Right...I was just reading in one of the reptile magazines that John sent me about how if you are afraid when you are holding a snake, you tense up and stuff and the snake can sense you being uncomfortable and tense, which makes the snake go on the defensive and the snake will often then musk and poop. I also think that snakes probably smell things on us like other animals and things like that and become defensive. Perhaps they may even smell something that smells bad to them and become defensive.
