I also have a woolite pet order and stain remover that works really good too -
Also here is a home remedy for pet urine -
Pet Urine on Carpet: First, blot up what you can with paper towels. Then, with warm, soapy water and a clean cloth, blot the area clean; rinse with clean water; blot until dry. Next, combine 1/3 cup white vinegar with 2/3 cup water and dab it on stain; rinse with clean water; blot until dry. Once the area is totally dry (at least 24 hours), sprinkle entire carpet with baking soda or rug deodorizer; vacuum after a few hours.
