There was an earlier thread where someone complained that his male cat is spraying the computer. Mine does that too. He used to do it occasionally, now he's doing it every few days. He is spraying it because he sees other cats outside, and he has to mark it so the other cats will know its his.

It's a mystery why the cat feels he has to protect the computer. It already has Norton Antivirus, SpyBot and AdAware.

(It's also a mystery why my neighbor wants her cats exposed to fleas, tapeworms, dogs, cars, and feline leukemia.)

Of course, I wish my cat wouldn't spray the compter, but this cat has many desirable qualities which offset the presence of a little sterile saltwater which is all that urine is. (Granted, some of the salts are smelly.) For example, he is wonderful at soothing upset people. He's a veritable feline therapist.

So I bought a pad of newsprint. I take a sheet, fold up the bottom two inches to make a pocket, and I tape up the fold. Then I tape the entire sheet over the computer. When it assumes a yellow, mottled appearance, I change it.

Where to put it? Put it with his litter box, so as not to start a new site which needs spraying.

It's not a perfect situation, but it works for me.
