I have a 17 year old Persian who has anxiety. Her way of showing me that she is upset is to urinate outside of her litter box. I have tried everything on the market from generic product, name brands and even home remedies and nothing has worked. This is the first product that I have found that actually gets rid of the odor. Anyone with a cat knows that cat urine odor is the hardest smell to get rid of and if you don’t get rid of it completely they will continue to use the same place (which happens to be my couch). I have been using this for several months and no sign of the odor or repeat performances by my girl. This product is truly amazing and I don’t have to worry about using harsh chemicals around her or my other pets.
