I recently saw a fb suggested ad for My Pet Peed in my news feed. I decided to order one container to try it. I was having a problem with a recent male rescue that was marking. I tried Shout, Zout and Resolve with no such luck of getting the entire stain or smell out of my carpet. Only the professional carpet cleaner could remove the stains. I decided to try this product after reading the reviews. I was AMAZED! As soon as I sprayed the spots, I could see the stain disappear. I followed the instructions and left it alone and they were gone. No trace or smell. I would recommend this product to all pet owners!!! Especially if you rescue of foster. Fantastic product.
