I also have a wheel obsessed baby syrian too. She seems to have two main settings - running or sleeping
I assume it's baby hamster manic energy but it could just be her personality type
She seems to wee and poo whilst running too. Her wheel is lined with cork so I'm not sure how I'm meant to clean it effectively..
Other than it being a little frustrating for me wanting to get to know her better, i'm not too worried about her.
Sorry not to have been more helpful
Hope he chills in time!
