Can cats eat apples?
Peeled flesh is fine in tiny amounts; seeds, stems and leaves contain cyanogenic compounds.
Portion: 1–2 small pieces, occasionally.
The short answer
Yes, a small piece of fresh apple flesh is a safe occasional treat. Peel it, core it and remove every seed. The ASPCA lists the apple plant (stems, leaves and seeds) as toxic to cats because it contains cyanogenic glycosides. A thumbnail-sized, seedless piece now and then is plenty. Skip apple sauce, pie and juice.
Why the verdict
Apple seeds, stems and leaves contain amygdalin, which releases cyanide as it's broken down. One or two swallowed seeds are unlikely to poison a cat, but the risk isn't worth taking and it adds up if a cat chews on the plant. The flesh itself is non-toxic, just sugary and fibrous, which is the usual cause of stomach upset.
How to prepare it
- Wash, peel and core. Remove every seed.
- Cut into pea-sized pieces.
- Fresh apple only: no sauce, pie, dried apple chips or juice.
- Keep apple branches and leaves away from cats that chew plants.
Signs of trouble
- Vomiting or diarrhoea
- Bright red gums, dilated pupils or laboured breathing (signs of cyanide exposure after chewing seeds, stems or leaves)
Apples & cats: FAQ
Are apple seeds poisonous to cats?
They contain amygdalin, which releases cyanide when chewed. Always remove them. A single swallowed seed is unlikely to cause harm, but call your vet if your cat has chewed several.
Can cats eat apple skin?
It isn't toxic, but it's tougher to digest and may carry pesticide residue. Peeling is kinder to the stomach.
Can cats eat applesauce?
Plain unsweetened applesauce in a tiny amount isn't toxic, but most brands add sugar or sweeteners. Fresh, peeled apple is better.
