WHat I was thinking of doing was keeping one male in a 10, and hten have a female in a 10 when her babies are wenned Ill put them in thier own 10 and then seperate the sexes into 2 different 10. Or if thier are any tubs like the one showed on the link but smaller. My main consern is the rats chewing through the tub and getting out. If that happend you wouldent see me on the fourms anymore because my parents killed me.
