Eliminating cat urine odor can be tricky. Cat urine typically produces an especially persistent, unpleasant odor and there are a few products you can utilize to eliminate them. Enzyme based cleaners and odor removers are fast-acting and begin working as soon as the product touches the affected surface. Removing the entire stain is important because if there is any odor left, it will encourage the cat to eliminate in that area again. Finding a good product to remove the odor is a good solution for both you and the cat.
