Yep female rats can get preggie right away tho like Daniel said it's best to give them a bit of a break in between especially a good breeder that produces large healthy litters you want to not burn her out too fast.

Remember to seperate the litters by sex at around 5 weeks of age I think it is or the brothers will start bothering the sisters (or any other female they can get near....male rats are just....very....loving! LOL) How's that for keeping it PG.
