Did you let your cat listen music?  

why not,because i want to lesten music,so i let my car lesten it too.but actually, my cat has no response to any music,it is only interesting in food,and the little ball it play. i don't know whether the music can help it grow,but i can be delight from lestening music.

Sometimes if I decide to play the radio the cats listen to whatever I'm listening to. Sometimes they like it, other times they sleep right through it. However, the radio is never on when I or George aren't home. I don't turn it on for the cats' benifit eaither. They listen to music when I listen to music, end of story.

Well, I don't know if it helps them grow, but I know my oldest cat loves listening to music. She has a preference for the slower-symphony music, we've noticed
