Well my daughter has started to breed pet rats. She likes what they call the fuzzy hairless rats. They grow hair in spots or something like that I guess. She had seven babies recently 3.4 is the break down. She is going to keep one female and sell the rest off. Since the mom of this litter took the dad out before they were born, she will be starting to use my hairless pet rat "Jack" for stud service with her two girls now. This is the one she is going to keep. Most of the fuzz should fall out as she grows. She is 3 weeks 3 days in this picture.
