"i bought this for two dwarf hamsters. at first it was way too big for them and they were just scared of the whole thing. but then i just put the box behind the main living quarters. then instead of the tubes going up, they go back at an angle. now it's not too steep for them to climb around. i'll have to come up with a more fashionable look for the setup but overall, this is the best habitat i've seen. plus it looks really cool and they seem to be happy.
the only downside is that the wheel is too big for them. i'm going to give it a few more days to see if they just need to adapt. otherwise i'll take the stairs out and get a smaller wheel."
