You could try it, but, they have small litters, and cannibalism is high in dwarves. Plus the fact that they're nastly little buggers. I've had problems with dangling dwarves when I tried to play with friends' dwarves, they bite and don't let go half of the time. One plus to hamsters is that they cannot jump (they hop, and very poorly) so if there is no risk of knocking cages over, you don't need any type of top. The dwarves are very prolific, if conditions are perfect. They breed like mice, but you have a better chance of litter survival if you leave females with the colony. The males will actually help raise the litters, and will breed the females right after birth (thank god you're not a rodent). They don't get very big though, and you might worry about any junk in their cheeks when feeding to a snake. If you want to try it, I'd set up a male with however many females that you can (no more than say 5) and basically leave them alone, let them do their thing. If I remember correctly, the gestation is around 21 days, and weaning takes about the same amount of time.
