[Long story, feel free to skip to the end] My house is a tad porous and my backyard is the woods so mice move in from time to time. I get rid of them, it lasts a few months and then I have to do it again. It's one thing to hear them in the walls or attic crawl space but every once in a while they raid the dog food dish. Years ago I found they had been stashing the bits in a stored pair of hiking boots. I went to put the boots on and one was filled to the top with kibbles. (Actually it's Science Diet.) So last night the dogs went vicious, I thought they were attacking each other but when I got to the kitchen where they were trying to get into a space under the counter. They were trying to get at a mouse they smelled, heard and/or saw. I thought I had been noticing the dog food dish emptying when the dogs were sleeping in another room but I wasn't sure. And sometimes they bark at things which are not alive. It was late so I put the crockpot lid over the dog food dish. This morning the previously filled bowl was almost empty! There's no way even dozens of mice devoured that much food, and if there were that many mice I'd have noticed sooner. Somewhere hidden in my house there is a huge stash of kibbles. I should set up a camera and make a YouTube video. There's probably a single mouse stealing one kibble after another all night long.
