With some doubt and hesitation... I ordered the bundle to tackle a section of carpet our elderly cat had used repeatedly. We had tried all kinds of things just short of cutting out the section... and my husband was especially skeptical that anything would resolve the odor! We have applied this product every day for nearly two weeks as directed and even my extremely sensitive nose no longer smells “cat” when I sit in the family room. Unfortunately our cat crossed the rainbow bridge... but I do think we have successfully resolved the situation thanks to this product!
