After a long wait (routing problem), I finally received this product that really satisfies me. The smell of cat pee is really removed and the product of the perfume itself is nice (compared to Tracenet which has a stronger scent). This product is a little expensive, but if that's what it takes to not have a couch that smells bad, I take :) After, it is not a repellent, so my cat tends to start .. .!
