My cat nibbled on a piece of watermelon rind — should I be concerned?

The rind itself isn't toxic, but it's a choking hazard and can cause intestinal blockage, so you should be watchful. Seedless watermelon flesh in small, bite-sized pieces is a safe, hydrating treat for cats. Always remove all seeds and the tough green rind before offering any. Monitor your cat for the next 24 hours for signs of gagging, vomiting, or lethargy, and contact your vet if you notice anything unusual.
