The name is connected to an episode which occurred during the 1509 siege by the German King Maximilian I during the War of the League of Cambrai. According to legend, a cat was flayed alive to frighten the enemy with its screams. A sculpture of a cat jutting out of a niche was placed on the outer part of the tower facing Codalunga Street in order to commemorate this event, as well as symbolize the freedom of the people of Padua.
