Cats are strange.

Go find yourself a 100,000 square foot warehouse, empty.
Place an ordinary sheet of paper somewhere on the floor.
Lock a cat in the warehouse.
Come back 20 minutes later, and the cat will be sitting on the paper.

I don't get this behavior. I thought it might have something to do with a cat's need to be as high as possible, but a cat will often forgo a higher perch in favor of a magazine or some paper or your jacket or some cellophane from a dvd you just bought.
I don't get it. I just thought I'd put it out there.
