My cats thoroughly enjoy any classical selections, it definitely calms them down and they all lay around the room listening to it. Many years ago I had a large classical Asian music collection, and the cats I had then also enjoyed it very much, even more so than western classical music. I beleive that the Asian music had more sounds that they could identify with, such as the East Indian esraj (sounds like the human voice) and sarangi (sounds like a cello played in a marble hall) (both are bowed instruments) , or the South Indian veena.
