We went a step further and just put a door to our basement. No animals down there period. Now the cat is gone so it matters alot less, although when she was alive, she never touched the speakers.
Then there's a friend of mine, a vet, who has 2 cats and needs to put shock pads and sticky side up duct tape to keep them off his equipment.
