Good for you Bwallace. The only snakes that I kill are the water moccasins that I cannot catch and move off our property. They are too fast and to dangerous to catch.
My wife's cat used to bring snakes into the house all the time. It never brought in a poisonous snake. Luckily for them, my wife also doesn't have any problems removing them as long as she can recognize which type it is.
