Is my Mouse getting ready to have babies?
I got 2 female mice 2 1/2 weeks ago tomorrow. One of the mice looked chubby when we got them home and I have been keeping an eye on her but she hasn't changed in her appearance where she would be obviously pregnant. I've read that mice have a gestation period of up to 21 days and I figured she must not be pregnant since she hadn't had babies or shown any signs that she was about to have babies, however this morning her behavior is different. She is wide awake and she was literally jumping straight up in the air. I also noticed that she is taking her bedding and shoving it in her igloo. Does this mean that she is making a nest and is about to have babies or is this a false nest? I cleaned the cage just in case, is there anything else anyone would suggest? Also, if you think she's going to have babies, do you know when I should expect her to have them with the signs that she is showing? Thanks in advance for any suggestions or advice.
