Cat-proofing your speakers...

Kij is once again pretty spot on.

I put it a little differently.

You can hope for 'cat resistant'....probably not more. Cat proof? Nearly impossible once they get there single cell brain on a subject.

IF you make an 'issue' of something with violence or spanking the cat, it'll take that as a challange. You are than done-for.
Try water / amonia in a squirt bottle or perhaps a heavy citrus smell which cats do not like.

My cats NEVER looked twice at my nice, tall, Magnepans.....But they DID like music.

Socialize the cat to the room with you there. lock the door when you leave. keep an eye on 'em at all times as you build confidence.

Sorry, Chad, but even though I'm a cat lover, I must admit that dogs are technically smarter. It is very unusual for a cat to obey any verbal command. I had a pair of exceptions, too. My wife would go out and yell at 'em in SPANISH and they'd come running. Understand Spanish? not a chance. Food? more likely.

Cats are, however, more critical than dogs. If you are judged 'worthy' of respect, you'll be OK. Dogs are pack animals and just follow the boss around.

Don't forget the rules::
Dogs have owners.
Cats have staff.

Yeah, Chad, I've had this chat with other cat-people. They all 'mystify' these poor beasts and impart great powers to what is essentially a dumb animal. In one test, dogs will recognize themselves in a mirror, but cats? Forgetit!
Don't forget, I've owned several cats over the years, but never a dog. by choice.
Cats are mechanically clever. You can teach the essentially neat cat to use a flush toilet.
Innovative....they'll mess with something until they get a result. and remember.
Users. Once you are 'on staff' they'll expect good service

But, I've seen a cat back up to an outlet and let fly. Big 'explosion' with breaker popping and a terrified, running cat. It did it the next day, again, just to be sure?

Some anti-cat humor is simply unfunny. make the same joke about a dog and you'll get raked. You'd be better off with a Scottsman / Sheep joke.

I think that WILD and big cats may be smarter. They are under different pressures than what is pretty much a domestic animal...the 'house cat'. Just like wolves may be smarter than domestic canines, and some sub-dog forms like the Chihuahua.
