Right after I installed my Viair air horns several years ago (Not to worry, I no longer have them) I had a cat saunter across the street in front of me. You know those kind of cats that keep doing that . Anyway, I gave a blast on the horn and I swear that cat ran the rest of the way across the street on his front feet, with his rear end up in the air, as if I was close enough to run it over. That made my day, after installing the horns!
