I got a box ( A BOX!) in the mail yesterday with a book that I had ordered in it. It had lots of nice squashed up paper in it so I put it on the floor because I know how much my kitties like boxes (BOXES!).
Later here comes Buddy who curls up in the BOX!, sits there for a while, and then takes his afternoon nap in the BOX! Which is just barely big enough for him. He's back in there today.
