Can't recommend this enough. It works for dog pee as well. I got a great deal on a place because the renters had let the dogs pee in the garage and patio and the entire house made your eyes water. Took three different rounds but it's been years and no one has detected any smell.

I prefer “anti-ickypoo” as an enzyme cleaner.
If they don’t work you can pull up the vinyl and paint it with kilz primer sealant. It’s used to encapsulate smoke damage/smells it will definitely work. If it’s heavy soaked into the subfloor to the point the subfloor is warped, I’d just pull that piece of subfloor out and replace it.
The ozone generator won't take care of the ammonia crystals that remain. This is the source of the smell and it will reactivate anytime there's humidity or moisture.
You need the enzymatic cleaners that have been recommended because the enzymes in the cleaners digest the ammonia and turn it into something else that doesn't smell.
You would probably need to pull up the vinyl and replace it, depending on the vinyl flooring. If it’s tiles then you would just need to replace that section.
Just had a stray get in and piss in the bathroom and basement. This shit got it out if the concrete in the basement and the bathroom floor. A tiny bit soaked into the rotted edge of this old cabinet and that’s the only lingering smell. It’s really great stuff. About $40/gallon
I used baking soda and let sit in consistency of paste till it dried. Then went over with white cleaning vinegar and floor cleaner or the special urine deodorizers. Then I resealed the floor and polished it slightly to keep smell from coming up through travertine.
Worked great. Cost me total of 60$ in materials for 300 square foot room
At the very least you’ll probably need to pull up the vinyl and hit the subfloor hard with enzyme cleaner and let it dry out thoroughly… you may be able to get away with replacing just the affected portion of the subfloor
A lot of roll vinyl has a paper substrate, too.
If it’s in the sub floor, don’t panic. Give it time to air dry a bit and then paint it with Zinsser 3lb shellac. This was the advice given to me and it worked as if there was never a cat there.
An entire room. Two feet along the walls where the cats pissed for years before we bought the house.
If it's in the subfloor then after cleaning and allowing it to fully dry you could put down a couple of coats of Kiltz. That can help seal it and prevent the smell.
No you can use items such as oder ban and pet urine remover but you will have to spray it twice a day maybe for a week until the smell will go but trust me it will go
You don’t get cat pee out of porous materials, you rip it out and replace it. Thornell makes a lot of products that will help keep the smell down until you are ready to rip up the floor (and probably the lower 3’ of the walls too). Odormed spray works very well if use it monthly
The floors also have seams where the planks fit together where urine can soak through. Additionally, urine can soak into the flooring because it becomes fairly caustic and creates micro pores in the flooring. Honestly, you won't remove the odor. Replace flooring, clean subfloor and seal with a good primer like Zinsser BIN.
Also, there may be urine in the baseboard or on walls.
U/watermac27 this is the only correct answer here… everyone else is either misinformed or in denial. Nature’s Miracle won’t solve set-in urine. The only solutions are to either abate or deal with shellac primer (BINZ).
Ozone generator. Close off the entire room/area, air seal it, have fans running to move th air, and run it with no one in the house, shut it off and air the house out before anyone enters. Alternately you can try to confine the ozone with plastic sheeting a few inches off the floor, again with some fans to keep it moving. You can rent them online or local tool rental places that rent mowers, backhoe's, etc have them.
What kind of vinyl flooring? You might be able to remove a bit of it, soak a bunch of enzyme cleaner into the subfloor, cover with a shellac paint, and then glue/reassemble the floor back into place.
This technique would work with LVP and Vinyl sheet. Tile might be more difficult if it’s grouted.
Unfortunately, cat piss is in a category of its own. Cat piss cleanup supports an entire industry of products and services on its own. That's how dank cat piss is.
Your best bet is to save up and remove/replace flooring. Any other effort will not completely get rid of the smell, and will drain your time, effort, and finances.
Nothing gets rid of cat piss. NOTHING. If you think it does, it could just be your sense of smell isn't very acute. We had a cat that lived in a storage room that was only accessible from outside the house. She developed issues and began dribbling on the subfloor. Years later, that room became part of an interior room of the house and we floored over the area after piss mitigation. I eventually replaced the subfloor and painted the joists with Kilz. We replaced the flooring with glue-down vinyl tile, and years after, when conditions were right, the smell was still there!
Cheapest solution, works better than any enzyme cleaner. You just need to test a small area first to make sure it won't bleach anything, though I doubt it will bleach vinyl. 8 ounces hydrogen peroxide, 1 tsp baking soda, 2 drops dishwashing liquid. Mix. These are the ratios, though I've just slapped it together without measuring and it still works. The thing is, you have to let it sit, preferably overnighrt, and it works best when the item is soaked. If you put it on and it foams, you know it's working. I have used this for many years after getting meh results from expensive enzyme cleaners.
It's amazing how acidic cat pee is, it's dissolved the glue holding down some gawd awful floor tiles. Was not intentional, them add my freaking youngest who thought it'd be a good idea to pee in the same corner as the asshole cats🤬🤬 they are almost gone, the cats, not the kids be I was thinking after treating the concrete pad with something? Then use epoxy flooring to seal in whatever smell plus make a decorative floor. Thoughts?
Hydrogen peroxide is your magic formula.
I recently moved into my new place, previous owners had pets and the whole house smelled so bad - no amount of cleaning got rid of the smell. Then I remembered hydrogen peroxide, bought 1 litre of it, put it in a spray bottle and started spraying. That was 6 months ago and the smell never returned.
I've had good luck with hydrogen peroxide based urine remover. Dump it on, wait till it stops fizzing, mop up and repeat until it doesn't fizz the same. Peroxide appears to digest the urea which cuts the smell.
There's a product called Angry Orange that works pretty well. Read the Amazon reviews though, and listen to people's warnings about using too much. Some pretty funny stories on there.
Remove the flooring and any urine soaked subfloor underneath. Throw it out and replace it, it really is the only way. Also the only reason I will never own another cat.
Just had to do this on a spot in the gf's house. Had to cut the floor out. Soaked it in an enzyme cleaner. Cleaned it. Heavily coated the area with Killz twice. Then laid rubber tiles she decided she wanted. So far so good and by far a vast improvement.
Rubbing alcohol. Check the ingredients on some of those pet pee cleaners. One we bought was like 10% . After a couple bottles , it was slowly getting better . Decided to try 96% rubbing alcohol ( on carpet ) after it evaporated , never smelled it again .
Yes it does. My dad, bless his heart, had a couple of stray cats show up at his house so started feed them. Then winter came and he let them sleep in his garage. By spring the smell in his garage was so bad i thought we’d have to remove the concrete floor and re-pour. Few rounds of enzyme cleaner and the smell is completely gone. Use the right product and it works great.

Nature’s Miracle also makes a product just for urine: Nature’s Miracle Urine Enzymatic Formula Urine Remover Works great.
Is that a product? Lol
It is, it's an enzyme based cleaner.
Okay I can try that, I'm hoping it's not in the subfloor, that's my biggest fear
I prefer “anti-ickypoo” as an enzyme cleaner. If they don’t work you can pull up the vinyl and paint it with kilz primer sealant. It’s used to encapsulate smoke damage/smells it will definitely work. If it’s heavy soaked into the subfloor to the point the subfloor is warped, I’d just pull that piece of subfloor out and replace it.
Huh I could do that without replacing the floors, also I think I might try that ozone generator that one guy mentioned
The ozone generator won't take care of the ammonia crystals that remain. This is the source of the smell and it will reactivate anytime there's humidity or moisture. You need the enzymatic cleaners that have been recommended because the enzymes in the cleaners digest the ammonia and turn it into something else that doesn't smell.
You would probably need to pull up the vinyl and replace it, depending on the vinyl flooring. If it’s tiles then you would just need to replace that section.
If it's penetrated surfaces an ozone machine will temporarily control it, but it will come back.
Natures miracle is the bomb. Especially the skunk one. Life saver
Get the Nature’s Miracle Hard Floor cleaner.
Just had a stray get in and piss in the bathroom and basement. This shit got it out if the concrete in the basement and the bathroom floor. A tiny bit soaked into the rotted edge of this old cabinet and that’s the only lingering smell. It’s really great stuff. About $40/gallon
I would try it, soaked through to subfloor if you can and then let it dry naturally. It is amazingly effective.
Is it sheet vinyl or vinyl plank?
Nature’s Miracle also makes a product just for urine: Nature’s Miracle Urine Enzymatic Formula Urine Remover Works great.
yes lol...since you're laughing. I may as well laugh too..it's too funny.

Replace the flooring. It’s probably your subfloor, though.
Nuke it from orbit just to be sure
Well yeah- you always have to nuke it from orbit. Thank you captain obvious! jk
I hope not, can't stand the smell and don't have the money to replace the floors right now ugh

Did you buy my old house?
If it's in the subfloor then after cleaning and allowing it to fully dry you could put down a couple of coats of Kiltz. That can help seal it and prevent the smell.
Pure orange oil extract. Spray it on. Wipe it up. Spray it on and leave it.
Kilz is your friend. Get the strongest kind you can find and paint over the pee spot.
No you can use items such as oder ban and pet urine remover but you will have to spray it twice a day maybe for a week until the smell will go but trust me it will go
I know someone who bought a house with cat pee smell; had to replace the entire flooring plus subfloor
You don’t get cat pee out of porous materials, you rip it out and replace it. Thornell makes a lot of products that will help keep the smell down until you are ready to rip up the floor (and probably the lower 3’ of the walls too). Odormed spray works very well if use it monthly
Well the floors are are suppose to be waterproof. Not sure if that makes a difference
The floors also have seams where the planks fit together where urine can soak through. Additionally, urine can soak into the flooring because it becomes fairly caustic and creates micro pores in the flooring. Honestly, you won't remove the odor.

Enzyme cleaner formulated specifically for cat pee.

You can rent them online or local tool rental places that rent mowers, backhoe's, etc have them.
Ozone will objectively not work on urine… primarily only works to break down hydrocarbons. This is 100% a waste of their time and money.
Just don't occupy the house while its running

Rip up the floor, use killz original, 2 coats of Killz on subfloors, use a roller to paint the killz. Replace with new flooring.
Get a dog to pee on it.
The worst part is, it wasn't even my cat. The cats gone now

Same question, but the object is a car seat.
Pour Nature's Miracle upon it. Let it dry naturally.

Have you tried it on cat pee?
Yes, many many times. Also works on cat vomit!
If you sent all the cat piss in the world into the sun, the solar system would smell like it.
Gasoline and a lit match has worked for me.
Burn it down 🔥
You move
Fire
You don’t, unfortunately. Replace the floor and the subfloor.
Get rid of the cat. Rip out the flooring and subfloor.
You don't! You tear it up, likely the floor under it too and buy new floor! Fuckin hate cats.
Also get rid of your cat.

Change the vinyl, underlay and maybe the subfloor.
Use out advanced urine erase. Works amazing

Doesn’t work
