Mice/Mice keep moving babies


QUESTION: I bought 5 pet store mice a 2 white ones, a black one and 2 brown ones. apparently one of the white ones was a boy, one of the brown ones had babies about a week and half ago the other brown one just had hers last night and the white one looks like she is gonna pop any minute, but the little black one keeps moving the newest babies out of the "main" nest and into their second house (1 house not enough for 4 mice) but the white one who is still pregnant keeps moving them back, I just wanted to know if there could be any problems from them moving the babies so much. I have the black one separated from the rest while I go to work just because I dont want to have any problems happen while I am at work. And yes the male now has his own tank.

ANSWER: Dear Randy,

Three litters is a lot for one cage. If there were only two my advice would be there out to be one big house/shelter/nest and no place else to sleep. But three? I would put the black mouse and the white mouse in another cage together, with only one obvious nest. This way also, the younger babies of the last litter will not be pushed away from the teats by the older pups. And the black one should be a happy aunt, since she obviously wants to be!!

I have answered questions about raising babies and rehoming them as well. If you can't find what you need, write back.

QUESTION: Ok got home and the white one has already had her babies. Should I move the larger litter? or just leave them all in there? and the cage has the same dimensions as a 50G aquarium. Is that enough space for all of them? or should i still move some of them.


It is big enough for all three litters, true.

I am not exactly sure how you it is divided between the two houses. Of course if the black one has stopped moving the babies everything is all set.

Otherwise could you please describe  which litters are where so I can help try to sort it out?

I can answer questions about raising mice and caring for them as pets, with knowledge from my 38 years of having fancy mice as pets. I have NO MEDICAL TRAINING and you should take a sick mouse to the vet; but if you simply can't, I will try to help you. I LOVE PHOTOS!!! I ALSO LOVE UPDATES! Let me know how the little tyke is doing later on, for better or worse, especially orphans. It also helps me to help the next person. Please first search first: use 'Natasha Mice Mouse' with whatever else your question includes. Or check out these links: **** YOUR FIRST MOUSE (my video; rough draft): **** TEN VIDEOS ON RAISING ORPHANS: **** SEXING MICE: **** And some GREAT MOUSE INFO SITES:


I have had mice for 40 years (since I was 5!). I raised them when I was a child but now I keep all females, and never fewer than three so that if one dies the others are not devastated, because they have each other.
