Nutmeg is pacing in circles, pawing the door that leads to the deck, maniacally licking his bottom and dipping his paws in his water bowl before sniffing and then drinking from them. Does he think there's arsenic in there? Why the compulsive butt-washing? Why the caterwauling? Does he feel he left some unfinished business outside earlier?
