Hi

I would like to ask a question here.
I just purchased a Habitrail OVO dwarf hamster habitat for my little guys from PLC, is it sufficient for 2 winter pearl hamster?

Its been 7 hours since they been into it, and they are using the wheel quite well (i taped the holes on the wheel, hated them )

I am thinking about getting another habitrail cage (a proper square cage) to connect to this ovo. Is it necessary?
