I was skeptical but I was also desperate. I had tried EVERYTHING. Natural home remedies, shampooed my carpets over and over, tried the enzyme products, I even called out a company that wanted $700 to shampoo my one room. The awful cat pee smell was just getting worse. Everything I was doing seemed to make it worse. After watching their video about why this product was different, I decided to give it a try. It's peroxide based. I recived it yesterday. After months of cat pee smell, I can finally breathe!!! This product is amazing! The video explaining why it's different is also great. I wish I had found this months ago!!!
