Morticia, who is very fluffy, has a Tail of Mass Destruction :D She can't help it, she has to wave her tail over the table as she goes past and pushes everything off onto the floor. Apart from that, and her mad half hours, she's not bad though - can walk along the mantelpiece without knocking anything off unless it's deliberate. But her tail causes as many problems as the other 3 cats put together.
