Shun! lolol jk.
I think you have breeders confused with whole salers... That's a whole other beast to tackle in a discussion forum..
I have yet to see a breeder who didn't take good enough care of their animals who are also successfully producing offspring.
I HAVE seen several local shops where I will NEVER bring ANY of my animals near.. Poor lizards with mouth rot and IBD... Multiple species of snakes housed together competing for the same small water bowl because they have mites all over 'em... Not all the local shops are like this, but they DO exist.. They don't prey only on ball pythons either. Nile monitors, savannah monitors, various lizards, fish, and even mammals.
