Why Do Hamsters Bite?

Small cage

This is a big problem since many hamsters are kept in small cages. Hamsters need more space to feel comfortable and happy.

Teeth growing

Hamsters’ teeth never stop growing, so they must always chew and nibble on something.


Sometimes you’ll find your hamster biting due to stress. Living in a cage isn’t exciting for hamsters as they are curious creatures who like to explore the wild. It’s a confined space, which makes your hamsters feel stressed and anxious. Stressed hamsters express their emotions by biting whatever comes in their way.  

Hamsters want to keep their surroundings clean, and a dirty cage can make them anxious. Plus, it’s important to maintain a proper diet to prevent any psychological problems.

If your hamster stays stressed for a long time, it’ll start biting the cage. If your hamster bites aggressively on its cage, you should fix the problem immediately. The cage contains harmful metals and pain that can make your hamster sick. Excessive biting may also break your hamster’s teeth instead of filing them.

Depression and Boredom

Living in a tiny cage with no activities or toys can be depressing. Hamsters need enrichment activities and exciting toys to live happily. Additionally, loneliness and boredom also cause depression. Your little buddy may not handle tough emotions and start biting the cage.

Exploration can beat boredom for hamsters, but there’s not much to explore in a cage. So, you can install a hamster wheel in their cage. It’s a great activity for your furry friend. You can also introduce a variety of chew toys to curb their unwarranted biting behavior.
