Usually, when my cat, Collette, is within earshot of the music I'm playing, she's in the same room with me. Yesterday, when I had to leave the room, I made a snap decision. Ordinarily, I would have turned the stereo off. Brahms composed such a moving second symphony, though, and my hometown St. Louis Symphony Orchestra was playing it.
I let it play out so Collette could hear it. She hasn't picked up a violin yet and started playing it. Still, considering that she was still curled up on the sofa when the symphony ended, I bet she enjoyed it.
Maybe I'm projecting, but what's wrong with letting one's pets enjoy some of your favorite sounds?
