Eliminating the smell of cat urine


Hi Everyone...I am seeking an answer on how to eliminate the smell of cat urine. I have been feeding some strays by my house and they have repaid me by spraying my screened back door. The bottom part is made of metal. I have tried everything and though the smell isn't as strong as it was, it still lingers. I have a nose like a bloodhound and everytime I open that door, which is every day, I get a whiff of it. I am trying to be as environmentally conscious as possible. Any suggestions???

I recommend Anti-Icky-Poo. Weird name, but it works, and smells nice. It uses live bacteria and enzymes.


Hi when my cat or dogs would have an accident or act up and leave me a nice smelling mess I use a product called Sol U Mel.(I get from Melaleuca) It contains no ammonia, no phosphates, no chlorine and is made from all natural, biodegradable products. It has tea tree oil in it. I love it and use it for several different things, room spray, spot remover. When using with a cats urine I use full strength, let it sit and soak in. Then wash with it and another time just because that is me. Now if you have paint on your screen door you might want to check that it will not remove it. Also do not forget the cement or what ever the material is at the bottom of the door that could be where is it coming from as well.


Maybe try spraying some Bi-O-Kleen BAC-OUT odor and stain eliminator on the door. It has a lime smell and uses enzymes to clean up bacteria and odors. They also sell enzyme sprays to remove odor and sprays that deter cats(from the area sprayed, like your door)at the major pet store chains though I'm not sure if there are questionable ingredients in those. I read online that vinegar and orange peels will deter cats naturally. Vinegar also cleans great and might help you get rid of the smell and keep it from coming back. You can find BAC-OUT at natural food stores or online.


Hello Yvonne.

I have three indoor cats, who have given me plenty of opportunities to try cleaners for cat urine. When our newest cat adopted us, she marked everything in the house--including the sofa! I searched and searched online for answers, and finally found one that worked for me. Baking soda and hydrogen peroxide! Simply mix the two into a paste, and add water if needed. It will dry and can either be wiped off or vacuumed. All other cleaners left a tell-tale odor, but this is the best.
I hope this works well for you.

I've used "Nature's Miracle" for when my dog has had accidents or gotten sick in the house when he was younger (always my fault for forgetting!) It 's an enzyme-based odor-remover and can be found at pet-stores.

They also make a skunk-remover, but I don't think it worked as well as the home-made formula (hydrogen-peroxide, dish-soap and water).

Eliminating the smell of Cat Urine:

We found a product called Neutroleum Alpha. Made by: Pocatello Supply Depot, 238 Dillon, Pocatello, Idaho 83201. It says on the bottle it is effective on "Odors arising from penned animals, as in a laboratory or Kennel, skunk spray contamination, or rotting carcass are examples of odor problems controlled by Neutroleum Alpha".

We have used it on dog urine spots on the carpet after we cleaned the carpet spot with spot cleaner, and there is no trace of the odor after.

The bottle doesn't show what the contents are, but if you contacted the company you could find that out.

I have also used tomato juice to remove skunk smell from a dog, but it didn't take out all of the odor. I know that Baking soda will remove odors from the refrigerator and is a good cleaner also. We have also used white vinegar to clean our laminate floors and it actually will clean very well, and after a while and the vinegar smell is gone, it seems to have freshened the air and removed odors that were there prior to use.

Try spraying the door with straight vinegar. I used that when my neighbor's unneutered cat was spraying my door to get my cat's attention. It seemed to smell better after a couple of days. Just make sure the cats don't come back and repeat the spraying. Usually they don't like the smell of the vinegar. They also don't like the smell of citrus, so if u have any leftover peels u can place them around the door.

I have 4 "children" [3 cats and a husband :-)] and I'm also in recovery from FMS, CFS and MCS. I too have outside visitor kitties, and they too occasionally leave their "feline calling card" on my back door kickplate. I discovered a product that works very well for me.

XO Corporation makes an organic, biodegradable cleaner and an odor neutralizer especially for animal messes (but of course you can use it for other things). They make ready-to-use and concentrated forms of their products. It's great for scrubbing cat boxes, washing cat towels, etc.

For the outdoor smells, I simply spray it on generously and allow it to dry on its own. I've only read the label on this product because I've been unable to download the MSDS (crabby computer), but I use it with great success (odors are completely gone) and I've have no personal reaction to it.

You can read about their cleaners at The website has a list of distributors. I get mine from through a vendor by the name of KV Vet Supply. Good luck to you, and keep loving your feline babies - especially the outdoor/feral ones who need it most!


There's a product called Nature's Miracle which was highly recommended to me last summer by a visiting nurse to eliminate cat urine smell. I was able to purchase it at our local feed store (it has all kinds of great products for animals and their humans). The ingredient list shows: Water, Natural enzymes, isopropyl alcohol and natural citrus scent. To me it smells like some commercial liquid laundry detergents smell, but very much on the light side. As to its effectiveness, I cannot say, as the cat spray issue ended up not being a problem after all (don't know how that works!).

COMMENT FROM DEBRA: Isopropyl alcohol is generally a petrochemical ingredient, but check with the manufacturer to see if they used a plant-based alcohol.

strong vinegar?


I share my home with many rescued kitties, and over the years, spraying and inappropriate urination (as it's euphemistically labeled) have sometimes been a problem. I've tried many products, and in my experience, some stuff called Anti-Icky-Poo Live Bacteria/Enzyme Solution works incredibly well.

Here's how the manufacturers describe their product: This exciting new bio-chemical removes odor by consuming its source, the way nature does it, safely but much quicker. Engineered to eradicate urine, it will digest any malodorous decay including liquid or dried fluids from vomit, feces, rotten vegetables, fish, milk, dead bodies, skunk musk and more, even smoke.

Their website is; they also sell through, and the cost is similar at both sites. I discovered Anti-Icky-Poo several years ago on the website; they also sell it, and they provide a wealth of information on cat behavior. Other than internet sources, I believe some veterinarians sell it; however, the one vet in my area who carries it also jacks up the price considerably.

I really cannot recommend it highly enough. Good luck, and bless you for feeding the strays.


We are often asked to get out the smell of pet urine in our green carpet cleaning business. In both our cases, the residual problem after cleaning is the odor. The urine smell, and the phremones, etc. On a retail level, I like BioKleen's Bac Out, it has live enzyme cultures and is effective. You can spray this undiluted 3 times a day and let it dry and that should take care of it. You can also augment with a combination of tea tree oil and graprefruit essential oil and that should help strip the lingering pheremones as well.


I use a totally green enzyme cleaner from Clean Environment Company. You first need to shake it up to activate the enzymes, then spray it on the affected area. I have used it on clothes, rugs, around the toilet, really any surface that is washable. I once had a scarf that got saturated...I soaked it in the enzyme cleaner for several hours and was grateful for the results. No odor at all. I love those little enzyme guys! Charlotte Lovett


Does anyone have experience with treating odor from HUMAN urine stains? Specifically, I have an elderly incontinent father, living in a very small apartment that smells horribly of urine. Would the products mentioned here be effective, or is adult male human urine too different in constitution from cat urine? Nature's Miracle doesn't seem to help. Thanks!

I want to say thanks to all that replied to my SOS call for the cat urine smell. So many good ideas. I am going to try the Anti Icky Poo. It's hard not to say that without laughing. I just placed an order for it and hopefully I will have it by the end of the week and go from there. Thanks again for all of your ideas. And I will continue to feed the cats, though I'm trying to catch them so that I can get them neutered/spayed. So wish me luck. They have eluded me so little boogers!! Take care everyone!!

Although enzymes are a good idea, we have had luck with peroxide and vinegar...not together. While doing remodeling, found a spot in the back of a closet that smelled really bad when the floor was ripped up. We poured on peroxide and after shopping for a few needed items, came back home and could notice no smell at all.

We have a large cat...and old (20 years) who can't get in the litter box (his balance isn't all it used to be.) He has permission to use a small washable rug beside the cat box. Then we wash with a vinegar rinse and use a squirt bottle with 1/2 vinegar and 1/2 water and a rag or paper towel to clean the area where the rug was. We also found upstairs that he will use a plastic pan (for under washers) with a doggie pee pad. It has a very small lip he can get over. Use 1/2vinegar/1/2 water for cleaning and it doesn't discourage him from using that pan. If vinegar relly does discourage cats....apparently the pee pad makes up for that.

For about a year, I was cleaning a "no-kill" cat sanctuary. There were always about a dozen rescued cats there, and several were feral and had "accidents" outside the litter boxes. I mopped every week with a bucket of water to which I added some white distilled vinegar, a squirt of dishsoap, and a couple drops of lemongrass essential oil. I realize that there is a lot of discussion about cats and essential oils. In the time I was there, there was never a reaction to the mopping I did. Cats usually perched on their cages (they were allowed to roam unless they were so antisocial that they picked really bad fights) and watched me mop. I used an all purpose green cleaner that I made consisting of 50-50 white distilled vinegar:water, lemongrass essential oil, and a tiny shot of dishsoap. The floor was painted wood, and the counters were too. The space was very nice and refreshed when I left. Alas, the litter boxes were in continual use, so the fresh feel didn't last very long!

Hi...this is Yvonne...the one who asked for help on the cat urine smell. I received the Anti Icky Poo and all I can say is...IT'S FANTASTIC!!!! I sprayed down my door inside and out...the threshold...the patio where the cats eat...pretty much everything and there is no smell left. Thanks to all who responded and to those who are reading this for the first time and may have the same problem...try the Anti Icky Poo. I don't think you will regret it. You can get it on for a lot cheaper than most places where asking for it. Good luck ladies and take care.

I read the posts and suggestions regarding getting rid of cat urine odor with great interest! I have done most of what's been suggested to a corner of one of the rooms (about 100 year old house, parlor sized rooms, then kitchen, then bath, and a "mudroom/sunporch/laundry room" are all the rooms downstairs) with a hardwood floor.

Nature's Miracle, baking soda in various combinations in a paste, I think I did vinegar to make the paste at one time, with washing soda, all sorts of things, can't remember half of them right now) to the wood flooring that was here when I moved in...thought I'd gotten it out, bought a new carpet, and my altered female rescued kitty girl went right over to that corner of the room and sprayed all over the new rug, the floor, etc.

I have been considering sanding to try to "remove" the smell from the wood that way, but really the floor looks bad from the old carpeting's pad (I took it up myself) being stapled to the wood, I removed them on my hands and knees one at a time and there are many holes in the lovely but stained wood, so sanding may help the wood's appearance and remove? the urine, but I don't care so much about the floor's appearance, as the floor is very cold without a carpet in the winter, I'd like to keep the carpet down.

I will try the Anti-Icky Poo before I throw the rug away, and on the wood flooring underneath. also has those pheromone products, but I'm presently unemployed and those are expensive and it's not a territorial thing, it's her reacting to what is there on that corner of that floor, as she does not go anywhere else, with a temporary exception, except her box. Anti-Icky-Poo is supposed to be great, and here's someone, even also in PA, who's actually used it and having success!

Oh, and I bought and tried Zero Odor, very expensive, no help. I did not know that tea tree and grapefruit essential oils would eliminate pheromones, and despite all I have also read about essential oils and toxicity of them to cats, I use oils on me all the time, with no apparent harm to her or my former kits, and while I wash my hands before petting my cat after the use of essential oils, it's not hard to keep them off of her, because if I forget to wash my hands and go to touch her with a lot of essential oils on my fingers/hands, she moves away from me very very quickly, so I'm almost hoping they will keep her off that corner of the room if I use them. She's 14 years old in August this year and very healthy except for dandruff that nothing seems to help and I would like her to continue healthy...but I'm going to start with the Anti-Icky Poo.

Thanks for the tips and suggestions and 'tricks' everyone posted! I've really been through it with this...she does not spray anywhere else, except on my former foster child's belongings in the room he used to sleep in, she did not spray the carpet in there, or anything else, just some of his belongings. I also had roaming ferals spraying my front metal screen door this spring, too, so now I have a way to help that smelliness, which has receded with a lot of rain, but they may be back again!

Needless to say, my kitty's a behavioral challenge who is anxious, accepts touch only from me and then to a limited extent after 7 years of working with her, and she was released to me as a no-other-pets and no-children-rescue-forever home, which was the case when I first adopted her - but spraying everywhere wasn't ever a problem, we're in our third home now, just over the already "offended" area of floor. I took that child four years after the cat's adoption, only because he had no where else to be at that time, except traditional foster care, and his family member did not want that and asked for my help. For the most part, I think we "survived" him being here and her "putting up" with and tolerating him rather well for the two years he was here, there are only one or two other humans she tolerates to some extent. She was in a kill shelter when she was rescued and no one, including the rescuer, could get near her without risking being bitten, but she and I are friends, she's my little ornery love, and she's staying right here, so I need to clean the cat urine stink out of my house!

Thanks for the info! Any specific methods for original old hardwood flooring and removing urine (short of ripping up and replacing the floor, no $ for that right now, either!) please let me know by posting here! Kilz painted on that section of flooring has been suggested to me, but I'm told it will be white forever after, I don't want to do that until I find out there is no other way.

distilled white vinegar sprayed full strength on areas where cats have sprayed will immediately kill that foul odor and the vinegar smell goes away quickly.

POSTED BY JUDY :: FLORIDA USA :: 06/16/2008 11:35 PM

So many good resources have already been posted by readers, but will add ours - we have used a product called "Odormute" which was originally designed to take the "skunk stink" out of anything sprayed by a skunk! So it works very well for cat urine.

The product works with enzymes and so they caution one should not be spraying chemicals trying to eliminate the smell first, as that will cause the enzymes to not work as they should.

This product is available through Ryter Product Catalogue,1-800-643-2184. We haven't had cats spraying for about two years, so if somehow that source isn't at that number any more, just type in "Ryter's Original Enzyme Formula Odormute" - says it eliminates Organic Odors.

Can be used in kennels, dog runs, catteries, stock farms, manure piles, etc. Cannot harm humans, pets or plant life. you mix the powder with water and spray or sprinkle over area. One ounce makes 10 gallons of solution. Says it is nationally advertised and sold throughout the world!

It comes "unscented" and "lightly scented" and there are different sizes of boxes of the product one can order. We used to have to use it pretty frequently and so bought the 15 oz. box so we woudln't have to keep ordering over and over. It keeps well in its own box, or in a ziploc bag!


When I had an issue in the family room when our cat sprayed, I used a 1 part baking soda to 2 parts of water that needed to be stirred to dissolve and poured it into the carpet to get it into the padding and sub-flooring as well. I did this two times and my bloodhound nose could smell nothing! The baking soda leaves a residue that is easily handled by vacuuming. Voila!! Before this, I spent plenty of money on store and vet products that didn't work as good as our inexpensive baking soda.

A product called BAC-OUT by a company BIOKLEEN is the ONLY thing I have found that completely eliminates cat urine. You can find it online or in a natural whole foods store. Also, Raleys carries the product. It is biodegradable, non toxic, smells good, and is concentrated so as to dilute it. I put a mixture in a spray bottle and the cats stop spraying(yes they are fixed) for over a year. I rescue abandoned cats so I do a lot of laundry and have spent many dollars and tried many products. i swear it is better than nature's miracle which some people swear by. Even my mom agrees, she's a bleach queen, and was hesitant, now it's the only thing she uses. Try it, I have spent so much time and energy looking for something, I just like to pass it on. There is nothing like cat urine. Good Luck!

It's and it 6-8 dollars for 32 oz again you dilute it like 1 part bac-out to 3-5 parts water, but you can find your own ratio-depends on how soiled etc. Often I put it from the bottle on the stain and throw it in wash. Works like a charm!

... haven't tried it myself, but sells something called zeolite crystals that are odor absorbing... you can get little bags for use around the house, or truck loads to use in horse stalls!

I am actually trying to find a safe but effective way to elminate the smell of cat urine from my Clothes closet. I cleaned the walls, took up the carpet and padding, cleaned with several products, but the smell still lingers. Now it is time to get tough. I need this closet back! PLEASE HELP!

I've been told that using a solution of water with high concentration of NON BUFFERED Vitamin C powder is effective against urine. Test in small spot first.

Clorox removes the smell of baby's urine from diapers. A non sensitive person would need to apply a solution of water and the clorox to area, leave on for a hour or so, wash off with very hot water, if necessary put heater in area to further dissipate chlorine odor.

From the web:

Home Remedy for cat urine smell. This is a great recipe for removing cat urine odor from carpet. Start by blotting up as much of the urine as possible with old rags or paper towels. Next mix 3 parts water with one part vinegar and saturate the spot.Dry thoroughly using the same method mentioned above. Once dry, sprinkle the area with Baking Soda. Next mix ĺ cup of 3% hydrogen peroxide solution with one tsp. dish detergent and sprinkle over the Baking Soda. Try this first on a small inconspicuous area of the carpet to make sure the hydrogen peroxide wonít discolor your carpet. Next, use your fingers or an old brush to work the Baking Soda in. Iíve used an old hairbrush with little bits of plastic over the tips with good results. Allow this to dry and vacuum it up. If thereís still a slight odor when done, lather, rinse and repeat.

Bleach your cement floors and bare walls. Although this method is widely disputed because of the deadly reaction bleach has with ammonia (which is found in cat urine), if you go about it carefully, it can be an effective way to kick the urine smell out of your life for good. First, wash the soiled area with any appropriate cleaner you have that DOES NOT contain ammonia. Once clean, wipe the area down with fresh water to remove any residue left behind by the cleaner. Next, do it again. I know it sounds laborious, but trust me, this works. After your second washing and wiping, employ your bleach. In a clean spray bottle you can pick up from the beauty section of any Target store, mix a 10:1 water to bleach solution. Make sure the area you are cleaning in is well ventilated, put on some rubber gloves and get to work. Spray on lightly, let sit for about 30 seconds, and wipe off with a clean damp rag.
