You don't, unless you know the female is in heat and ready to mate. Otherwise keep them apart at any other time.
Do not put a female hamster with an already settled male hamster JUST DON'T
you shoudl not put a hamster and a guinea pig in the same cage no matter what.
Do not put the male around the female! Some male hamsters eat the babies, I'm not kidding.
All you have to do is put the male and the female into the same cage. But you should keep an eye on them for they may fight or mate.
You put a male and a female together.
you can never put them together because they will just keep fighting. if it is a dwarf hamster then you can put two female's together.
yes because they will have babbies
If you want them to breed, then yes if not then keep them separated
It is ususally a female hamster that attracts a male. If you want them together is suggest you have a piece of cardboard to seperate them if they fight. The male will sniff the female. if the female allows it then it is probably ok.
Yes.
A female hamster can get pregnant if it mates with a male hamster.
A female and a male female hamster must mate in order to create another hamster.
