There's a stray cat that lives around my house and used to come up on the back deck whenever I went out to smoke a joint. One day I blew some smoke into it's face just to see what it would do. Apparently the cat didn't like it cause it jumped down and ran away. Now whenever I come out to smoke and as soon as I just up the doobie and the cat smells the smoke it runs off. I never forced the smoke on the cat, it just happened to be sitting there at the time.
