Watermelon is hydrating due to its high water content and can be a refreshing treat for cats.
Risks
Too much watermelon can cause digestive upset due to its high fiber content.
Seeds contain cyanide and can be toxic in significant amounts and also present a choking hazard.
The rind is difficult to digest and can also be a choking hazard.
Suggestions
Feed watermelon to cats only occasionally and in small, bite-sized pieces.
Ensure all seeds and rind are removed before offering it to your cat.
Note: even if labeled as safe, any food can potentially cause allergies. When introducing a new food, please feed a small amount and observe your cat for any allergic reactions.
