Can Cats Eat Apples? Seeds, Core and Safe Serving Tips
An apple a day may be a saying for people, but cats have different needs. Apples are not poisonous to cats in the way grapes or onions are, yet they are not an ideal snack either. The parts that need care are the seeds, the core and the products made from apples.
What apples contain
A medium apple has about 95 calories, mostly sugar, with fiber, vitamin C and a variety of plant compounds. It is about 85 percent water. Cats make their own vitamin C and cannot taste sweetness, so the fruit offers almost nothing they do not already get from a complete food. The fiber can help or hinder digestion depending on the animal, and in cats it can cause loose stool if given in excess.
The seeds and core
Apple seeds contain amygdalin, a compound that releases hydrogen cyanide when seeds are crushed or chewed. The quantity in a few seeds is small, and a cat would need to chew many to be at risk, but there is no reason to take chances. Seeds can also cause choking or blockage in a small animal. Always remove the core, seeds and stem before giving apple.
Quick reference

How to serve apple
- Wash the apple and peel it, since skin is tough and may carry pesticide residue.
- Cut out the core, seeds and stem completely.
- Cut a piece the size of a pea.
- Offer it by hand and watch your cat's response.
- Do not repeat more than once or twice a week.
Keep treats to about 10 percent of daily calories. Our cat food amount calculator helps you plan.
Hard cider and other drinks
Alcohol is dangerous for cats. Even small amounts can cause vomiting, weakness and low body temperature. Never allow a cat to lap cider or cocktails. See is alcohol dangerous for cats.
When to skip apples
- Diabetic cats. Ask your vet before offering fruit.
- Overweight cats. Fruit calories add up with other treats.
- Cats with sensitive stomachs. Apple fiber can cause loose stool.
- Cats with kidney disease. Ask your vet about any new foods.
- Kittens. They need complete kitten food. See our kitten feeding schedule.
Signs of a problem
If your cat swallows seeds or a piece of core, watch for vomiting, drooling, difficulty breathing, wobbling or bright red gums, and call a vet or poison helpline at once if any appear. For milder upset, expect loose stool or gas that settles in a day. Our emergency warning signs guide lists signs that mean you should act quickly, and our US vet directory helps you find care.
Myths about apples and cats
"Apples clean cats' teeth." Cats do not chew crunchy foods in a way that scrapes teeth, and dental disease needs proper care. See our cat care guides.
"Apples help hairballs." Fiber in small pieces will not reliably prevent hairballs. Regular brushing is more effective. See how to brush a cat.
"A cat that nibbles apple needs vitamins." A cat that suddenly seeks plant material may be bored, nauseated or missing something in the diet, and a vet can help work it out.
Dental health and crunchy foods
Many owners hope that crunchy foods will clean teeth. In reality, cats chew little and swallow most food in pieces, so an apple slice will not remove plaque. Dental disease is one of the most common problems in cats, and prevention rests on regular brushing, veterinary dental checks and, when recommended, professional cleanings. Our cat care guides cover home routines.
Cinnamon, nutmeg and other apple spices
Apples often appear in spiced dishes. Nutmeg can be toxic to pets in larger amounts, causing disorientation, rapid heart rate and tremors. Cinnamon in small amounts is usually not dangerous, but cinnamon essential oil and potpourri can irritate the mouth and are risky. Keep baked apple dishes, spice jars and simmering potpourri out of your cat's reach.
Quick safety checklist
- Is the apple peeled, with every seed, the core and the stem removed?
- Is the piece pea-sized and soft enough to swallow safely?
- Is there no sugar, spice, alcohol or sweetener involved?
- Does your cat have diabetes, kidney disease or a sensitive stomach?
If all answers are yes, a single piece is a harmless novelty.
Better treats
Meaty treats such as plain cooked chicken suit a carnivore better. For other foods, use the free cat food and plant safety checker, and ask your veterinarian if you are unsure.
Frequently asked questions
Are apples safe for cats?
Small pieces of plain, peeled flesh are generally safe, but the seeds, core and stem are not.
Are apple seeds poisonous to cats?
They contain a compound that can release cyanide when chewed. A few seeds are unlikely to cause problems in a cat, but they should still be avoided.
Can cats eat applesauce?
Only plain unsweetened sauce in tiny amounts, and it is better to skip it because of the sugar and cinnamon in many products.
Why does my cat like apples?
Most do not. A cat that chews apple may be after the crunch or the texture.
