i got my breeders from the petshop i work at part time . we have a customer that breeds fancy rats and brings us a lot of them . i pick through them and get the best looking out of the bunch . at this point i am starting to pull females out of my own breeding colonies for future colonies . the males i still look thru our feeders for unusual lookin critters . i always try to use unrelated males with my own females . yesterday we got a real nice himilain(sp) in but my boss beat me to him i did beat him to a nice siamese though
