My handsome boy (a fifteen pound brown and white mackerel tabby domestic longhair) gets a little goofy every evening at around ten o'clock, whether there's a full moon or not. He launches himself at stationary objects, such as chair backs and the top of his scratching post, causing them to wobble dangerously. Another of his favourite late night activities is chasing a plastic kitty spring wildly around the house, until he loses it underneath a piece of furniture and is forced to take a breather on the dining room table.
