How can I stop my hamster from chewing the bars of his cage?
My hamster is notorious for chewing on the bars of hus cage and it keeps me up at night. I've tried wooden chew toys, watching his feeding habits in case he's hungry and a whole bunch of other stuff. Is there maybe some substance that's bitter but not harmful that I can put on the bars to deter him from chewing? Or some kind of incentive to get him to run in his wheel if it's because he's bored?
