On a cold dark night, a mama cat seeks shelter for her newborn kittens in a Parisian theater known for its ballet and for the famous artist who comes there to sketch. While the ballerinas practice, Bijou, Bonbon and Beau make themselves right at home to the delight of the dancers as well as the artist who quietly sketches them. Oh, the mischief they get into! They chase the ballerinas, sleep in their toeshoes, and frolick amongst their tutus. Until finally, the irritable stage manager threatens to throw the mischevious little trio back onto the street. But, on opening night, it is Bijou, Bonbon and Beau who steal the show.
