Having a bar biting hamster is normal because a hamsters natural instinct is to chew on most anything they can get their teeth on.
The problem comes from excessive chewing on the bars of the cage which can wear down their teeth and cause so much noise it drives their humans crazy.
Getting a cage with no bars is the first thing you can do to stop the noise. A clear plastic cage or a cage with less bars and more plastic tubing for the hamster to climb around in is a good cage to get.
You might even think about getting a bigger hamster cage so your hamster has more to do inside the cage and forgets about biting on the bars.
Hamsters will gnaw on the cage bars a lot of times out of boredom, so if there are more things in their cage for them to explore or play with they are less likely to chew on the bars.
What Accessories Should Be Inside the Cage
The very first accessory that should be in the cage is a hamster wheel.
If you adopt a baby hamster you should buy two wheels, one small one for him while he’s little and a larger one for when he gets bigger and no longer fits in the small wheel.
Plus by the time he gets bigger he probably will have chewed a bit of the smaller wheel and it will be time to buy a replacement one anyway.
Other things to have in the cage are toys, chew blocks, mineral blocks, nesting box, food bowl, and small houses for him to climb in and out of. The more toys, houses and chew blocks you have for him to play with and chew on, the better. This will give him something to keep him occupied with and if he’s not bored, he won’t be inclined to chew on the bars.
Time out of the Cage
All hamsters need time out of their cage to play with their humans.
Some hamsters love getting out of their cage so much that they will start chewing on their cage bars as soon as they see you, letting you know they want to come out and play with you.
I had several hamsters that did this and would not go back to gnawing on the bars once I put them back in their cage after play time.
This time out of the cage also gets the hamster used to you handling them and handling them every day is a necessity if you want to be able to handle them without getting bitten. A scared, timid or unsocialized hamster is more likely to bite you when handled.
By following these simple steps you should be able to keep your hamster from chewing on the bars all night while you are trying to sleep.
