The reasons why hamsters bite the cage:

1. To grind teeth, be careful to prepare some teeth grinding tools for hamsters.

2. If you want to come out to play, it is best to let the hamster out and move freely for a while.

3. Lack of trace elements.

4. The estrus period has arrived.

5. Want to eat.

6. The cage is too dirty and the hamster cannot tolerate it.

How to stop a hamster from biting the cage:

1. Give the hamster hard food. In all likelihood, hamsters bite the cage because their teeth are relatively long and they need to grind them. At this time, the host has to consider whether the food given is too soft. In particular, owners who feed their hamsters an omnivorous diet need to check their hamster's teeth and add hard food, such as nuts.

2. Cut the rat’s teeth. If your hamster's teeth are already relatively long, grinding them won't solve the problem. At this time, you should consider shortening the hamster's teeth, otherwise the excessively long teeth will cause the hamster to be unable to eat and starve to death.

3. Hamster toys can grind teeth. There are a variety of hamster toys (such as teething snacks, teething sticks, teething toys, etc.) on the market that can effectively help hamsters grind their teeth.
