A home cooked diet is another option for your cat. While making your cat's food would allow you to know exactly what is in every piece of food that he eats, formulating your own cat food can be a very confusing process. It is very difficult to make sure your cat is getting all of the nutrients he needs if you make your own food. Even if the food you make includes all of the right nutrients, they may not be in the correct quantities or the proportions may be off. Because of these difficulties, it is usually recommended that cats are fed commerical foods, unless otherwise specified by a veterinarian. Some veterinarians supply recipes for home-cooked cat foods, especially for cats suffering from particular diseases, allergies, etc.
