Grammy-winning violinist Augustin Hadelich wrote a little story about a violinist (himself) who plays music for a cat, which draws all the street cats out to listen. He plays Caprice No. 17 by Nicolò Paganini. The cats are so impressed, they start to dance. They aren't very good at the beginning, but as they lose themselves in the music, they get better. Oh, and stay for the twist ending.
Hadelich, who is a cat person as well as a musician, called his story Fantasia dei Gatti, or Fantasy of the Cats. Tam King did the animation. The music is from Hadelich's album Paganini: 24 Caprices. -via Laughing Squid
