“Dueto Buffo de Due Gatti” is a composition attributed to Gioacchino Rossini but is instead a compilation written in 1825 that draws principally on his 1816 opera Otello. Hubert Hunt claims that the compiler was Robert Lucas de Pearsall. The music was a perfect choice for the film, because it brings all the drama and seriousness of the orchestra and movie scenes, with a hint of comical sarcasm of a couple of singers mimicking cats.
