Our deck sits along an outdoor closet that contains the hot water heater and boiler. Add it all up and you have a good place for a mouse to hide out. Occasionally we would see a certain mouse running across the snow covered deck. There is no way for it to get into our home, so it was a very charming thing to observe. It would often run and climb into our small gas grill, usually after we had grilled chicken or steak. He never came around after grilled fish though. I guess cow grease is infinitely tastier.
After these past weeks of -17 temps he finally hit the wall. It seems that one climbing expedition into the grill resulted in a stuck tail, which spiraled into a frozen doom.
