we have today bought two young dwarf hamsters, having had (single) syrians in the past. One of them is very confident, has started exploring and is right now very active, trotting about, using the wheel etc. he's a round shape, really beautiful. The other, his brother i believe, has just stayed in one corner since we came home, eyes wide open, staring at me in horror. on the single occasion he's walked around he's a longer, thinner shape and his central dark line down his back does not run symmetrically down his length. I've held him and he's been able to run around me, climb on my shoulders etc, behaved as other hamsters have. So. is is likely that the other is just dominant? or (as i'm fearing) is the quiet one in some way a less robust specimen?
I realise i could take it back to the shop but...i'm kind of already in love with them. just don't want a sad hammy.
