Is this a change in behavior? If so then an appointment with your veterinarian soon would be recommended as he could be in pain for even sometime like a brain tumor causing behavior changes. However, if this is a newly acquired hamster then this may be his personality. On average hamsters are usually more aggressive and less docile then other pocket pets. This is usually not something that you can train out of them. Best of luck and thank you for using Pet Coach.
