Gioacchino Rossini (1792-1868) wrote Duetto Buffo di Due Gatti, also known as Le Duo des Chats — The Cat Duet. This link http://www.virtue.nu/mrcat/Track 07_PCM.wav will lead to your hearing sopranos Victoria De Los Angeles and Elisabeth Schwarzkopf sing the duet. The quality of the audio file is not great, as much had to be compromised before I was able to store it on the inter-net. But it's worth a listen!
