I've only dealt with the ones I've caught as a kid. Those always had nasty attitudes. But I'm sure captive bred will be a little better. If you're worried about getting bit, get a few (or make) appropriate sized snake hooks to handle/ hook train the lil bugger and use tongs/forceps to feed it.... that way your hands are never in the way to get bit. And once you get confident, you can start picking it up by approaching it from its back end, not the head. Getting bit by a rat is about as bad as getting nailed by a ball: a sharp surprised pain followed by a bit of blood, nothing serious.... but still not fun in my opinion. I don't like to get bit by anything and will even hook a ball if its being feisty lol
