How can you tell early if Chinese hamsters are pregnant?

[Morphius]

We bought two Chinese "dwarf" hamsters from P@H about a week ago, and one of em (maggie) has grown quite a bit more than the other one (thatch). We aren't sure if she is just growing faster or if P@H (as often heard of) have messed up sexes again...

Cheers...

P.s. you lot wanted to know their names we finally came up with Maggie and Thatch

Males are pretty obvious in the Chinese hamster Did you notice any males in the tank? You can usually see a bulge appearing on the tummy in front of the hind legs but this sometimes does not show till nearer birth. Sometimes you get behaviour changes such as nesting and cage trashing early when the hormones kick in. She may just be naturally larger, not be from the same litter and be older or be hogging the food and eating more than her sister so make sure you scatter food all over the cage. It would be an idea to treat her as if she were pregnant and feed plenty protein.

Had a look at both of ours and both are definitely girls, not 100% sure about the rest of the tank, I suppose only time will tell
