Sharp claws are important. So is style. Whether it is day or night, William finds time to stand by the front door, vigilantly picking at the curtain, adding just the right touch of 'destroyed' to the room's interior design. The best time to scratch is when Anna and Ellen are relaxing on the couch, that way he gets a fresh new pair of knives, adds some style to the living room, and gets loads of attention as they watch him destroy another piece of their house. Where a beautiful piece of fabric used to live, resides a torn-up rag, just what was missing from the living room.
