Instructions
Locate the areas where the cats are doing their business. If you are having trouble locating the source, use an ultraviolet light at night. Dull yellow stains are signs of pet urine. Place a marker, so you know where to clean during the day.
Use the trowel to scoop out a small amount of the dry lime. Sprinkle it around the area. Be sure not to overdo it, as too much lime can throw off the pH balance in the other direction. If you are unsure of how much to apply, you may one to consult a lawn specialist. Every lawn's pH is difference, and a specialist can conduct a thorough soil analysis to advise you of a proper amount.
Water the area. The lime will hydrate. This will cause it to react with the urine, neutralizing its acidity, while also absorbing the smell.
