Ok well Im gonna be honest one here...I have my leo's on either side of my TV in the living room. and I play my pandora, and movies all the time. Its never made them flinch. Infact I play my music on saturday afternoons when Im cleaning and such and they are usually completely flat out asleep..legs all in different directions. Ive just had a hugely successful breeding season with 8 babies and two more to go, my female weighs more now then she did before breeding. Like literally my guys don't seem in the least bit phased. So thats my experience...but Im a true believer in the fact that every animal is different.
