I'm not breeding Quetzal (most likely), but I just wanted to point out that in the dog world, the purebreds with health issues are dogs that were not bred by reputable breeders. Those with genetic health issues, bad temperaments, and don't fit standard in terms of color or structure are "humanely culled" by speutering. Unfortanately you can't neuter a snake or garentee that the new owner will never breed the snake, and snakes themselves don't have such strict standards on what is considered good breeding stock. So either snake owners crack down and do some strict self regulating and adopt all the lovely (ick) politics of the dog breeding world or it'll all remain up to a person's personal judgement.
