I wonder what they use in common household wire here in Canada? I have a mouse or 2 living between the wooden floor and concrete floor of my basement. They were in the walls a bit too, but lately it seems just under the floor, near the furnace.
Believe or not since I started this thread, I had corned a mouse under my stove, then in front of a washing machine, and I had a Sony 5-disc CD player standing upright by the wall next to the washer. It's broken and the case was not screwed on, and the mouse tried to escape running between the case and internal parts. And I closed the case together and trapped the mouse inside.
Then I put the whole thing in a garbage bag, and I shook it a few times trying to get the mouse to the bottom of the case, which was barely fitting together. And IDK if the mouse got a bit crushed or hit it's head, or had a heart attack, but it was dead when I opened the case. No blood tho. Or it sure seemed dead, and I flushed it down the toilet, poor little guy.
