A Skateboard Cat-astrophe is an entry in the Hardy Boys Clue Book series, aimed at younger readers. Frank and Joe Hardy are on the case when chaos erupts at a local skateboard competition or park. A series of strange accidents and damaged equipment, perhaps related to a mischievous cat, suggests that someone is sabotaging the skaters to prevent a specific person from winning or to shut down the park. The boys must observe the ramps and rails, question the competitive skaters, and figure out who is behind the "cat-astrophe" before someone gets seriously hurt and the skate park is closed for good.
