In short
Blot cat urine up at once with clean white towels, pressing down with your weight until they come up nearly dry, then rinse lightly with cool water, blot again and treat the spot with a cleaner made for pet urine. Cat urine is concentrated and soaks quickly into the backing and the pad, and urine that has dried there may not come out.
Worth remembering
- Blot and press, never rub. Swap in dry towels until they come up nearly dry.
- Keep ammonia, bleach and heat away from the spot, and never mix ammonia with bleach.
- A cleaner made for pet urine does more than a household spray, and it needs time to work.
- Old urine in the pad may not come out, so tell the cleaner early.
The first minutes
Put on gloves and lift any solids. Lay a clean white towel or a thick pad of paper towels over the spot and press down hard, standing on it if you can, so the towel draws urine up out of the pile. Swap it for a dry one and press again, and keep going until the towel comes up nearly dry.
Never rub or scrub. Rubbing pushes the urine wider and deeper, and it frays the fibers into a fuzzy patch that stays after the stain is gone.
Rinse lightly, then treat
Pour a little cool water over the spot, only enough to dilute what is left, and blot it up again with fresh towels. A wet vacuum, if you own one, pulls the diluted urine out faster than towels can.
Then apply a cleaner made for pet urine, one that says it breaks down the compounds behind the odor instead of covering the smell with perfume. Follow the label, keep the spot damp for as long as it directs, and blot again. Try any product first on a corner nobody sees.
What to keep away from the spot
Heat, ammonia and bleach all make cat urine harder to deal with. Heat from a steam iron, a hot cloth or a hot setting on a machine can fix the stain and the smell in the fiber. Ammonia is already part of what makes old urine smell, and a cat may read an ammonia cleaner as another mark in the same place. Bleach strips color and leaves a pale patch that no cleaning will bring back.
Never mix ammonia and bleach, even in small amounts, because the mixture gives off toxic gas. Use one product at a time and open a window.
Finding spots you did not see
A cat that has marked once often returns to the same area, and old spots are easy to miss. In a dark room, a small ultraviolet flashlight makes dried urine glow. Circle each patch with chalk or tape before you switch the lights on, because the glow is gone as soon as the room is bright.
Other things glow too, including some detergents and spilled drinks, so let the light find candidates and your nose confirm them. Treat every confirmed spot, including the ones that look clean.
When the urine has reached the pad
Cat urine soaks through the carpet within minutes and meets the backing and the pad, which hold liquid long after the surface looks fine. A faint smell that returns on humid days, a spot that darkens when damp or a stiff patch that survives cleaning all suggest the urine sits below the surface, where towels and sprays do not reach.
Thorough extraction sometimes pulls it out. Urine that has dried in the pad may not come out of it, and in the worst case the pad, and sometimes the carpet, has to be replaced, which is a flooring job. If a cat has been marking for a while, mention it when you request a quote from Flying Carpet Cleaning NJ. The visit opens with a look at the fiber and the marked spots, and the customer hears in advance how much of the smell cleaning is likely to remove.
Why the cat keeps returning
Cats go back to places that still smell of urine, even when people cannot smell it, so complete odor removal is part of the behavioral fix. A cat that keeps going outside the litter box is also worth a call to the veterinarian, because urinary problems are a common cause. Keep the litter box clean and place it somewhere quiet where the cat feels safe.

Questions, answered
Why does cat urine smell stronger than dog urine?
Cat urine is more concentrated, so a small amount carries a strong smell, and the smell grows as it breaks down. It also stays in the dried residue, which is why a spot that looks clean can still smell on a humid day.
Can vinegar get cat urine out of carpet?
Vinegar may help with a fresh spot, but it does not reach urine that has soaked into the pad. If you try it, test a hidden corner first, rinse with cool water afterward and never combine it with bleach.
How do I know whether cat urine reached the pad?
Look for a smell that returns on humid days, a spot that darkens when it is damp or a stiff patch that stays after cleaning. Where the carpet can be lifted at an edge, a stained pad or a dark mark on the backing settles the question.
