Was quite skeptical with the number of products I've used in the past to clean up cat urine.  We have 2 cats and a dog - 3 yo cat has recently decided to relieve himself on our carpet. Poured almost half the bottle over the markings, placed a towel on it with some weights and let is sit for 2 nights.  This morning I brought out the black light to test the area and lone behold, 95% of the stain is gone, and the smell!  Also took out the small stain in our kitchen floor rug that he enjoys using.  Used it on the grout next to the litter box and it seems to clear up the marks.  Highly impressed and will be buying again soon to keep on hand.  *I am not paid nor did I receive free product to write this review.  Now to get the cat to use his box...
