Cats can eat eggs. Eggs are very nutritious for cats, providing high-quality protein, amino acids, omega-3 fatty acids, B vitamins, and vitamins A, D, and E, as well as a range of beneficial vitamins and minerals. Eating eggs in moderation can help cats grow healthily.

However, it's not recommended to feed cats only egg whites. Egg yolks are also high in cholesterol, which can easily lead to fatty liver disease and hyperlipidemia in cats. Eating egg whites can also cause diarrhea in cats, as they contain avidin, and excessive consumption can disrupt the structure of vitamin B in a cat's body. In general, cats can eat egg yolks in moderation, but they should not consume too much at once, and they must be thoroughly cooked.
