Ballet in one act with choreography by Petit, libretto by Anouilh, music by J. Françaix, and design (including the ballet's fantastic cat masks) by Fini. Premiered 22 May 1948 by Ballets de Paris at the Théâtre Marigny, Paris, with Fonteyn, Petit, and Hamilton. It tells the story of a musician who falls in love with his beautiful cat Agathe, who has assumed semi-human form. Agathe tries to be faithful to her human lover but is lured away by the sound of tomcats and the call of freedom. She leaps off the rooftops and the musician falls to his death as he tries to grab hold of her. She falls after him and they are united in death. It was revived by American Ballet Theatre in 1951.
