RE: For those with Cats, Presenting "Monorail Cat"
I was house sitting one winter. It was being a pretty nasty winter with one storm after another and 20 below temperatures. Since I was only there for a few months, I didn't bother to "install" my digital thermometer, I just put the remote pickup on the windowsill and closed the window on the wire.
One morning the wind was blasting and the furnace was running. I looked at the thermometer and it said 63. What? I pushed the curtain aside, and outside the window, the cat was sitting on the remote temperature sensor.
