This morning Jack was waiting for me in the bathroom as always, and I pet him on the head and then trailed my hand down his back and tail...and....EWWWW!!! A nice brown skidmark on my hand!! I have no idea how he did it -- but he apparently pooped on his tail. While I finished my business he seemed to notice that he was "unclean" and went around the bathroom floor scratching behind himself as if he was in a litterbox and covering his poo. GROSS!
