How old is too old for a mouse to breed for the first time? Mine is just under 4 months now and we are expecting her first litter and I'm worried about her. She has been showing (the golf ball in her stomach) for about a week now. On monday we saw this for the first time and around 2 days ago she stopped getting bigger. She is a pet, who is breeding feeders and we really love her. Is it taking too long for her to give birth? Should I do anything if she has not given birth by monday? Thanks a lot for all your help.
