Cats can eat peanuts. Peanuts are rich in fatty acids and vitamins, which can supplement a cat's nutrition and clean its mouth, preventing bad breath. However, they should not eat too many. Cats have delicate digestive systems, and feeding them too many peanuts can be difficult to digest, easily leading to diarrhea, vomiting, and other adverse symptoms. Therefore, cats should not be fed too many peanuts at once. 
Precautions for cats eating peanuts:
1. Owners can cook peanuts before feeding them to their cats. Cooked peanuts are easy to digest and will not irritate the cat's stomach.
2. Do not add any seasonings during the cooking process of peanuts, so as not to increase the burden on the kidneys and affect the cat's health.
3. You can crush the peanuts before feeding them to your cat to prevent whole peanuts from getting stuck in its esophagus.
