Exactly me point. Cats are the only animal in the world that kill just for the fun of it. Or "practise" as you call it. And exactly, "a little bit of imagination". If you teach your kids not to mess with snakes, they won't. If you teach them. You must teach them to respect them, not go around killing every one they see like maniac mass murderers, but to just leave them alone. Leave a snake alone, it will leave you alone. The only exception to this may be cobras, when they are guarding a nest. And pythons that are actually big enough to eat you. Many a time I have almost stepped on a snake, actually touching it with me shoe, and then watched it crawl off. It didn't even try to bite me, it just wanted to leave. Same goes with most spiders, and most other animals.
