Why it matters

Nature's Miracle's Oxy formula adds oxygen power for stains and smells that have set in over time. This cat version comes in a full gallon, enough to saturate a carpet spot down to the pad.

Use it for deep, old or stubborn accidents.

Who it's for, and who should skip it

Good fit if

  • Old, set-in stains
  • Repeated spots
  • Large areas

Look elsewhere if

  • Spots already treated with ammonia cleaners (rinse first)
  • Delicate fabrics without a spot test
  • Ongoing accidents with a medical cause

Pros and cons

Pros

  • Oxy boost
  • Gallon size
  • Cat formula

Cons

  • Large jug
  • Can lighten some fabrics
  • Spot test needed

Limitations to weigh

  • Test cleaners on a hidden patch of carpet or fabric first.
  • Enzyme cleaners need time: soak the spot fully and let it dry on its own; don't use ammonia cleaners, which smell like urine to cats.
  • Oxygen cleaners can lighten some dyes; always spot test.
