I had an elderly cat who was unable to catch mice anymore, so I took her place. I caught one mouse trying to climb into the house by a window. He was cute. Not your normal grey thing, but he was brown with "Mickey Mouse" ears. I caught him by the tail and put him in a canning jar and drove 5 miles away to the woods and let him go. Just didn't have the heart to hurt him.
My son used to have a boa constrictor. You know what they eat...well, he was moving and brought the aquarium with snake to my house to babysit while he moved and "settled in." I was at work. Can you imagine my surprise when I came home? This thing was to be here only a day or two but it turned into 2 months and I was very unhappy. I had to feed the snake and refused because they were living mice. So the next day my son took the snake out of here. Thank heavens!
