How to Neutralize Cat Urine on Concrete

Cats provide many benefits including love, entertainment and friendship. However, not all aspects of owning a cat are positive. Cat urine leaves a pungent and unpleasant odor that can last long after you have cleaned it up. Concrete has thousands of tiny pores, which will absorb the urine and trap the odor in. To remove this odor, you must neutralize the cat urine. Remove the cat urine as soon as possible to prevent staining.
