my hamster

Hi guess what hapened to my hamster, well Rorys hamster (Pips) started chasing my hamster (Sadie) around in their cage. Then Pips started biting at Sadies fur, poor Sadie. She has a bunch of sores on her now. So we decided to get another cage to seperate them. I think Sadie likes being alone. She loves to stash her food in the tunnel and sleep with it, and she tays up there all day long. She is a really lazy hamster.
