Cats can eat many fruits, such as apples, bananas, strawberries, pineapples, watermelons, cantaloupes, and blueberries. However, you shouldn't feed them too much, otherwise it may cause them to have diarrhea. 
Do not feed cats too much fruit. It's best to wait at least half an hour between fruit and regular meals to avoid affecting digestion and absorption. Fruit is not recommended for obese cats. Also, fruit seeds contain cyanide, so do not feed cats the pits or seeds.
Giving cats fruit in moderation can provide them with vitamins and promote intestinal motility. It can also help cats that don't like to drink water to stay hydrated. However, for cats with sensitive stomachs, it's recommended to feed them fruit sparingly.
