I thought she just got fat because I always feed her on her favorite food, but I didn't really care that much since I got another fatter girl who just eats and sleeps. It was raining yesterday and I got back quite late. Actually it was my first time to work after 6pm, and I was really surprised to find that my little fat hamster had 5 little cute hamsters already. What a nice surprise! They are quite tiny without any hair, and their eyes are not open. All I can do right now is guarantee the mother has enough food, so that she won't eat her babies.
