We had mice relocating the dog food to the top of the pick-ups engine. I've found staches in the attic, Eric's old boots, plastic cups, anything that would hold dog food or Super Scratch. It's mainly outside now and I have a mouse that cleans up anything I drop on the floor of the feed room. That reminds me, I've got to unload 250 lbs. of feed tomorrow morning, hope it's not frosty.
