Hahaha... looks like chewing gum on the rocks...
Cute Roborovski hamster... I used to keep them. Unfortunately, nice to watch, but no fun to play. Way too fast, these fellas. In my previous company, my boss was given a hamster, and she kept it in the office. Under air-con environment, the fur grew so thick it was like a fur ball. Very nice. If you pamper them, buy a mini fan and hook it up. They should develop a nice coat of fur.
