Additionally, while the enzyme-based formula is effective in eliminating organic odors, it might not work as well on inorganic sources.

Its key strength lies in the enzymatic formula that keeps working as long as any urine residue remains, which makes it effective for thorough odor removal rather than just masking smells.

The 32-ounce spray bottle provides a moderate coverage area suitable for cleaning multiple spots but might require multiple treatments for larger or more heavily soiled areas.

It offers a safe, enzymatic approach that cleans and deodorizes without harsh chemicals, making it a trustworthy option if your main concern is cat urine odor and stains.
