Is he breathing or sleeping?

I just had to share this picture. Isn't he cute?? That is about all he does all day long. I sit at my computer either reading or writing (not so much lately) and he will sit behind me. I can't see how he can be comfortable since his back legs hang off the edge.

Every now and than he will move and I hear the china bumping. I guess that is his way of letting me know he is still alive.
