Since the old thread was really outdated, I cleaned it up, added a few ratteries I knew of, and formatted it better for the forums.

Please make sure you do your research when you visit these sites. This is, by no means, an "official" list of reputable breeders. Most of the sites are added based solely on their website information and occasionally information/experience from other users. Be sure to check out the Breeder Red Flags list before looking at any of these websites. Do your own research on ethical breeding standards beforehand and be sure the breeder you choose is up to these standards.

If you would like a rattery added, or if you see a problem with any of the ratteries on the list, please PM myself or another moderator. If you would like a rattery to be added, please include its name, location, website/contact information, and a short description to put on the post.
