The catch

A light spray won't cut it. Soak as deep as the pee went, wait 15 minutes, then blot.

Has a plant-based fragrance.

Skip it if

A full soak and a second round didn't clear the smell.

You want an enzyme cleaner. This one is not enzymatic.

The fix in 20 seconds

  • Fresh cat pee soaked into carpet: Nature's Miracle Urine Destroyer Plus Cat.

You cleaned it, and two days later the corner smells like cat again. Cats go back to a spot they can still smell, so the cleaner has to reach all of it. These three work differently.

Quick verdict: Nature's Miracle for a fresh soak, Skout's Honor when the smell outlasts it, Bac-Out for pee, vomit and laundry from one bottle.
