I LOVE this product. I could not lay down here next to our radiator cover before my pet peed. Our cat Sophia developed kidney stones. We didn’t know until she started peeing here instead of her litter boxes. After her kidney and bladder surgery she still went back to this spot and one other to pee. The smell was driving me insane. I tried EVERYTHING. Literally. Baking soda, vinegar, homemade enzyme mixtures, name brand ones. You name it and I tried it. NOTHING worked til this product. I’ve had to treat the area several times because every so often she will go back but the smell is GONE! I’m laying on the floor typing this and there is no pee smell. I wish I could give it 10 stars it’s about time to restock. The gallon lasted us a year and that’s even using it on the porch outside. We have a feral cat issue in the neighborhood and the male cats sometimes spray our house. This even gets out Tom cat smell on brick and wood!
