Ophuria,
Thats my biggest gripe, with this hobby...large constrictors, mainly. Any schmo can go to a local reptile show and purchase these snakes for less than $100. From the get go, they're not properly taken care of and after a little while, the person no longer wants it.
IMO, it's the breeders responsibility to ensure proper housing, to the snakes you're selling. If you're not concerned with who these snakes are going to, then you should not be allowed to breed and sell these snakes.
At one time, when I had 12+ snakes, more than half of them were rescues. I finally got tired of being the guy that everyone thought would take anything and got tired of coming home, after work, to find snakes dropped off on my front steps. Before I moved, I found proper homes for the majority of the rescues. Now, Heather and I finally have had the opprotunity to buy our rare Pythons, that we've been wanting.
I STRONGLY agree with permits, where these snakes will thrive, if let into the wild. I think that Florida should charge 100x what they're charging, for those permits. Then, it would limit (to an extent), the morons that are buying these snakes, because they think it makes them cool.
