A nice idea, although does anyone else notice how old that water looks, or the sawdust going all over the desk? I hope that's not the guys lunch sitting right in front of the cage!
The guys over at nogerms would freak if they saw this :)
Edited to add: I've been informed that this is not an appropriate cage for a hamster so please do not make this mod for a live animal. Maybe a dolls house, or a make-your-own-cubicle for your dilbert cutouts, but not for hamsters. K, everyone clear on that?
