Was this godawful expensive? Yes. But was it worth it? Absolutely. A cat got trapped in my daughter's room while she was at her dad's. Poop and pee EVERYWHERE. We used the whole gallon on her floor and the smell is completely gone. The stains are gone. It was so bad that I was going to rip up the carpet altogether and seriously considered just burning it all down. But now? It's saved! I do suggest wearing gloves though. It's itchy when it touches skin.
