Yes - Bo has! I used to live in the country with a couple acres, and Bo was allowed outside. I remember his first mouse - he was playing with it, and in his excitement, it got away.


Then there was another time (same house) I knew there was a mouse in the kitchen cabinets. In my junk drawer I found chewed up napkins and photos, and a few mouse droppings. All four cats would sit and stare at the cabinets, but they couldn't get at the mice. Finally, I used my head and opened all the cabinet doors and drawers before I went to bed one night. The next morning, there was a dead mouse on the floor.

We plugged up the opening (the vent from our stove that was built in to the island thing) and no more mice in there.
