I wonder what rodent pro feeds their rats. lol

Erin, I'll just tell you what I do. It may or may not be the best way, but it works for me and my 23 hungry scalekids. I keep one male to three females in large lab style cages. The females and male all stay together all the time. All the females help each other take care of their babies.. even the male will sometimes lay on them and keep them warm.

I wean babies at about a month, at which time males and females are separated out to their own grow out tubs.
