No they will fight.
You shouldn't keep a dwarf in a cage.
Sanitize the cage and get new bedding and the cage is good as new!
you put it in the same cage with a male hamster
Yes unless another hamster has lived in it before. The best thing to do is to switch cages from time to time with your hamster if you buy a new cage. So he can get used to the newer cage while being in his or hers normal habitat. If you just want a hamster wonderland than i recomend buying another cage with some tubes to connect the cages.
no
I think so because I keep my hamster in the same cage I kept my last hamster in. I dont know for sure so ask a proffesional
NEVER put the new hamster in the same cage, with same stuff! BOIL the toys, cage, in warm, soapy water for 30 minutes! If you don't you are most likely to have another sick/dead hamster :( The disease might remain in the same cage where the sick hamster may have touched, nibbled or made any contact with. Stay safe!
yes, mine are both in the same cage
Yes. a boy hamster can be with a girl but i bet you they will have babies.
No.They will fight
That depends on the type of hamster.
It's not advised, no.
