How do I keep my cats off my amplifier?

Here's an idea: dig a moat around both of your amps and fill them with water. Next, stock them with pirhanas, lion fish and great white sharks. If the water isn't enough of a deterrant, the contents should prove effective in eliminating the problem.

If that is not an acceptable solution, you might try a flame thrower, razor wire, a small mine field or you could just gently nudge them away with an Abrams tank.

Ignore the amp and so will the cat!

My cat used to sit on my Proceed AVP for months upon months. I kept gently ushering her off, but she'd always return due to the warmth. Fast forward one year and I had to send it in for service. They called me and said: "What the #@*! did you do to this processor"?
It had one inch of cat hair piled up and in the circuit board. The hair went through the drilled vents in the top.
I also have a German Shepherd who still gets the cat scurrying to higher ground, so that is not a solution. That air bazooka is clearly the way to go. And to all the people with bats and rusty nails, would that be a suggestion for raising children? One should never harm animals, even if you don't like them.

Forgot to mention; serial killers start with torturing cats at a young age. I suppose you can call it a Gateway torture form. Many people have the urge to inflict the pain on the cat, serial killers give in to the urge and act on the impulse. Quite disturbing to see so many suggestions of poison, guns, bags with rocks, bats with rusty nails, etc... Live and let live guys.

Aw, c'mon Adidadi, I seriously doubt any of those suggestions were meant as anything more than for the sake of humor. Can't recall the author of the comic books published a few years back (was it B. Kliban?) titled "The I Hate Cats Book" or something like that. It was a hilarious depiction of some of the scenarios described here. I love animals myself. Not a cat fan myself. Would never raise a hand to an animal though, feline, canine or otherwise. Have donated money to non-kill animal shelters, and have owned some sort of pet most of my life..yep, even three cats among them. I am also posessed of some semblence of a sense of humor. For my own comments, I am sorry if they've offended you. I realize that you must not share the same sense of humor, but obviously some folks do. I seriously doubt we have any serial killers among us. They're all over there in a special ward on AudioAsylum discussing their latest victims ;-)!
