And now, a cute picture of our cat.
This picture illustrates that principle two-fold. The giant cardboard box in the living room is our new coffee table before it was assembled. Here is Violet, sitting not just on the giant box, but on my laptop case on the giant box.
BTW, I've read that the "if there's a thing, the cat has to sit on it" principle has to do with cats' territorial instincts. Any zoologists out there know if that's true?
