Some cats just do not like eggs. I consider the eggs to be an optional ingredient.
Note: I do not recommend this recipe for CKD (Chronic Kidney Disease) cats.
(CKD is also known as CRF - Chronic Renal Failure - but we are trying to move away from the word "failure" because it is such a negative term.)
There are other recipes that are more suited to feeding cats with this condition. However, the nutritional needs of these cats must be discussed on an individual patient basis. The reader can reach me via email to request a phone consultation if they wish to discuss an appropriate diet for a CKD patient.
All consultations are conducted via the phone (or Skype) only after the patient's medical records, including lab work, have been provided for my review. General CKD medical management to prolong the length and quality of life, in addition to appropriate dietary issues, is discussed during the consultation. My CKD consultations take up approximately 2 hours of phone time since there is a lot to discuss if optimal CKD medical and nutritional management is desired.
Again, as noted above, I do not see diets that are loaded up with potatoes, pumpkin, squash, rice, etc., as being healthy diets for any cat - including CKD patients.
Here is a video that my friend, Anne Jablonski of catnutrition.org fame, put together. Please note that Anne uses a plate that creates a very coarse grind whereas I prefer a more finely ground product. Anne has never had any problems with her cats eating larger bone pieces but I have. You will see that her grinding process goes much faster with the plate that she uses.
See Anne's Pictorial here.
I prepare food for my cats in two basic ways - depending on if I am using pre-ground rabbit or whole chicken/turkey thighs from Whole Foods Market:
1) Ground rabbit (meat, bones, and liver): The ground rabbit is shipped to me in a frozen state in 4 lb packages. I thaw it and mix in the ground and chunked chicken/turkey thigh meat and skin as discussed above.
The supplements are added to the water and, once they are all dissolved, this supplement slurry is added to the meat/bones/skin/liver/eggs. Since I make so much food at one time (30 - 50 lbs), I find it easiest to use my hands to thoroughly mix the food. After the food is mixed well, it is portioned into containers and put into the freezer.
Note that for this preparation, a grinder (for use with bones) is not needed but a food processor is.
2) Chicken/turkey thighs: The second way that I make food is to:
When I say "chunks" I mean pieces of meat about the size of a die (~1/2 inch cubes) or a bit smaller at first and then larger (size of your thumb) once your cat gets the hang of chewing on them. The bigger, the better. Keep in mind that raw meat is more tenacious (and better for teeth) than cooked meat.
I would prefer it if the chunks were raw like the ones in the middle of this picture. Raw meat is harder to chew than cooked meat and will, hopefully, exert more cleaning action on the teeth. That said, nothing is as beneficial for dental health as daily brushing.
Since I really hate chunking meat by hand, I tried the plates below which were a waste of money. Even the one with three large holes ground the meat too finely to allow for any dental health benefits.
Mixing up the supplement slurry:
Note that it is helpful to put the fish oil capsules in warm water in advance of mixing up the supplement slurry. It takes about 15 minutes for them to dissolve and I use my hand to make sure that all of the oil is squeezed out of each capsule. Some people poke the fish oil capsules with a pin but I use ~50 capsules for my large batches and that would take far too long.
It is ok to leave the capsules in the water. Most cats readily eat them but if your cat is not fond of fish, then you may want to remove them.
Remember to add the Lite salt if using only chicken/turkey thighs. This is an important source of iodine since the thyroid gland is not included when using only chicken/turkey parts.
Ideally, the food should only be in the refrigerator (in a completely thawed state) for 48 - 72 hours so keep that in mind when choosing your container size. The average cat eats about 4-6 ounces per day. When I was first starting to feed raw, I used baby food jars so there would be no waste during the transition. I then quickly graduated to larger plastic containers that hold 1-1.5 pounds. People with just one or two cats need to pick the container size that works for them.
You will note on Anne's site that she prefers not to warm the food in the microwave. Instead, she heats it in hot tap water. This method would never work for me since it takes forever to get hot water at my sink and I hate wasting water. Plus both my cats and I are impatient so all of my cat food-warming is done in the microwave. Depending on the level of thawing, I may heat it for 10 -15 seconds then stir. I repeat this several times so that the food is not cooked but is just warmed to 'mouse body temperature'.
Exception to the above: I found that one of my cats, Toby, was (is) very stubborn about eating meat if it is completely raw but I noticed that he would eat the 'accidentally-cooked' pieces if I left it in the microwave too long. I have tried to cook it less and less over time but he is really stubborn about eating the completely raw rabbit so I humor him and feed it to him half cooked and half raw - or sometimes it is cooked even more than is shown in this picture.
Toby eating his half raw and half cooked rabbit.
I do not worry about cooking the ground bones. I grind them so finely that this is not even a remote concern for me.
There is a very helpful page on the Raw Meat Cat Food Company website. It provides information on canning cat food. My Robbie does not do well on any commercial canned food (he gets severe diarrhea) so this is a great alternative for me in an emergency situation so I don't have to use commercial canned foods.
I purchased this pressure canner and now have homemade canned chicken, turkey, and rabbit cat food available for periodic feedings and for emergencies. This canned food also comes in handy if I have to be gone for 12 hours on a hot day. I leave this food out instead of the raw/semi-cooked diet. This canned food is also safe for human consumption so it doubles as an emergency supply for both two-legged and four-legged members of the house.
Please note that I said for "periodic feedings". I have no idea what nutrients and in what amounts are destroyed in the canning process so I would not want to feed this diet as a sole diet for more than a couple of weeks during an emergency situation.
Of course your cat has to have a healthy mouth to start off with when pushing the chewing-on-chunks-of-meat or tooth brushing issue. No cat will want to chew on any type of food or have his teeth brushed if he has a painful mouth!
If in doubt, please be sure to have your veterinarian examine your cat's mouth. Poor dental health is the most commonly overlooked health problem in our cats and dogs!
Unfortunately, people (including myself....) do not take their cats in for dental cleanings/exams as often as they should. We need to stop over-vaccinating cats and pay more attention to their dental needs. Please see my Vaccine page for more information on the rampant over-vaccination that occurs among our cats and dogs.
I would encourage you to have your cat's teeth properly cleaned and examined (under general anesthesia - *not* anesthesia-free) if you have not already done so. You want to know that your cat's oral cavity is in a healthy state before you push the issue of chewing on chunks of meat and/or tooth brushing. If you start your cat off with clean teeth, you can then go forward and be proactive in keeping them clean.
It is important to note that chewing on meat and tooth brushing will not remove the plaque that is already on the teeth.
Only professional scaling under general anesthesia can do this in an effective and safe manner.
Unfortunately, like most cat and dog owners, I have been ignoring my cats' dental health when using finely ground meat and bones and they are paying for it with unhealthy mouths.
Hopefully you will do better for your cat.
The reasons why my cats' dental health is not being addressed are:
1) I am being lazy. De-boning and cutting up meat by hand is time-consuming.
2) My cats are also lazy (Robbie has a perpetual 'Mommy, please cut my meat for me' look on his face....) and will often just eat around the chunks. Not only is this frustrating because the meat is wasted, it can also lead to an unbalanced diet.
If a large percentage of the meat in the diet is chunked....and the cat eats around the chunks....they will be eating too much ground bone/liver and supplements.
Therefore, watch your cat to make sure that he is consuming both the chunks and the ground-up portion. Otherwise, he will be eating an unbalanced diet.
And....if you have a kitten, train him to eat chunks of meat early in life!
One trick that you might try is to serve a full meal of 100% chunks - when your cat is ~12 - 18 hours hungry in order to get him used to chewing on meat chunks. Hunger goes a long way when trying to get a cat to embrace any new food - as long as your cat has a healthy, non-painful mouth.
As mentioned above, you can also try coating the chunks of meat in parmesan cheese or FortiFlora. My cats LOVE FortiFlora and would probably eat cardboard if I sprinkled it with FF. That said, some cats (~10-15%) do not like FF.
See Anne's pictorial here where she shows the size of the meat chunks that her cats are chewing on. You may have to start smaller - like the size of a pea - just to get them used to the texture of meat. Unfortunately, most cats are not used to doing what nature intended for them and they may take some time to get used to gnawing on chunks of meat.
Another good dietary option to promote dental health for your cat is to feed them gizzards. Gizzards are very fibrous and tough to chew and If your cat will eat them alone, they can be used as a great dental snack.
If your cats like gizzards, you can incorporate them into the batch of food since they are easier to cut up when compared to muscle meat. Just count the gizzards' weight as part of the 3 lbs of meat/bone/skin in the recipe above.
In order to promote dental health, many proponents of a raw diet use meaty bones. However, this is not within my comfort zone due to the risk of broken teeth, or swallowing sharp bone fragments. Plus, I don't want raw bones drug around my house.
When first starting to feed a homemade diet, you may not want to do much chunking if your cat will not readily eat the chunks. First things first....ie....get them to embrace the finely ground up meat and bones diet first....then see if you can get them to chew on chunks of meat.
Brushing your cat's teeth is the best way to keep his teeth clean if he will not chew on chunks of meat but, honestly, even if they do chew on meat? I would still suggest brushing their teeth as an added insurance policy. Please see this video that explains how to do this.
After 18 months of use, this tooth brush is very worn out and needs to be replaced.
This toothbrush is the only product that is suitable for cats and is the one shown in the video.
Please pay close attention to the statement in the video regarding a thorough dental exam by your veterinarian before starting a brushing program.
Many cats have very painful mouths but show no outward signs of this pain. If you try to brush your cat's teeth in the face of a painful mouth, all you will end up with is a cat that is scared - along with developing a strong aversion to toothbrushes. If this aversion occurs, you may never get him to accept tooth brushing once you have addressed the painful mouth with your vet.
In January, 2010, I started brushing Robbie's teeth after a dental cleaning under anesthesia and am kicking myself for not doing it sooner. Robbie builds up tartar faster than any cat I have ever dealt with and he really could use dental cleanings 2 times per year. Plus, his breath smelled awful! It actually smelled worse than his feces.
July, 2011 update: Robbie's teeth would have been a mess by now since his last dental was in December, 2009. However, since I have been brushing his teeth daily (or at least 6 times/week) for the past 18 months, his breath is still great and his teeth are very clean! I should have started doing this years ago!
Here is a video that I took in December, 2010. It is not a very good video but it shows that he tolerates it very well....and the kisses on the head are mandatory. :>)
February, 2012 update: It has been more than 2 years since Robbie's last dental and his teeth are still very clean and his breath has no odor. I am still brushing his teeth every night.
Understand that you will not be able to get to the inside of any teeth. I just focus the brushing on the outside surface of the upper and lower molars which is where the bulk of a cat's teeth problems lie. At first, Robbie was not as cooperative with the lower molars as he was with the uppers but now he willingly lets me brush both areas. He is also very good about having his canine teeth ('fangs') brushed. In fact, I start with his canines because he is so good about it.
Note that you will not be brushing back and forth like you would on your own teeth. That will annoy most cats. With Robbie, I swipe the tooth brush in one direction over and over again. Front to back, front to back, front to back....trying for ~8-10 swipes. Then the other side is back to front, back to front, back to front....
When first starting to train your cat, only swipe a couple of times then feed him a treat and let him go. Concentrate on the canine teeth and upper molars. Leave the lower molars until your cat has accepted the other areas.
It may take a month or more to get your cat used to this process.
Go slowly and be very patient!
Note that you do not have to use any toothpaste. A moistened (with water) toothbrush is all you need. In fact, I only use the CET toothpaste that I bought for Robbie as a treat after I brush his teeth. He likes the taste of it so I put a bit on my finger for him to lick off when we are done.
You can try using toothpaste but if you use too much, sometimes your cat wants to start licking and chewing and that will make it hard to brush his teeth. You actually want the cat to keep their mouth closed and still.
One final comment....when I brush the upper molars, I pull up/back the lip/corner of the mouth so that I can actually see them. However, with the lower molars, I keep my finger under his chin so that he keeps his mouth closed. I then slip the bristles between his lips and just 'feel' the lower molars and listen for the sound of the bristles against the teeth but I don't actually see them.
I find that it is easier to get the uppers brushed than the lowers.
Hopefully....one day soon....I will write a Dental Health webpage which will address this issue in more detail.
I buy only whole meats from the market for the following reasons:
When packaging for the freezer, use a container size that will be used up with within 2 - 3 days of being in a completely thawed state in the refrigerator.
You may be wondering what the difference is between the ground meat at the supermarket and the ground rabbit that I buy from wholefoods4pets.com. Wholefoods4pets process the rabbits and then they immediately freeze the final product versus refrigerating it. It arrives on my doorstep frozen.
This meat comes to me in such a clean state so that it would probably be fine if left in the refrigerator for 4 days but I still package it in containers to be used up within 3 days of being completely thawed in the refrigerator.
3) I want to use fresh bone versus bone meal and it is very easy to grind the meat with the bones. With regard to adding a basic calcium source (like calcium carbonate) - instead of using bone - you run the risk of feeding an unbalanced diet because these calcium supplements are just that - calcium only. Bone is a source of more than just calcium.
However, having said this, one of the reasons why I started partially baking the poultry thighs is because I did not want to have to worry about shipment dates. I wanted the convenience of buying meat on my schedule - not my butcher's.
However, I am not comfortable with the size of bone pieces that result from the use of this plate. In fact, my cats have gotten bones the size shown below stuck in their mouths causing them great distress. I have a 4 minute video of my Robbie violently pawing at his mouth because of a bone fragment that had gotten stuck. He was not happy and neither was I!
I often get asked about acceptable bone size. This is where I differ from many raw feeders. I tend to err on the side of caution and grind the bones very finely.
This picture illustrates a bone size that I am not comfortable with.
These bone pieces were taken from a single ground rabbit product obtained from wholefoods4pets.com. At my request, Mary (at WF4P) now offers an Extra Fine Double Ground product using what she jokingly refers to as "Dr. Pierson's microplate" to appeal to my paranoia about bone size. (The regular double ground still yields the bone size as shown in the picture above.)
If you want to save money, order the single ground (this will yield the bone sizes shown above) and then it will be your choice to feed as is or send it through your grinder using a fine plate.
With regard to the safety of raw meat diets, you will no doubt hear varying opinions on this issue. Many of my colleagues are adamantly opposed to the feeding of raw meat yet they think nothing of supporting the common practice of leaving bowls of dry food sitting out for pets to free-feed from which can be contaminated with fungal mycotoxins, bacteria, chemicals, or storage mites. It is very frustrating to witness this narrow-mindedness and lack of acknowledgement as it pertains to the contamination issues regarding dry food and treats - many of which have been recalled as noted below.
I would like to see my colleagues stop reflexively telling their clients that all raw meat diets are dangerous and understand that there are ways to source and prepare this diet that will actually make it safer than the commercial foods that they continue to recommend without any thought as to feline illnesses that these foods contribute to due to their species-inappropriate composition/ingredients, as well as the contamination issues.
I don't think that a single cat or dog caregiver in the US is not aware of the thousands of cats and dogs that suffered tremendously and died - or have been left with failing kidneys and a shortened lifespan/diminished quality of life - due to the contamination of commercial foods processed by Menu Foods in the summer of 2007.
While the Menu Foods recall was the largest pet food recall in the history of commercial pet food, make no mistake in thinking that this was the first time that cats and dogs have died after consuming commercial pet foods that have been contaminated with chemicals, bacteria, and bacterial or mold toxins.
However, keep in mind that the vast majority of these contamination disasters (outside of the Menu Foods tragedy) have involved dry food or treats - not canned food. Therefore, if you decide that you don't want to make your cat's food, please feed canned food and keep the dry food out of your cat's food bowl.
Dry food is simply not a very healthy or completely safe diet to be feeding to any cat.
See Urinary Tract Health and take a look at Opie's pictures. If humans would stop feeding dry food to cats, cats like Opie would not have to suffer from excruciatingly painful - and life-threatening - urethral blockages.
There have been many instances of mold toxin-related deaths of pets after eating contaminated commercial dry food. I have listed a few below but these tragedies are too numerous to list all of them.
The regulatory body for the commercial pet food industry does allow a certain level of mold toxins (found in grains) to be present in your pets' food. For me, this is unacceptable - especially when feeding cats - since grains have no business in their diet to begin with.
With regard to the extremely dangerous and life-threatening fungal toxins found in commercial dry food, this issue will never be a worry when feeding a grain-free diet - either in the form of canned food or the diet discussed on this page.
And if mold toxins and bacteria in dry food are not enough to cause us worry, please consider the fact that the fats contained in dry food become rancid over time - even with the preservatives that are added to the food. Heat, oxygen and light are all factors involved in fats becoming rancid. Keeping dry food in the refrigerator will help with the issue of heat but that still leaves the oxidation issue unaddressed.
Dry foods sit in warm warehouses and pet food stores before they even reach our pets' bowls - promoting rancidity of fats, bacterial growth, mold growth, and toxin formation, and proliferation of storage mites.
At the very least, dry food should be kept in the refrigerator but it is better to just refrain from feeding this type of food.
See this link for an abstract that discusses the issue of storage mites that were found in 9 out of 10 bags of tested dry food.
This link will take you to an article on a website maintained by the pet food industry. This article discusses the use of ethanol by-products in pet foods.
There is absolutely no doubt in my mind that many cats and dogs have died as a result of consuming commercial pet foods yet the cause goes unrecognized.
These deaths include the various illnesses that manifest themselves due to the species-inappropriate composition (composition = percentage of calories coming from proteins/fats/carbohydrates and the water content) of the diet, as well as out-and-out contamination issues as discussed above and below in the Pet Food Recalls section.
Unfortunately, humans just don't recognize these illogical and unsafe diets as the cause of the pet's illness. Humans - including veterinarians - often fail to put 2 + 2 together in many instances of ill health or death. Food is often the last thing to even be considered as a cause or contributing factor in the event of an illness or death.
As stated above, we all must work within our comfort zone. If you find that you are not comfortable feeding a raw meat - or semi-cooked - diet even when implementing the tips in my safety section, then please feed canned food and remove all dry kibble from your cat's diet.
Throughout the history of the commercial pet food industry, there have been numerous recalls of dry kibble pet food and treats due to contamination issues involving bacteria (salmonella, etc.) fungal mycotoxins, deadly chemicals, and storage mites. And to be fair, there have also been recalls of commercial raw meat diets.
The list below by no means includes all reported contamination issues. If it did, this webpage would be a mile long.
I have included links below that will take you to the websites of the manufacturers or to articles discussing the recalls/warnings. However, they seem to take these pages down not long after the recall is announced.
For a list of current recalls, please see truthaboutpetfood.com. This website lists pet food recalls and is much more current than the information below. I cannot keep up with the task of posting all recalls/warnings/dry pet food-related animal deaths and human illnesses/deaths on this page.
January, 2011: 200 cows recently died after consuming feed contaminated with moldy sweet potatoes. The mycotoxins produced by the mold was the cause of death.
February/March 2010: Nature's Variety raw chicken products - possible salmonella contamination. This company has recently implemented a pasteurization process to help ensure the safety of its future products.
January, 2010: Merrick Beef Filet Squares for dogs - FDA warning issued due to salmonella contamination of these treats.
October, 2009: Wysong recalls dry food with mold contamination.
October, 2009: Diamond Pet Food company recalls Premium Edge dry food due to thiamine deficiency which causes severe neurological damage and death in cats.
June 12, 2009: The U.S. Food and Drug Administration announced today it was suspending the temporary Emergency Permit issued to Evanger's Dog & Cat Food Co., Inc. The deviations in their processes and documentation could result in under-processed pet foods, which can allow the survival and growth of Clostridium botulinum (C. botulinum), a bacterium that causes botulism in some animals as well as in humans.
January 9, 2009: Chicken jerky treats for dogs. Here is an excerpt from VIN (Veterinary Information Network):
The U.S. Food and Drug Administration has received 153 complaints during the past 16 months about illness in dogs that have eaten chicken jerky treats and continues to take reports “at a steady clip,” an agency spokeswoman said Friday.
November 25, 2008: Mars Petcare US extended its October 28, 2008 voluntary pet food recall of dry food that affected 15 states, adding more product carriers and brands affected by possible salmonella contamination.
October 28, 2008: Mars Petcare US is yet again recalling another salmonella-contaminated dry food manufactured at one of their facilities. This time it is Special Kitty Gourmet which is sold at Wal-Mart locations in 15 states.
October 20, 2008: Hartz Mountain Corporation is recalling rawhide chips due to salmonella contamination.
September, 12 2008: Mars Petcare US, once again, is recalling salmonella-contaminated dry pet food. This company makes many different brands of pet food. There were many human cases of salmonella infection possibly linked to this food.
August, 2008: The California Public Health department reported salmonella contamination of Pedigree dry dog food. Pedigree is made by Mars Petcare US.
August, 2007: The FDA recalled several dry foods under the Natural Balance Eatables product line due to botulism toxin contamination.
January 2006 - September 2007: See this link for a CDC report on a multi-state (19 states) outbreak of salmonella in humans during 2006 and 2007. The source was dry pet food made at Mars Petcare US.
December, 2005: Some of you may also remember the deaths of many cats and dogs after they ate Diamond pet food in 2005. These animals became very ill - and many died - secondary to liver failure from mold toxins (aflatoxin) that were contained in the grains of a commercial dry kibble. Many cats and dogs died as a result of this contaminated food. The surviving animals will have permanent liver damage.

If you would like to read a more in-depth discussion of this topic, please see Dr. Zoran's wonderful paper entitled The Carnivore Connection to Nutrition in Cats.
As stated above, if you decide that you are not comfortable preparing your own cat food, please feed canned food and get the dry food out of your cat's food bowl.
