Can Hamsters Eat Apples? Yes, Seeds Out, Small Pieces

Apple flesh is fine; the seeds come out

Apple is one of the easiest fruits to share with a hamster: firm, not too juicy, and easy to cut into small pieces. VCA says fruit can be given to rodents occasionally and in small amounts, and Merck agrees that small amounts of fruits can be given to hamsters.

The seeds and core are the part to remove. Lafeber, writing about pet birds, notes that apple seeds contain cyanide and should always be removed before feeding apple. For a hamster, which is far smaller than most pets, the same simple precaution applies: cut out the core and check every piece for seeds.

Why fruit stays occasional

VCA's guidance is that fresh vegetables can be offered daily, but fruit only occasionally. Fresh foods together should be no more than about 10 percent of the diet, with a high quality pelleted rodent chow making up about 90 percent.

Merck notes that digestive problems are common in hamsters, that diarrhea, often called wet tail, is seen often, and that diet changes make diarrhea more likely. Sweet fruit given often, or in big pieces, is one of those changes.

How to prepare apple

Wash the apple, cut a thin slice, and remove the core and every seed. Cut a piece about the size of your hamster's ear for a Syrian hamster, and smaller for a dwarf. The skin can stay on a washed apple; it is firm and gives the hamster something to chew.

Offer it by hand or in the food dish. Merck notes that hamsters often store food in their cheek pouches or hide it in the cage, so check hiding spots later and remove any browned or soft apple. Skip applesauce, apple juice, dried apple with added sugar, and apple pie.

Hamsters hoard food, so check the corners of their hamster cage for stashed fresh food every day; a large hamster cage with deep bedding makes those hidden stores easier to find.

How much and how often

Once or twice a week, a single ear-size piece is plenty for a Syrian hamster, and less for a dwarf. That keeps apple within VCA's guidance that treats total less than 5 to 10 percent of the daily diet.

Rotate apple with other occasional fruits, such as a single blueberry, and give vegetables the daily fresh-food slot. VCA lists leafy greens and yellow and orange vegetables, such as carrot and squash, as acceptable daily foods.

If your hamster ate apple seeds

If your hamster got hold of apple seeds or the core, remove anything left, including from its hiding spots, and call a veterinarian who treats small mammals for advice. Tell them roughly how many seeds may have been eaten.

If you cannot reach your vet, the ASPCA Animal Poison Control Center at (888) 426-4435 and Pet Poison Helpline at (855) 764-7661 can advise; a fee may apply. Watch for weakness, breathing difficulty, lethargy or refusal to eat, and get your hamster seen promptly if any appear.

Signs to watch and when to see a vet

Merck describes wet tail as wet fur around the tail, low energy, poor appetite and weight loss. If you see these signs, stop fruit and see a veterinarian who treats small mammals promptly; Merck warns that some antibiotics can be deadly to hamsters, so never medicate without a vet.

Also see a vet for a hamster with swollen cheeks that do not empty, overgrown teeth or weight loss.
