cats and speakers - looking for clues

What you need to do is take a portable bluetooth speaker to the pet store, play some jazz and get the cats that stop and listen. 

I’d be more careful of cables. I had a cat many years ago and then got my first true high end home system. I had Transparent Plus IC’s and speaker cables. Not cheap. One day I noticed teeth marks everywhere. I didn’t even know cats did that. Well that was a long time ago and I will never have another pet.

I wouldn't worry about it.  Most cats will be indifferent.  Over many years I only had one cat who thought the grill cloth made a convenient scratching post.  My best cat story though is about the late and sorely missed Ben.  He liked music and would sit at my feet and listen actively, head moving back and forth from left to right speaker as musical elements caught his attention.  He preferred Classical music, particularly Beethoven symphonies, #7 especially.  Who he could not abide was Rod Stewart.  Literally reacted to his voice as though in pain and would bolt from the room.  As Rod was a favorite on a local FM station, this could happen without warning.  Ben would look at me as though I had betrayed him after each and every encounter.  I miss Ben.

I've owned several different species of pet all my life. Dogs,cats,birds, reptiles and some exotics,(Coati, Leopard, Armadillo, Honey Glider, etc) the only pets to have ever caused damage to and speaker/equipment, were my big birds, Macaws and Cockatoos. 

I had cats and fancy stereos for the past 40 years and was always able to control them by saying no as they approached within 2 feet of equipment and speakers . Teaching them no came in handy for many reason besides stereo. With a few cats, the word no had to be reinforced a few times with a gentle spritz from a squirt gun but they tend to learn fast
