If putting your mice and rats is the same room is wrong, I don't want to be right.
Actually contray to popular belief, I hear this all the time. I have my rats and mice in the same area in the mouse house. Since introducing the rats into the enviroment I have noticed a decrease in mouse production. And in nature rats will eat mice and raid their nest... So there may be some basis for this theory.
However, now saying this, the mice and rats still breed and show very little signs of stress. Go figure....
