In Cats Knocking Things Off Ledges, players take turns building a wobbly tower of platforms, placing their cats, and batting toys off the edge to score points based on how far they fall. But watch out - if the tower tumbles, you score zero! Earn extra points by landing on specific platforms, and race to be the first to reach the highest score.
