I heard that if you ever get entangled with a constricting snake that gets the better of you, that if you can manage to jump in the shower and hose it with warm water, it will let go. I think I've seen some documentaries where people have a hose connected in their snake room for cleaning, and dislodging.
AW have you heard of this?
I agree, snakes have personalities, and vary one from the other. I can definitely tell when I need to be a tad cautious around my own snakes. This usually means that I haven't fed them before they actually get really hungry. I have two spoiled snakes who will only eat gerbils (which at times are hard to come by).
