Beau or Felicia have never caught a mouse. I don't think that I have to worry about them. I live on the second floor, and the only way up is by stairs.

I did have a cat that caught 2 mice, (I was in a first floor apartment). Each time the dead mouse was just inside the door. (Like the cat wanted to make sure I saw it.)

I had 2 cats and the mice were already dead, so I don't know any details.
