They can of couse be put together. after 4-5 weeks though they could possibly start breeding. around 6 weeks is when they may fight if they dislike eachother.
Yes. a boy hamster can be with a girl but i bet you they will have babies.
yes, mine are both in the same cage
NO
No, serious fighting will occur, they are very territorial
Teddy bear hamsters are Syrian, so don't put them in the same cage. But I have both types, boy and girl. They get along perfectly (though not in the same cage). Every hamster's personality is different. In the same cage- it may result in fighting and death. So be careful!
It is more than likely they will. Or they'll fight, maybe to the death.
They will probably fight. However, a dwarf hamster male can stay in the cage with the female. He can help raise the babies.
Get another cage?
Yes, if they are mature, they will fight to the death. However, they can live with each other when they are still babies. {This is why it is hard to breed hamsters.}
Yes until the girl gets pregnant then she will start fighting the boy so you will have to get him his own cage.
You can but there is a big big chance of them mating and having lots of kids
Unless the dwarf hamster was in the same litter, I would advise against it. If they are not in the same litter, and you'd like to see if they get along, first put them in a neutral cage. Otherwise the hamster may feel that another male is trying to take over its territory.
