Cats eat all kinds of food! Cats are usually carnivorous. They should eat fully tested cat food and should get a veterinarian to help choose what cat food the cat should have(moist/dry). Cats should not eat bones, leftover foods, chocolate, or drink milk, although they like drinking it. Instead, they should always have a bowl of clean water to drink. Cats also like snacks, such as tuna, shrimp, and usually catnip.
