Reasons a Hamster May Bite


This may seem like a broad category, but we’ll use the word ‘aggression’ here to mean fighting with other hamsters. Certain breeds, such as Syrian hamsters, can be antisocial and territorial by nature, and if provoked, they may try to take a bite out of the threat to their territory. To avoid this, if you have more than one hamster, it is ideal to keep them in separate cages.

Medical Conditions

If your hamster is injured, they may bite in order to defend themselves, just as they would do in order to protect an injury if they were in the wild. So prior to trying to handle your hamster, take a minute to observe them for a limp or any sort of injury.

Occasionally, certain disorders and diseases may cause hamsters to bite, including mange and rabies. If your hamster appears uninjured but displays sudden and intense aggression, contact your veterinarian for their perspective and assistance in properly diagnosing and treating your furry friend.

Handle your hamster with care until they get used to your presence and their surroundings. And even after they are used to you, always be gentle with your furry friend. If they get handled too roughly, they may bite out of that same fear instinct for self defense.

Another way to spook your hamster is to jar them awake. Hamsters are mostly active at night, so if you try to pick them up during the daytime when they’re trying to snooze, they may have a nip at you because they are disoriented. Always try to handle your hamster when it’s awake.
