Do not hesitate to purchase this product, it really does everything it claims! We have a cat that stopped using her litter and leaving small urine spots all over the house. Xrays showed she had a large stone and a severe UTI. We got her on meds and thought we were done but she kept going back to those spots. Purchased this product, treated the spots and no more stains, smell or repeat urination. I've also used it to remove blood stains; spray it on and let it dry-stains gone. This is a must have item for the house.
