LOL, Charles. They're certainly strange creatures.
Elvis has recently discovered that the highest place for him to perch in my room is on top of the cable box on top of the TV. (It's also warm up there.) The other night, he was up there staring intently at a point on the wall. I even turned the light on and checked it out because I thought that there might be a bug or something. ( ) Of course, there was nothing there, but he just kept on staring. Now, every time he goes up there, he stares at that same spot. I can't figure out for the life of me what could be so mesmerizing.
