As a pet owner, you love your furry companions, but not so much the messes they can make. Cat urine in particular can leave behind a stubborn, unpleasant odor, especially when the accident occurs on carpet. Thankfully, there are steps you can take to banish even the most persistent cat pee smells from your home.
Why Cat Urine Smells So Bad
Cat urine contains something called volatile organic compounds or VOCs. These are chemicals like acids, alcohols, aldehydes, ketones and more. VOCs give urine its characteristic odor, which is unpleasant to humans.
Several factors make cat urine especially pungent:
It gets worse over time: The older the urine, the more time VOCs have to build up concentration and smell.
Tomcats spray to mark territory: Unneutered males spray urine to mark their domain and signal other cats. This urine is extra stinky due to testosterone.
Older cats have weaker kidneys: Senior cats have poorer kidney function, leading them to excrete highly concentrated, foul-smelling urine.
Cats pee outside the litter box: Urine sitting on fabric or carpet has more VOCs than cat pee soaked up by litter.
So when your cat has an accident on the carpet, it’s important to act quickly. The longer the urine sits, the worse it will smell as VOCs accumulate.
How to Remove Cat Pee Smell from Carpet
When tackling cat pee smells in carpet, follow these steps:
1. Blot up the urine immediately
As soon as you notice the accident, blot up as much liquid as possible with paper towels or a clean cloth. Avoid rubbing, which can spread VOCs deeper into the carpet fibers.
2. Rinse with water
Rinse the area with cool water. This will dilute any remaining urine and VOCs on the surface. Use towels to soak up the rinse water.
3. Apply an enzymatic cleaner
Enzymatic cleaners work wonders for eliminating cat urine odors. They contain natural enzymes that break down the compounds in urine that cause bad smells. Thoroughly saturate the soiled area, allowing the enzymatic cleaner to soak in for 5-10 minutes.
4. Blot and rinse again
After letting the enzymatic cleaner sit, use towels to blot up as much liquid as possible. Follow up by rinsing with clean water and blotting again.
5. Allow carpet to dry
It’s crucial to let the carpet dry completely before your cat steps on it again. Place fans nearby to speed up drying time. You want all moisture gone so VOCs don’t continue to concentrate in the carpet backing or padding underneath.
6. Re-apply as needed
If any hint of odor remains once dry, re-apply the enzymatic cleaner. Old or heavy urine stains may require multiple applications and dry cycles. Persistence pays off!
7. Discourage re-soiling
To prevent kitty from peeing on the spot again during treatment, cover it with upside-down laundry baskets or foil. Once the carpet is dry, place treats and toys in the area to re-direct good behavior there.
Helpful Cleaning Products and Tips
Use an enzyme cleaner formulated for pets: Look for enzyme cleaners made specifically to combat pet messes. They’ll be stronger and more effective than typical carpet cleaners. Nature’s Miracle and Bissell Pet Stain & Odor Remover are excellent options.
Avoid ammonia or vinegar: It may be tempting to use household products like ammonia or vinegar to clean cat pee in carpet. But ammonia can make odors worse since it’s also found in urine. Vinegar has limited effectiveness on old, dried urine stains. Opt for a powerful enzymatic cleaner instead.
Dry carpets quickly: Things like fans, dehumidifiers and sunshine can speed up drying time for faster odor removal. The quicker you can dry carpet after cleaning, the less chance VOCs have to re-concentrate.
Consider replacing padding: If stains have soaked through to the padding beneath your carpet, it may need replacing. No amount of cleaning above will get rid of odors trapped in saturated padding.
Hire a professional: For severe or chronic urine issues in carpet, call in a professional carpet cleaning service. Their industrial machines clean deeper and more thoroughly than rented units. Ask for services specially designed for pet stains.
Clean accidents ASAP: Try to catch pee messes right after they happen. The longer cat urine sits, the harder it’ll be to get smells out of carpet later. Aim to start cleaning within minutes if possible.
Pre-treat stains: Using an enzymatic cleaner or pet stain pre-treater before steam cleaning carpets can boost your results. Pre-treating allows cleaners to start breaking down VOCs earlier.
Check for hidden stains: Use a UV blacklight to spot old or dried stains you can’t see. Surprise stains you uncover can then be pre-treated to avoid leaving odors after steam cleaning.
Control re-marking: If one cat pees on a spot, other cats may smell remnants of urine and re-mark the area. Getting rid of all odors the first time controls this behavior.
Re-clean troublesome areas: For spots that keep smelling pee-like after cleaning, go back and re-apply your enzymatic cleaner. Let it soak deeper into the padding and backing below the carpet surface to banish odors once and for all.
Common Questions About Cat Pee and Carpet
Here are answers to some frequently asked questions about eliminating cat urine smells from carpet:
How do you get old, dried cat urine stains out of carpet?
Pre-treat: Saturate the area with an enzymatic cleaner and let it soak in for 10-15 minutes to start breaking down old VOCs stuck in the carpet.
Steam clean: Use a carpet shampooer to deep clean urine-soaked areas after pre-treating. The hot water and suction lift stains to the surface for removal.
Dry quickly: Set up fans to speed dry time. The longer moisture lingers, the more VOCs that remain trapped.
Repeat if needed: You may need to pre-treat and steam clean multiple times for stubborn, dried urine stains.
How can you find all the urine stains in a carpet?
Use a UV blacklight in a dark room – old stains will glow fluorescent under the light.
Get down and sniff around on hands and knees – it’s easy to pinpoint spots this way.
Check along baseboards and walls – stains often go unnoticed here until they’ve dried.
Inspect behind furniture – cat pee can soak into the carpet under chairs, couches and more.
What cleaning solutions work best for cat urine?
Enzyme cleaners designed for pet stains work best. Look for ones containing multiple strains of live enzymes to handle all the compounds in cat pee. Vinegar and DIY cleaners often don’t have strong enough enzymes. Invest in a specialty pet enzyme cleaner for the best results.
How can you keep a cat from peeing on carpet again after you’ve cleaned it?
Place foil, upside down laundry baskets or plastic sheeting over the spot to block access while carpet dries.
Sprinkle catnip or treats over the area to encourage happy, non-peeing behavior there.
Use a pet-safe repellent spray to deter additional accidents.
Address underlying issues like litter box problems so kitty pees in the proper place.
Clean messes ASAP so urine doesn’t have time to soak deep into carpet backing.
The Takeaway on Eliminating Cat Pee Odors
When cat urine lingers in your carpets, the result is a stubborn, unpleasant smell that seems impossible to conquer. By acting quickly and using the right products and techniques, you can successfully banish even severe pet pee odors from carpeting in your home. With a bit of elbow grease and pet-specific cleaners, you can keep your home and carpets fresh, clean and free of any hint of stale cat urine.
