I have used his product for many years, but a few years back I switched to the unscented version. I retried the original again and it seems to work so much better! One of my cats peed on my glasses case (cloth). I sprayed it and when it dried the stain and odor were gone.
Waste of money. Does not help even on a non set in stain.
This did not work the first 2 times but now my cat has not poop outside of litter box. I am happy so far have not had the product that long.
