My one cat Peaches loves Pavarotti. Actually, both cats like anything classical.
My cat Czarina seems to have a penchant for Opeth. She also seems to like Schubert. Good choices, both.
My cat Norman likes music not so much as a listener but as a participant. Every time I sit down to play the piano, he jumps up on the bench beside me and plays "harmony." He's especially fond of the lower pitched keys.
