Cheddar is the one cat that Butterscotch and Nosencrantz will tolerate. He knows he can go in and out of my office/bedroom pretty much any time he wants, if he sits by the door. I let him in while walking by. When I came into the room later, I found him like this.
He seemed very perplexed as he walked around my bed, with the neck pillow on his shoulders!
Best guess: he tried to burrow under my covers and burrowed into the neck pillow, instead. 😀
