Potato must be well cooked. I boiled it just like I would for mashed potatoes.
Meat. I used ground red deer meat. I roasted the venison at 350 degrees for one hour just like I was making meatloaf. I chopped up the meat and spread it in the pan. Add the corn oil, the dicalcium phosphate, salt and taurine. DO NOT add the Vitaline vitamin. This does not get added to the food until you are about to serve it.
Roast the meat and other ingredients. Remove from oven. Turn off potatoes and drain them. Let both cool down.
Take out your food processor. You can grind this to the texture your kitty likes. It also can be just chopped and mixed. I put mine in the processor (potatoes and meat mixture) and mixed both until it formed the pāté look (just like canned cat food) but I was making a big batch. (See section where I list the amounts I put in for 8 pounds of venison.)
I then put the food in plastic storage bags. It will keep in the refrigerator for up to a week. Freeze the rest. I take out each portion from the bag in the refrigerator with a spoon, put it in their bowls and microwave it on medium-high for 30 seconds to get it to room temperature to serve it. Pulverize a Vitaline tablet and add one-fourth of the ground tablet into the cat food. Stir it in. (Do not serve the cat food hot. Kitties do not want their tongues burned.)
Four ounces of food per day. (Four ounces is about the size of a deck of cards, just like they tell humans.) My cats are very active so they eat a bit more and do not gain weight. If you feed your cats twice a day like I do, divide the portion in half and feed them twice. That way the food won't get dried out.
The diet tells you to switch your cats over to this diet gradually over 5 to 7 days so they don't get a tummy ache. You may not see results for 8 weeks; some pets require 14 weeks to see results. On the other hand, I saw results in less than one week.
DO NOT give them any other treats or other food if you want to see results-relief from an allergy. If you give them any other food or treat (including catnip), you have to start the process all over again.
Three more paragraphs of advice from Dr. Cecilia Friberg, DVM. Cats can't go without eating; they can develop liver problems! You should always consult with your veterinarian regarding any diet changes and if they believe this diet is appropriate. In some cases, diet changes can be a problem. Especially if your cat has any kidney problems, etc., you need to get the okay from your vet. Your vet should look at the recipe you intend to use and tell you if it's okay to try. It is also important that a diet (especially long term) be balanced.
Dr. Friberg recommends several good web sites. Go to The American Veterinary Medical Association's website, www.avma.org. On the left side about halfway down is a link to "Veterinary Specialty Organisations." Once there, find the American College of Veterinary Nutrition web site link (www.acvn.org). Go to "Links." They have a link under Pet Diet Evaluation to www.petdiets.com This will get you in contact with a board certified veterinary nutritionist who can formulate a diet based on your pet's dietary needs, protein source used, carbohydrate source, etc. There is a cost associated with this, but it is important that people have good information about diets and nutritional needs for their pets. This can be very complicated and require advanced knowledge from these experts!
There is also a link from the "Veterinary Specialty Organisations" page to all of the recognized specialty colleges in veterinary medicine. This is also a good resource for people who are looking for advanced treatment for their pets. Often people don't even know that there are veterinary specialists who can help them. The veterinary colleges tend to be less expensive than the private practice specialists, but are often located in small towns, etc. that require some driving, and not all colleges have specialists in all of the fields. Several do not have veterinary dermatologists, but if someone is looking for one, the www.acvd.org web site has a "find a dermatologist" map with all of us in the world!
