New Syrian Hamster

Question
I recently bought a Syrian hamster from a pet store. She's 2-3 months old, and was placed in an all male cage (the pet store was supposed to have only male, but she was mixed in). When we first got her, she bit my boyfriend a few times. Now, she's better because she's more tame. We've  noticed that she sleeps all day, and all night. when we wake her up however, she's very active and normal. She also goes to the bathroom a lot. She's been digging a lot, and whenever we feed her, she empties out her dish and carries it into her wooden house. She also stays in the house all the time, even when she's awake. We were wondering, do you think she's pregnant? We've have her for 5 days, and can't really notice if she's gained weight. We also can't feel nipples to tell that way.

Thanks,

Hi,

There is a possibly that she could be pregnant. They tend to get larger during the last few days of pregnancy but not always. They will usually spend quite a while making nests and hoarding food. If you need anymore help then I have a page about breeding here: http://www.hamsterheaven.co.uk/breeding.html
