I went into the pet store today to get my mouse every week like I always do, same store, I've noticed this before but never said anything about it.

The BP's there have no hides, they just have a water bowl and repti bark. and I don't even think they are heated, I don't know about that cause I didn't see the bottom of the tank though. Isn't this a no-no though?

How do the snakes live like this?
