I cannot speak more highly of this product! I have used it religiously since the the first day I received it! I'm training my three Frenchies, and this product is literally a miracle. My male Frenchie decided to mark the cat tree. So, to test the product, I didn't wipe it up. I just sprayed it and walked away. A few hours later, the pee was completely gone! No smell! No stain! I couldn't believe it! Oh! pro tip! spray it around the base of your toilets. Especially if you have boys!
