Well, I have petstore stock. I was going to get some breeders from Rysratties, but she dropped out and went into rescue apparantly. Funny though, I see your post about her, lol. The other thing about her was the fact that she was breeding TRUE hairless females, and loosing entire litters. I can understand breeding a hairless female and using a wet nurse female to raise the litter, but, with all of the issues that true hairless rats have, there's just no point in even trying to breed a hairless female and allowing her to attempt to raise the litter. Plus the fact that some of her rats, she was unsure about genetics, like, she didn't know if they were true hairless or double rex.
I've BEEN wanting to find more true hairless rats though, for my own purposes, but, most breeders won't sell a rat if they know that you have snakes and intend to cull off extras. Same with most of the other varieties. So, it's just easier on me to get healthy petstore stock.
Either way, I have only unknown lines, but if you'd like some, you're more than welcome to them. I have one girl who is a total biotch, but she has been producing excellent litters (usually has more than 20) and they always turn out to be the sweetest babies, lol. I haven't had any health issues with these guys either, despite doing "unethical" breeding, such as breeding unknown lines of highwhites. I don't breed to sell to anyone else for pets, but they do all seem to be better pets than some of the ones that I've picked up from "ethical and reputable" breeders, if you don't count the one nasty female, lol.
