Cat urine can be particularly persistent when it penetrates below the carpet surface. The Carpet and Rug Institute (CRI) notes that complete odor removal is unlikely unless the urine itself can be completely removed and that odors may become noticeable again during periods of high humidity.
Cat urine is concentrated and strong smelling, and cats often return to the same spot.
Humid Maryland summers can reactivate residue and bring odor back.
Urine in the backing is harder to reach than urine in the fibers.
Targeted treatment, enzyme application and extraction address reachable contamination.
If pad and subfloor are saturated, replacing the pad or carpet section may be the only full solution.
