Cats and dogs cannot eat expired eggs. Eggs are rich in protein, which is good for cats and dogs. However, expired eggs may have deteriorated and contain a large number of bacteria. If cats and dogs eat expired eggs, they may cause diarrhea or even food poisoning, and in serious cases, they may endanger the lives of cats and dogs.

What should cats and dogs pay attention to when eating eggs:

1. It is recommended to cook eggs before giving them to cats and dogs. Salmonella is present in raw eggs, and eating raw eggs can cause vomiting and diarrhea for young, elderly, or dogs and cats who are in poor health.

2. Eggs have high nutritional value, but their nutritional content is not balanced. Cats and dogs can eat eggs, but they cannot use eggs as their staple food, and do not feed eggs every day. Feed them once or twice a week.

3. It is not recommended to feed protein to cats and dogs. Cats and dogs have delicate stomachs, and protein is difficult for them to digest and can easily lead to indigestion or diarrhea.
