Can Cats Eat Watermelon?
Short answer: Healthy cats can have a small amount of seedless watermelon flesh as an occasional treat. Skip the rind and seeds, and avoid it for diabetic or overweight cats.
Why it’s okay
PetMD (written by a veterinarian) calls watermelon generally safe without seeds or rind, but notes it offers very limited benefit because cats are obligate carnivores. It contains natural sugar and carbohydrates, so overweight and diabetic cats should avoid it.
How much and how to serve it
A single 1-inch cube, cut into bite-sized pieces, is typically enough for a healthy cat, as an occasional treat only.
Risks to watch for
- Seeds contain trace cyanide and can be a choking hazard.
- The rind is hard to digest and can cause choking or digestive problems.
- Some cats get vomiting or diarrhea even after small amounts.
What to do if your cat ate watermelon
A little extra usually causes nothing worse than an upset stomach. If your cat ate a large amount, has vomiting or diarrhea, or seems unwell, call your vet.
