I had to excavate a family of four mice that had burrowed themselves under my kids' playground this morning. My dog, who although she is definitely on her last legs is still a killer, found them killed one of them, I'm guessing, playing with it. I had to dig the other three out with a mini shovel and put them in a box, still alive while one of them was crying. It was fun. I had to get rid of them somehow. I don't want them in the house. They were fairly big for mice.
