The nutritional intake of your cat is perhaps the single most important aspect in its health and happiness. It's significant to remember cats, despite many centuries of domestication, are carnivores and require meat. There can be no such thing as a vegetarian feline.
Cats have a particularly high requirement for protein.
Their preference for high-protein food is not a behavioral trait, or taste issue, but a biological imperative. Unlike dogs or humans, a cat requires a diet containing a great deal of fat. A well-balanced diet for a cat would consist of many things such as protein, bones for calcium, fats, starches, sugars, fiber, and vitamins. Here are some guidelines for feeding your cat human food. Cats can find tuna or liver, for example, very tasty and refuse to eat anything else.
