Well.. most people don't realise that snakes not shedding in one piece is not normal. So I would not say that's abuse, but ignorance.

An absence of water for the snake is getting there though. You have to realise that a lot of the animals these guys get are imports. They are stressed and most are unhealthy when they get them. They may look less than healthy in even ideal conditions for a time.

I don't doubt they don't take proper care of them though. It's a rare pet store that does unfortunately.
