The real problem with this method is dabbing the tuna on the keys to get the cat started.
Last year one of our cats puked on the keyboard of the old computer downstairs. Fortunately, it was a cheapo Dell rubber-dome and I just took it out back and tossed it in the garbage bin. (The keyboard, not the cat.) It was weirdly satisfying. I dunno what I'd do if one of 'em threw up on my 1391401.
