Decided to put on clothes and do a walk, letting it go part-way. Spouse joined me. I was really hoping it would be a different mouse than the last time, because if it's the same one, after one more try, dropping it off a car-drive away, I was going to have to consider killing it. Relief -- it was different. A medium grey, much smaller critter. And very, very scared. The trap was vibrating as I carried it.
For the past couple of weeks, we've had a large hole in one of the walls of the house as construction was being done -- but middle of last week that was finished -- so I was considering taking the traps down. Guess that is not to be.
