Cat-proofing your speakers...

What is yellow-brown and looks good on a lawyer?

A Doberman.

Sorry, I couldn't resist.

The only way to cat-proof (as well as child-proof) your house is not to let them in. Cats cannot be stopped. They have to investigate everything for the reason of their safe being. The only way is to place items so high that cat cannot reach (jump) - not likely. I have tried to spray nasty smelling stuff designed to keep cats from the furniture but it did not stop my cat from scratching. Young cats are the worst.

I really loves cats so much!..... well, compared to Lawyers, that is

I have two books "100 Uses for a Dead Cat" and the sequel "100 More Uses for a Dead Cat" Once you do the deed I would be happy to make some suggestions. The most creative is have a taxidermist install a pencil sharpener just beneath the tail:)
But in reality and seriousness, I don't think a cat can learn to not do what it has grown used to doing. De-Claw it or make it an outdoor cat. A leash? A cage? A good dose of qualudes in its milk each day? Electric pads around the speakers that won't ruin the bass response? Just some ideas that probably won't help. One last one leave the door open and wait for it to run off with that Siamese down the street.

If the cat is de-clawed, it should be no threat at all to your equipment. If you are not willing to de-claw it, then that may be an issue. One of ours is de-clawed, and the other isn't, but neither of them ever scratches at my floorstanders.

Seriously, cats CAN be trained, perseverance and patience needed. Can you close off the room when you are not on guard? My opinion is that de-clawing should never be done.. except for Attorneys, then tongue removal and.....
