Watermelon flesh is 92% water and a safe, hydrating treat for cats. It contains vitamins A, B6, and C. The seeds and rind should be removed. Seedless varieties are easiest. Cats may or may not be interested in fruit, but watermelon is safe in small amounts.
Symptoms to watch for
- • GI upset from seeds or rind
- • diarrhea in excess
What to do
Remove all seeds and the rind. Offer flesh only in small pieces.
