Hi, was wondering if anyone could give me there opinion on whether my rat could be pregnant? I got Storm 10 days ago. When we got her she was slightly smaller than the rat we already have (both rats are female) but the last 2 days we've noticed Storm has started to get a bit of a podgy belly which you can only really notice from the front when she's climbing up the cage. Saying that when she isn't climbing you can tell she's put a bit of weight on around her back/rump area (but not overly). I've only just been able to weigh them today and both rats are around 165 grams so just from that and the way Storm looked when we 1st got her we know she's put on a bit of weight (as I said she was smaller then my other rat). I'm not sure though whether the weight gain is because she is eating a lot more now then before we got her as beforehand she was kept in a cage with quite a lot of other rats so don't know if she would have had access to enough food there. So really what I want to know is how far along in a rats pregnancy can you definitely tell she's pregnant and should I weigh her everyday? I would be grateful for any advice, thanks.
