boy rabbits sould not live together but if you introduce them when at least one of them are under 4 to5 months it is easyer to get them used to each other
girl an boy rabbits do not look the same
yes but the girl will get pregnant.
If they're spayed / neutered, yes.
yes, mine are both in the same cage
No, serious fighting will occur, they are very territorial
Word of advice, NEVER put two boy hamsters in the same cage. Just putting two in separate cages next to each other can be dangerous.
NO
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 and the longer they get the chance the more rabbits you will find are having babies. If you put 2 boy rabbits together they cannot have babies together. Only if a boy rabbit is in the same cage as a girl rabbit. In some countries having many babies very quickly is called breeding like rabbitsSibling rabbits that breed together will have an increased likelihood of having kits with birth defects and other problems. The more they are inbred he worse this problem becomes.
No
I have two male hamsters they have been in the same cage alone numerous times, and they do not fight ever.
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.
