Last year, I never got around to setting up my tiny little Christmas tree, because up until shortly before Christmas, Frosti was still in the house and I was sure I would look up to see him dragging it across the room.
This year, I pulled that little tree out of its plastic storage bag and brought it up to the living room. I have a large wooden chest in front of the living room window, covered with a sheepskin, so I put it there and plugged it in.
At first, Aska paid it absolutely no attention whatsoever. For about an hour, she stayed on the top of the cat tree, not 5 feet away, playing, napping, and grooming herself.
