How many times can a roborovski hamster get pregnant?

You never know for sure... my hamster actually just had her second set of pups. The first time she had two (They don't have many the first time they give birth) and just 12 days ago she had 7 more. If you think yours may be pregnant give it food with a lot of water and keep it healthy before and after birth. And if she does have babies, Remove the dad from the cage. Boy hamsters are territorial and mine attacked the new born babies. But yeah, your hamster may have any number of babies.. 2 at the least, & probably no more than 9 or 10.
