Snakes have no arms or legs, so they will wrap part of their body around whatever they're on because they're afraid of falling. They're holding on; not trying to strangle you. Plus, they're cold blooded, so they like higher temperatures - like ours.Haha - I was worried about that years ago when a pet store asked me if I wanted to hold a 12 footer. The snake must have really liked me, because he started wrapping around me and giving me a really good hug! It took two big men to free me from this fond embrace!
Sadly, it's exotic pet stores and short-thinking people who cause problems like in Florida. But, I did enjoy taking my kids there - very interesting and much easier (and cheaper) than going to the zoo
