thanks for the reply! I have done LOTS of research on mice (and I have had mice for over a year now) so this was my first breeding attempt. The babies will be either kept by me or housed by my many mouse-loving friends...so I am very excited that this is a possibility!
I have noticed her being very motherly to my new mouse Candice, and she has been a little bit less active than usually - more sleepy and less wall climbing on the cage bars. She is a big attention lover, so she cuddles up to me a lot still, but at times she is a little skittish and doesn't want to be held. But after a while she will come to my hand.
I'm not sure what else I can tell you yet. But if she is pregnant I calculated her due date to be around December 7th-10th, or possibly 12th.
and I will definitely post pics!
