Quince is slightly riskier than apples for cats. While both are safe in small amounts when cooked, quince seeds contain cyanogenic compounds that can be harmful if crushed or chewed. Stick to peeled, cooked flesh of either fruit and avoid the seeds. If your cat eats quince seeds or shows signs like drooling or vomiting, call your vet.
