A little aversion therapy. Set the cat up like Alex in A Clockwork Orange (strapped in, eyes held open etc) Inject a little anti-catnip about 30 minutes beforehand. Then just set up a photograph of him scratching the speaker right in front of him. Play beethoven. After a few sessions of cat therapy he'll be unable to scratch the grills without heaving chunks. If that doesn't work move to something more drastic - like cat with asparagus in a light cream sauce.
