Yeah, hamsters are pretty much all fur, and as for their gestation period, it's just a little less than 3 weeks, prolly about 20 days, give or take.
If you got a rapid cycler you may get your time down to 18 days, but I doubt you'll get down to 2 weeks. In all honesty I suspect their gestation period is the same as mice, but the male dwarf hamster will immediately mate with the female, most times before she's even done having all the babies!! It's disconcerting the first time you see them mating so you assume she's done, then she has more babies. Something just isn't right about that, but it's just their evil nature. Since they have less babies per litter I don't see any reward, and I had them for years trying my best to refine it and make it work. The males really beat up the females bad sometimes when they mate, and sometimes you won't get babies out of them for months, it's really inconsistant.
