[Snaky]

Well, let me add my 2 cents. For the record, I've never bought from Bob and so I cannot judge the health of his animals.

From what I've heard of several people, it appears that he plunders a den to make profit from it. That point alone would never make me buy a single snake from him. Why?
-Somebody doing something like that, I don't see him treating all those snakes he got from the den like he should do ( food, temperature, hiding places, humidity, ... ). Providing them with everything they need and making sure they are and stay healthy. Still this remains speculation, but it would greatly surprise me if he did.
-Telling everybody that it's all captive bred, while the snakes can carry lots of parasites or diseases. It's asking for problems with the snakes and will make that quite some snakes will die.
-I've nothing against taking a few snakes from the wild. But so many snakes that it appears that you plunder a den... I just can't imagine that it's healthy for the wild population, certainly if a lot of females where still pregnant when he sold them. Which makes me wonder if it's not illegal? If it is, you might ask an authority to investigate it on reasons of suspicion.
