How do you get cat urine smell out of wood floors? Act fast: blot the spot (don't rub), then apply an enzyme cleaner made for pet urine, which breaks down the uric acid crystals that cause the odour. Follow with baking soda overnight and good ventilation. Find hidden spots with a UV black light, never use ammonia, and call a flooring pro if the smell has reached the subfloor.

Why Is Cat Urine So Hard on Wood Floors?

Because wood is porous and cat urine is concentrated. Untreated urine can seep deep into the grain, causing warping, staining and a persistent odour that seems impossible to eliminate. As REALTORS® who have helped many Saskatoon homeowners, we can tell you it's one of the most common — and most underestimated — threats to hardwood floors. (If you're choosing new flooring for a pet-friendly home, see our flooring guide — waterproof vinyl plank is often the best fit.)

Why Doesn't Regular Cleaner Get Rid of the Smell?

Because it can't break down the uric acid crystals. Cat urine is far more concentrated than most other pet urine, and its uric acid crystals bond stubbornly to surfaces. Regular household cleaners may mask the smell for a while, but on a humid day the odour can come right back. Speed matters too: the longer urine sits on wood, the deeper it goes.

How Do You Find Hidden Urine Spots?

With a UV black light. Old or dried stains are often invisible. Dim the lights and scan your floors with an ultraviolet flashlight; urine stains will glow a yellowish-green colour, revealing spots you'd otherwise miss. This is especially useful in a home you've just bought, where accidents may have gone unnoticed for some time.

What Are the Steps to Remove Cat Urine Smell From Wood Floors?

1. Blot it up immediately. Use paper towels or a clean cloth and blot — don't rub. Rubbing spreads the urine further into the grain.
2. Apply an enzyme cleaner. This is the most important step. Use a high-quality enzyme cleaner made for pet urine; the enzymes break down the uric acid crystals at the source instead of masking the smell. Follow the product instructions and allow enough dwell time.
3. Try a DIY vinegar solution (optional). If you don't have an enzyme cleaner on hand, mix 1 cup of white vinegar with 1 cup of water, lightly dampen the area, let it sit 5–10 minutes, then blot dry. Don't use this on waxed or unsealed wood, as it can damage the finish.
4. Use baking soda. Once the area is dry, sprinkle a generous layer of baking soda over the spot. Let it sit for several hours or overnight, then vacuum or sweep it up.
5. Ventilate the space. Open windows, run fans or use a dehumidifier to clear lingering moisture and odour and protect the wood.

What Should You Avoid, and When Should You Call a Pro?

• Always test any cleaning solution in a hidden spot first to make sure it won't damage the finish.
• Never use ammonia-based cleaners. Ammonia smells like urine to a cat and can encourage it to mark the same spot again.
• For deep or set-in stains, repeat the process several times — patience is key.
• If the odour persists after repeated treatments, the urine may have soaked into the subfloor. A flooring professional can assess whether it needs treatment or replacement.
• If individual planks are badly warped or stained, replacing just those boards may be the most practical fix.
• Once it's resolved, consider having the floors sealed or refinished so future accidents are easier to clean up before they do lasting damage.

How Do You Prevent Future Accidents?

Keep litter boxes clean, quiet and easy to reach. Cats may avoid a dirty box, so clean it regularly. Waterproof mats around litter areas catch tracked litter and small spills before they reach your floors. If your cat is having frequent accidents, a visit to the veterinarian is a good idea, as it can signal a health issue.

Does Pet Odour Matter When You Sell?

More than most sellers realize. Smell is one of the top 5 things buyers notice first, and a lingering pet odour can turn buyers off before they've seen the kitchen. Deal with it well before listing, and use our My Selling Plan tool to build a room-by-room prep checklist. Buying a home with pets in its history?
