cats and speakers - looking for clues

When my wife decided we need a cat, I went to Home Depot and bought two diffusers (lenses?  gels?) for those four-foot fluorescent light fixtures.  They are fairly thin plastic, translucent, a milky white color, very flexible.  When I’m not listening, they are fixed across the front of my Vandersteen Treo’s with bungee cords.  When it’s time to listen, they pop off in a couple seconds.  Honestly, I’ve never seen the cat exhibit much interest in them, but I mostly worry about when I’m not at home, which is when his mischievous side surfaces.  My wife probably wishes I had found an aesthetically-pleasing solution, but it’s hard to beat the effectiveness, and all for a few bucks.

don't overreact. Cats won't cause any harm to your speakers.

Not really speaker related, but one of my cats has taken a liking to flossing with USB cables.  

Had cats for years and haven't for a while (and never again). Outdoor cats (that I had) in Hawaii and the mainland are bad for natural small critters around the place, so no no no more. Years ago had Vandersteens with built-in cat trampolines and claw cleaning covers...had Vandy re-do 'em and sold them off. So no clawing of up, urinating on speakers (the cat, not me) or making fur 5% of my diet.

For me with Sonus Faber's having two large quality cat scratchers in the room has luckily kept the current Maine Coon interested enough to leave the speakers alone.  We also trim her nails and hang together listening to music. She likes acoustic Jazz and chamber music, but not the blues or rock. 

The first Maine Coon almost lived outside full time and couldn't care less about my speakers. Whether or not your equipment will be safe depends on the cat and whether it has its own space and stuff to interact with that it likes better than your speakers, chairs and couch.
