What's the deal with scaleless snakes?

That may be your opinion, but I strongly disagree to do selective breeding for deformities and other negative traits regardless if there is market for it. Not just specific to reptiles, but any animal. It can't possibly lead to anything good, and you're not making 'Happy animals' by selectively breeding them for these traits. They deserve a lot better than that.

Also, heatpits do not make up for true vision. That's similar as saying that hearing makes up for true vision in humans. They can detect something that is hotter or colder than the things around it, that's it basically.
