& don't play harsh music, play oldies type music. I put on Abba, & it did the trick. If u put on harsh music it'll vibrate him too much & he may become ill, stop eating, or even die. & don't play it too loud, same reasons as the vibrations. hmmm pretend ur trying to put a baby to sleep with soft quiet music & poof there ya go
& if u use CDs change them on a daily bases, u don't want him to get too use to the same noises, u want him to get use to many different noises. Make sure there is no music at night, he'll need his beauty sleep
