Haha, I love that one! Someday I'm going to put a bunch of boxes in the middle of the living room and see if I can get a cat in each one and take a BETTER picture!
I also like the Ikea crazy cat lady organizer. . .aww, I cant figure out how to post a cheezburger picture but I'm sure you can find it if you search for those words .
For 40 years I've been trying to figure out what the attraction is, cat to box. What can they possibly be thinking as they eagerly jump into a box? Is it hygiene, they like the feel of cardboard on their fanny, a personal space? What in the world is it?
