[Hammymad]

I don't have any experience with keeping dwarf hammies together,they can live happily in a group/pair etc and they can be happy on their own.I got Rambo about 18 months ago frm being 8 weeks old and he's always been by himself and very happy.
My latest dwarf ham BB was a rescue ham and was bullied and attacked by her litter mates,so needed to be by herself.
If hams are from the same litter they've got a good chance of living together and being happy (there are a good few members Kyrillion for example who is much more experienced with keeping groups together) I'm sure she could better advise you on that.

The cages are too small, we aren't trying to tell you what to do,it's just much better for the hams if they have more space.and if you do end up getting a couple of hams- the more space the better I'd say.
