My grandmother had a cat that seemed to like music to some degree. I can't really remember what kind of music he liked specifically though. He was rather picky I guess. I used to play piano sometimes when I visited and he would sit down and listen. I got the idea that he must have liked it because when I stopped he would get up and leave right away. I thought it was really cute that he liked to listen to me. No one else in the family, including my grandma, believed he was actually listening to the music though, they all just thought that cats were not capable of enjoying human music at all and he just happened to want to sit down there, and then got bored and moved on.
