Cats smell bad in general
I picked up a couch from a friend of mine because the price was right (free!) and the thing smells like cat.
Thus far I have burned incense on it, sprayed lots of Oust on it, used a professional carpet odor and stain remover, and cleaned it with vinegar and baking soda. So far the vinegar/baking soda seems to be doing the trick, now it just smells like vinegar
