Well, we were a no kill family. We had a little humane trap that caught the mouse in a little plastic box. I'd always heard that if you let them free just outside the house, they will find their way back in, so you have to release them at least 2 miles from your home, so dh got the fun job of driving the trapped mice a few miles away and releasing them into the wild. Unfortunately, one particularly active creature tossed its weight around inside the trap so much that the trap fell out of dh's hand, broke, and let the mousey free. Fortunately, this happened outside our house. But, at that point, dh put his foot down and said that we would henceforth use the traditional neck-breaking style of trap. So sad.
