It's so hard to eliminate the residual smell from cat urination, and then they continue to use the same spot. Do you have "Natures Miracle" or some other enzyme cleaner? That's really the only thing that will effectively eliminate the residual smell. Don't use any other soaps or cleaners first, always the enzyme cleaner. You can soak the purse in it. Personally I would toss the purse unless it's washable/soakable.
