I think a lot of the sub-par animals are also caused by people buying from local pet stores rather then from bigger and more reputable breeds or stores and then going home and thinking they can breed them. I know of breeders in my area that sell their seasons left overs to pet stores because they are lower quality and are unable to sell them to hobbyists because of it. Granted, I bought my first ball python from a pet store but I got lucky and she was from a breeder who had to get rid of his collection and the pet store had all paperwork and genetics for her.
