Answer
Hi there,

I don't think it sounds as though your hamster is pregnant, it does sound sick, and so i think you should take it to a vet as soon as possible, as early treatment is essential for survival.

Unfortunately i can not tell you what it maybe as there are several things that can cause changes to the bottom area, and so it will need an examination. It is however important that you make sure the hamster is eating and drinking, and you may have to encourage this by droppering water into the mouth slowly!!!

Hope this helps,
Hope your hamster gets better,
Thanks,
Charlie.
