i am not sure what type of hamster it is, all i know is that is has lots of fur and is all fluffy... i have a male now, but once he dies i am thinking about 2 more i am trying to find out what gender though. but if it is ok to put two males, i might just get the male now... i just dont want fighting or breeding.
Probably 2 females because 2 males would fight with each other.
my new female killed my old one, maybe its best to get any two from same litter
