I wanted one too and found this online that sounded good but I have not yet tried it. >
A cat's daily diet should consist of four parts protein to one- two parts carbohydrates
It can be fed raw or lightly cooked depending on your cat and situation. Be sure never to feed any animal cooked bones. Always chop finely or blend raw vegetables to break down cell walls and make them digestible for your feline friend.
One part of protein is equal to
2 oz. meat or fish
1 medium egg
1/2 cup yogurt- note that 1/2 cup of yogurt counts as 1 unit of carbohydrate as well
1/3 cup cottage cheese- note that 1/3 cup of cottage cheese counts as 1 unit of carbohydrate as well
2 oz. organ meat-you can feed up to one unit of organ meat several times a week if desired.
You need to feed 1 to 2 units of carbohydrates per day
One part of carbohydrate is equal to
1 cup vegetables such as-broccoli, Brussel sprouts, green beans, peas, cabbage, spinach, squashes
1/2 cup fruits such as-melons, berries, bananas, tomatoes, apples; also carrots at 1/2 cup.
1/4 cup cooked beans, lentils or chick peas
1/3 cup of grains such as-oatmeal or barley can be added if you wish. These are the best of the grain type carbohydrates for a cat but note that grains in general are the least favorable type of carbohydrate. Try to limit or avoid these carbohydrates if your cat allows . Whole wheat pasta or brown rice are other options although not preferred.
1/2 teaspoon bone meal
Multivitamin for cats- whole food source is preferred. Your cat should be supplemented with 50-100 mg of taurine per day depending on the size of cat. Meat loses much of its taurine content when cooked. Check your multi to see if it is supplied or if you need an additional supplement.
500-1000 mg fish oil
Antioxidants as directed for felines
Note that this diet will not be adequate or appropriate for all cats. Be sure to check with your veterinarian before beginning this or any other new diet for your cat.
Hope you will let us know if you try it how it works out and if your cat liked it.
