Not the first time I've heard of that. I appreciate a breeder who cares enough about the future care of their snakes to bother.
I don't know the stats. for what happens to most pet snakes, but I'd bet they are not encouraging.
Hardly condescending. Have you looked at the sales contracts many pure bred puppy breeders require? And, those contracts are lenient compared to what many dog rescues ask for. I find the rescue contracts impossible (those often ARE condescending).
