I also recommend enzymatic sprays that completely destroy, not just mask, any odors in the spot. This helps prevent Fluffy from returning to the same spot because the odor is completely removed. The same tips apply to fur balls, vomit, or other spills and accidents. The sooner an accident spot is cleaned, the better the results. Spots that are left overnight or longer will be more difficult to clean. Always remember that bleach, ammonia, or other harsh detergents are too harmful to your carpets or floors.
