I currently have a rat breeding operation going. I have 4 proven females, two males 1 proven, and three unproven females. I say proven and unproven because i used to breed mice and have had some duds on both ends lol. For my current collection of 17 bp's this is obviously not enough as they will pound through a litter and a half a week! Anyone have a good balanced ratio of snakes to rats going. I try to feed at least once a week.
