my spider I just rescued off craigslist is a perfectly healthy snake albeit he does this thing were if he misses a strike he turns his head upside down lol.
With responsible breeding comes the jackwagons who do the good ol' backyard breeding projects, produce WAY too many animals and don't care for them. Its a give and take in the hobby. I love the idea of finding new morphs, but as responsible breeders its everyone's job to determine if a morph has inherent health risks and make it known. BPs on a whole really don't suffer major detrimental health defects due to morph breeding, except some are known for kinking or the wobbles.
