Things You'll Need
Cats need a high protein and low carbohydrate diet. A diet with the necessary amino acids, fiber, carbohydrates and fatty acids can help your cat's energy level, digestive system and overall appearance and health. Liver has iron, copper and magnesium, important components of a feline diet. Also, most cats love liver. If you want to cook up the livers, you can feed them to your cat in a number of ways.
Boil the livers by placing them in a pot of boiling water. Grate the cooked livers for an older cat who doesn't have teeth. Older cats or cats who have had gum disease may not have teeth, but they can live happily by eating finely cut or grated foods, which they swallow whole.
Grate the cooked livers into your cat's regular dry food if you want to give the cat's regular dry food a nutritional boost. Some cat-care experts believe that dry food has a carbohydrate level that's too high for good cat nutrition. You add some grated chicken livers to increase the protein level and lower the carbohydrate level of your cat's food.
Use the liquid from boiled livers to feed a cat on a liquid diet. Sick or badly injured cats may have difficulty keeping down solid foods. You can put the broth from the boiled livers into a baby bottle and feed the cat. You should feed the broth to the cat several times a day in small quantities until the cat can start eating again on its own.
