Cats can eat egg whites. Egg whites contain high-quality protein, which can effectively supplement the protein needs of cats. For adult cats with good digestive systems, eating a little egg white may be fine, but it needs to be mixed with other foods. Otherwise, the cat may not eat it. Egg white should not be fed to cats for a long time, as it can easily lead to anorexia in cats.

Cats develop their own eating habits when they are young. If you only feed your cat cat food, it may only eat cat food when it grows up. If you feed your cat as much food as possible when it is young, it will be more accepting of a wider variety of foods when it grows up.
