Thank you so much for your help

Hi, I recently adopted a winter white named Taro. He shows the same biting behavior. Later on, I do more observations on him and figured he has diabetes, which is the reason behind all the bitting. (He also drink a lot of water, pee a lot, and his cage smell very sweet)
There are many other reasons for his behavior. You should pay more attention and see what other behavior that he has.
Hope this help!
