How do you mate dwarf hamsters?

To mate your dwarf hamsters, you have to have one female and one male hamster.

Make sure they have separate cages, and when your female hamster is "in the heat",

(hamster period, this means she's ready to mate) put them together in one cage for a few minutes. Observe. If they start fighting or biting each other, separate them immediately! Try again a few days later. If they like each other, they will mate and do their job. Leave them in there until they're done, or about half an hour later. Hope this helped!

P.S Female hamsters are in the heat every 4 days, and to tell if she is in the heat, just tickle her bottom and she will become stiff and in an awkward position, she will also smell very odd.
