Q. Why is so much emphasis put on protein in cat foods?
A. Cats require more protein in their diets than do dogs. Cats break down dietary protein to provide themselves with the amino acids they need to build proteins within their own bodies(e.g., muscle cells and enzymes). A cat's body can convert some amino acids into others. These are called non-essential amino acids because they do not have to be supplied directly by the diet. On the other hand, essential amino acids do need to be included in a cat's food because the feline body is incapable of making them. Taurine is an example of an essential amino acid for cats.
