Can cats eat muskmelon?

Cats can eat muskmelon, but it is generally best to feed little or none. Although muskmelon contains plenty of water and vitamins, and moderate feeding can help cool a cat in hot weather and boost its nutrition and immunity, its sugar content is high, which easily adds to the digestive burden and may even cause abdominal pain and diarrhea.

Second, frequently giving cats muskmelon or other fruits and snacks can lead to picky eating, which over time may cause malnutrition.
