If you start out with something small and slow, like a garter snake, you might be able to handle them. They eat fish, so you wouldn't even have to watch them kill a bunny or something cute. You'd just go buy some fifteen cent feeder fish and let the garter snake eat them as needed. Turtles are really nice too. They are slow, and depending on the type, pretty hardy. I actully love turtles and spend my springs and autumns moving turtles across busy streets. I just can't stand to see them squished.
I think you would do well with my last dream pet. Bath time would be fun.
I always wanted to own something like a snake, lizard, or turtle, but they kinda freak me out so I don't think I'm getting one anytime soon.
