I apologize for the poor quality of this video. I am actually pretty humiliated that the Human is posting it at all. But my fellow Royal Punapippuri insisted, and I am nothing if not his obedient servant. This is quite a gentle butt-thumpin' as butt-thumpins go. Sometimes I like a little firmer touch, but it will do as an illustration of the practice at Chez Spitty.
