I just bought two Russian dwarf hamsters on Sunday. I bought a male and female, the breeders that I bought them from breed lots of hamsters with different parent and are all kept separately so I don't know if my hamsters are siblings or not. My hamsters are only 6 weeks old now and I have put them in the same cage and they get on fine, I would like them to mate if they will I will not force them to mate but if it happens I will be delighted. Do you think I should risk them being related?
