I have a mouse who has invaded my kitchen. Living in a very old house, this is a frequent annoyance when cold weather moves in, so does the mouse.
Unfortunately, Igor, my cat had lost an eye so he is not such a great hunter.
I had a bag of carmel soy crisps and discovered that someone had ripped a big hole in the bottom. I was not me. It was not Igor.
That leaves only one suspect.....!
