I recently purchased a dwarf hamster at Meijer about three weeks or so ago, and I just realized as i was cleaning her cage that there was a fair amount of blood on the packing shavings. I put some rubber gloves on and picked her up and there was a tubular, red, piece of flesh coming out her vagina. The whole rear end was bloody. I don't think she's pregnant, please help me, i don't know what to do.
