Do you separate pregnant mice?

[Brandon Osborne]

Why wear the females out if you don't have to? It's not going to hurt to give mice a break, which most will argue prolongs the breeding life of the rodents anyways, plus you can produce healthier stock without overbreeding everyone.

Says who? How is healthier stock achieved with less breeding? They all wear out around the same age. They have a peak production age and once the peak is hit, they taper off until they die. Keep them long enough and you'll see. I only speak from experience.....and some of that experience comes from the largest rodent supplier in the U.S. I'm not trying to be harsh, I'm just trying to make things easier for some of you. Oh well. Do what is best for you and you'll be fine.
