Of course that's to protect what's outside from what's inside not visa-versa.

I have to agree about the humans encroaching on animal habitat though. Here in Az and in CA you see stories about how people are up in arms about the bears or mountain lions attacking someone on a jogging path. by a new housing developement.
Uh...sorry but if you're going to build your pretty 500k house in the middle of a mt lions food range maybe you might want to the animal a break. You moved into HIS kitchen, he didn't move into yours.
Having said that, regarding that snake I'd still have to pee myself if I turned around and saw that on my lawn.
