not as such.
most mice get very pregnant, and in the later stages you can see the babies
shifting around inside the mother.
feed her some protein, such as dry cat food, peanut butter (not too much), and
hard boiled egg. pregnancy is hard work and sometimes the mother will become
protein-starved.
after the babies are born be prepared after four weeks to separate the males
from the females into their own cages. if you can't tell them apart ask a pet
shop to help you.
