Out in the garage, I place plenty of old fashioned mouse traps and multiple trays of "used" kitty litter from multiple cats going #1. Mice don't like venturing anywhere that smells like cat territory. (I think it's a union thing).
The cats got the first mouse of the season last week. I came stumbling down the stairs at 6:00 am and barely missed this clump at the bottom of the stairs on the wood floor. It was a mouse head. Just a mouse head. It was like a miniature scene out of the Godfather. I then investigate further and find mouse parts scattered around the kitchen and dining room floor. Not a pretty sight. Of course the wife feigned sleep during the cleanup process. When she heard I was done she then called out for her cup of coffee...
Here's king mouser. (If I could only get him to venture out into the garage, the problem would be solved)
