I think the rear fang venomous may keep some folks from getting into them, either from personal preference or legality.

They are such adorable snakes, I don't know how everyone doesn't want one. Myself, I was told they all under venomous by some of the governmental folks, so until I get venomous permit, no hoggies for me. Others have said they are not considered venomous, but I don't want to risk all my animals on a maybe.
