Give your doc a call and ask, or call your state's rabies hotline. I think it does give you protection, but I'm not positive. Perfectly normal behavior for it to go after you since it was under general attack. You said it. Even if you remember to check and empty the "humane" traps, the critters have peed all over themselves by the time you get to them, and letting a shivering soaked mouse out in a field in the middle of winter is doing it no favor. My attitude is same as yours. I hate killing things and leave them alone unless they're really causing problems. But mice in the house are beyond the pale, so I use snap traps. Farmers around here generally use those glue traps, and though I can understand why (with dogs and barn cats, etc., poking their noses everywhere, poison and snap traps are out), it's still a horrifying way for any living creature to die.
