Saved me from having to take pills to lower my blood pressure every time I walk into a room! With 13 cats, most of whom are very bad (probably because of so many cats confined in an area), but still...I am VERY sensitive to the urine smells. This stuff has saved my marriage and my sanity! I am not a housekeeper so spraying and walking away is my kind of cleaning! They spray our curtains and walls, so I'm constantly spraying, but this stuff really really works. I don't care how expensive it is, I will continue to buy it and hope the company doesn't go out of business or something, because nothing else has saved my health and my stress levels like this stuff. We still cannot keep up with all the cleaning, but this stuff helps so much!
