It depends on the type. Rattlesnakes live in my area, but so do a lot of harmless snakes. I kept a king snake for a while after my cat nearly killed it. It didn't want to be a pet, so when it was healed I released it. During the time we had it in the cage, we called it IBM, short for "It Bit Me" since it always tried to bite when we fed it. But I've seen some beautiful pet snakes.
