The "inquires and feedback" section isn't a list exactly, but it is an excellent place to look to see if a breeder is trustworthy or not, has healthy, quality animals, etc. Plus, if you are considering a particular breeder but can't find feedback on them, you can post an inquiry there and usually you'll get replies from other people who have dealt with them.
