Cats can eat egg whites. Since cooked egg whites have no taste, most cats don’t like to eat them. If your own cats like to eat them, the breeder can feed them a quarter of the egg whites each time. Feed small amounts often. Cats who regularly consume boiled egg yolks can beautify and gloss their skin and hair. Breeders can feed them 1-2 times a week, and be careful to feed them fully cooked boiled eggs.
