All corn snakes are non-venomous, and while they are constrictors (Squeeze prey to death) They are far too small to do any damage to humans. Dusty is around... 3 or 4 feet now? As long as he doesn't wrap around my neck, he can't hurt me at all.
People need to know that snakes might look spooky, but they're a living creature just like any puppy or kitten or whatever. They don't want to be feared, they want to be loved. I'm happy you have a snake to show snakes are like a cute and cuddly creature. Unless it's poisonous, then you can run around and scream.
