Do Squirrels Like Red Lights?
We had some lights outside our house for Christmas, with one end on a spruce. When we went to take the lights down earlier today, my wife noticed that one of the cords had been cut. Then she found one of the light bulbs was under the spruce - both ends had been cut from the rest of the line of lights.
The cord clearly had been chewed through, as opposed to being cut by a knife or scissors, so our only conclusion was that one of the squirrels who frequent our yard had decided they needed a red light for Christmas!
