My 2 feral cats are envious of each other and one pees on couches, beds, you name it. This product is the best I have ever had and would have never believed it! I used it a week ago on an upholstered chair and the smell was gone the next day. A week later, checked it again and no smell. This is unbelievable and I will continue to buy it to always have it on hand. I can't say enough.
