How much apple for your cat?
Most guides say "a few pieces". Enter your cat's weight and get the actual daily ceiling, worked out from apple's calories and the 10%-of-daily-calories treat rule vets use.
Assumes a healthy, neutered adult at a stable weight, and that this is their only treat that day. Puppies, pregnant, very active or unwell pets need different amounts — ask your vet.
Why this verdict for cats
Plain apple flesh in tiny amounts is safe for cats. Skip the seeds and core.
Apple is one of the best fruit treats around — crunchy, hydrating, and rich in fiber and vitamins — for both dogs and cats, with one simple rule about the core.
How much is safe?
A few slices make a great low-calorie treat for a dog; a cat needs only a small piece. Remove the core and seeds (the seeds contain a trace of cyanide and aren't worth the risk), and cut into pieces to avoid choking, especially for small pets.
What happens if a cat eats too much?
Too much apple can cause a sugary upset stomach or loose stool; the core is a choking hazard and large amounts of seeds are best avoided.
How to serve it safely
Serve washed apple slices with the core and seeds removed; chill them for a refreshing summer treat, or mash a little into food. Skip apple products with added sugar.

Frequently asked questions
Can pets eat apple skin?
Yes — washed apple skin is fine and adds fiber; just lose the core and seeds.
Are apple seeds dangerous?
They contain trace cyanide; a stray seed won't hurt, but don't let your pet eat the core or lots of seeds.
