How do you remove cat urine smell from dirt?

There are lots of pet sprays in pet pharmacies and pet stores that should get rid of the stain. Some are generic and get rid of both dog AND cat. If your cat has pooped or coughed up a hairball, pick it up, throw it out and then spray. It should get rid of the stink and hopefully the stain. If your cat (or dog) has pooped, peed, or barfed up on any object that you use AT ALL. Disinfect it AS SOON AS POSSIBLE.
