When I was staying in Ohio with my Mother (long story) we had a mouse problem. Five cats she had and yet we had a Mouse Problem. We shut all the cats in the kitchen every night for a week, the cats swatted the mice around but just thought they were live-action toys. In the end I just went out and bought mousetraps at a dollar apiece they were. (At least they worked!) I miss these guys, they summed up things so well.
