Fancy mice at the store I live near are $3.99 and feeders are only $0.99. I have fifteen mice, and all of them came from one female. They were rescues, some 14 yr old thought it was funny to let terrified mice out. In the CAFETERIA. So we rescued them, and lol we had no idea she was pregnant, then she got bigger and had babies while we went out for dinner. LOL it was so suprising. Now the babies are full grown, they were born in June. (I think)
