Hahaha! My kitty plays a crazier version of this game! She loooves to hide out under the furniture, and jump out to attack as we walk by! Sometimes there are no claws...."false attacks"....she jumps up and away, to wait for her next victim. But the other times....she bites ankles or latches on with her claws. Mind you, these are unprovoked attacks. For her amusement only.
