Remove cat pee smell permanently

We currently have one rescue kitten left at our house and the Bengal is not very happy about it! First she peed in the kittens bed. Then she 'marked' the cardboard box the kitten had been playing in. Finally she graduated to spraying anywhere she could smell the kitten. I absolutely can't stand the smell of cat urine so I did my best to clean up all these messes. I literally tried everything to get rid of the cat odor in my house.

I first started cleaning it up with the rug scrubber filled with pet stain & odor remover. That wasn't strong enough so I bought enzymatic pet odor sprays from the pet store. I also tried white vinegar and I tried essential oils. No matter what I used, it only removed the cat pee smell for a few days and then I could smell the cat pee again. I spent way too much money on this stuff! I was completely convinced that nothing but the strongest, most potent, specially made formulas would work.

I was wrong. 
homemade cat odor remover

I soon found out, I had the solution in my cabinet the whole time....and it wasn't chemical laden crap from the pet store!

Peroxide, baking soda and dish soap. Sound familiar? These are the 3 ingredients in my Best Skunk Spray Remover EVER! recipe. The proportions are a little different, but it works just as well to remove cat urine smell as it does for skunk spray! It's a lot more natural then all the artificial chemicals I was spraying in my house, plus it works better than all the other sprays and cleaners I had bought!

Remove cat urine smell permanently! 


You'll need:
Spray bottle
Bottle of peroxide 16 oz
1 Tbsp baking soda
Dish soap, just a small squirt

Pour it all into the spray bottle, replace the cap and shake to mix.

To use on fresh cat urine:
Blot wet spot with paper towels until no more moisture can be absorbed. Spray with solution till saturated. Let sit until dry. Do not blot the solution up. Once dry, vacuum or brush away any powdery residue. That's it!

If the spot of cat pee is already dry when you find it then skip the blotting and get right to spraying the solution on the urine spot.

the best cat spray remover

The best part about this solution is that it still removes the cat urine smell even if you already used something else on the urine spot!

Many commercial pet urine removers say that they will not work on old stains or stains that have been treated with other cleaners. I have used this solution to treat stains that have been previously treated with 3 different commercial solutions and it has worked perfectly every time!

Now on to the tricky part....finding exactly where the cat has sprayed. I went to walmart and bought an LED blacklight flashlight. It was under $10. Cat urine glows under blacklight!

A puddle of cat pee will look sort of like orange neon. A spot on fabric or carpet will look more like a glowy white stain. It'll glow so you'll know when you see it. Once you've found the spot, treat as mentioned above. So simple.

LED blacklight flashlight for pet stains

I have used this solution on everything...carpet, couch, pet bed and even a pair of boots and it has not left any stains or discoloration. However, I recommend a patch test if it's a particularly important surface that your cleaning.

I have not tried this on dog urine stains, but I have no reason to believe it wouldn't work to remove any type of pet odor. If you try it, let me know!

The only downside I have found is that if you don't use all the solution right away and try to use it in a few days, it doesn't seem to work as well. So mix it up fresh each time you need it. At under $1 worth of supplies though, it's inexpensive to mix up any time you need it.

This homemade pet odor remover has really helped to rid my house of pet odor...which is awesome because youngest son really wants to keep this kitten!

  1. Probably the reason it only works when you use it immediately is because peroxide is not stable, especially if you put it in a bottle that allows light in. Thanks for sharing your recipe! I'm definitely going to try it.

    3. Yes, this has worked to remove the stains from cat pee also....however if the spot was already treated with another product and that discolored the fabric or carpet, then it only removes the smell.

      Hope that helps!

    4. I should have thought about using this. I knew it for skunk smell but didn't think about it for cat urine. The only other thing I have found that completely gets ride of it is bleach but that is way harsher than this. Neat!

      Delete
    5. Yes, it is almost the same exact thing as the skunk remover except that recipe uses a bit more dish soap. Both of them work great though for removing unwanted animal odors!

  2. Doesn't the peroxide damage/discolor furnitures and carpets?

    ReplyDelete
  3. I haven't had a problem with discoloration and I've used it on several carpets, a couce and even the cat wheel. *sigh* If a surface is dirty the peroxide and dish soap combination would remove some dirt and it would appear different from being cleaner, but I don't believe it would damage any surfaces.

  4. LAST NIGHT MY CAT PEED ON A PARQUET FLOOR IN THE NEW APPARTEMENT I JUST MOVED INTO. I'M WORRIED THAT THE CLEANING MIXTURE YOU RECOMMEND MIGHT BLEACH THE WOOD. HAS ANYONE TRIED IT ON PALE WOODEN FLOORS?

  5. I have used it on wood and not had a problem with discoloration. Just to be safe, try it on a small out of the way spot first. Good luck!

  6. Is there a reason you don't rinse or blot the area after cleaning?

    ReplyDelete
    Replies
    1. I let it air dry so the solution has time to work. Rising or blotting would stop the cleaning action. It takes a few minutes for the smell to be gone completely. Once dry you can vacuum over it if it seems powdery (that's the baking soda) but it usually just dries up completely without any residue.

  7. How do u get a cat to stop peeing in the same place that u cleaned up after her? I can’t get her to stop peeing on the floor. Does anyone know what I can do? Please help.

    ReplyDelete
    Replies
    1. If cleaning the area thoroughly does not work try blocking it off for a little while. A basket placed over it, a blanket on top of it...anything so she can't actually get to that spot. If she just pees somewhere else, she may need to see a doctor to rule out a urinary infection.

      Hope that helps!

  8. I just tried this on my carpet and the smell is gone! At least to me (can't vouch for the cat). We'll see if it stains the carpet. But even if it doesn't I seriously don't care as long as it doesn't smell like cat pee.

  9. We have 2 geriatric cats with kidney disease. One cat peed in her bed a couple of days ago. I immediately rinsed the area with hot water, but wasn't sure how to proceed. It's machine washable, but based on past experience when the other cat peed on a bathroom rug a couple of times, and even a direct application of liquid detergent and a couple of machine washings didn't completely remove the smell, I thought I should try something else. I had some success putting the rug outside on a breezy day to dry, and most of the smell was gone. How would you recommend using your recipe in conjunction with machine washing?

    Replies
    1. I would completely saturate the cat urine stain with the peroxide, baking soda, dish soap solution. Let it air dry...it will probably take a whole day. Once dry, you can rewash the cat bed or just vacuum out the baking soda residue and it should be fine. Good luck!

    2. At the moment I have 4 cats, 2 special needs with urinary issues. As far as laundry,when my cats pee on a towel, their bedding, etc. I take 2 cups of White Vinegar pour it into the washing machine put the item/s in the machine, wash with hot water. I use the large/bulky setting, washes for about an hour+, when done, I wash the items again using detergent and bleach. Oder completely gone. I rescue, cat pee is the hardest to remove, been doing this for years

  11. Wow! I had no idea! It seems that often the simplest solution ends up being the best. Cat pee has got to be the WORST smell on the planet! I don't have an issue with it right now, but we now have two young kittens plus our 3 year old cat. There is bound to be some cat pee that ends up in the wrong place in the future! I will pin this so I can come back to it then! Thanks for sharing :)

    2. Best for Dog pee is white vinegar. Lots of it, repeat until the stink is gone. If the stink is in wood, then after the stink is gone and the wood is dry, seal with lacquer.

  15. I am curious as to whether or not the smell has stayed away weeks after using this mixture. I came across a web site that said you still needed to use an enzyme cleaner after because of (I think it said) uric crystals in the urine that still remain even though you may not be able to smell anything after initially using the peroxide mixture. I've unsuccessfuly tried numerous things to get rid of cat urine odor and am starting to think I'll have no choice, but to replace the carpet. I'm hopeful about the peroxide if it actually fixes the problem for good.

    1. I haven't had to reuse the solution on areas that I've treated. The cat has ignored those spots and I can't smell cat pee even if I get down to the carpet level.

  16. Try it! I had pinned this many months ago, and then a couple of weeks ago found it again when I was desperate to get rid of horrible cat pee smell on the concrete floor of our bathroom. It worked immediately, and the smell has not come back. I even tried the enzyme type cleaners previously, and they didn't work.

  19. Do you think this solution will work on stains that have set for a long time? My husband and I are interested in buying a home and we found a great house, except it smells like cat pee. There is one big stain on the wood floor in the living room, but I was thinking we could just use this solution to clean all the floors. We don’t want to get stuck in this house if we cannot remove the smell.

  20. I have a 6ftx5ft area that my 16yr cat used as her pee spot. She died several years ago and now I have kittens who scratch to cover it. I machine wash it regularly bc the smell keeps coming back so I know the carpet pad is stained too. Are you saying to saturate the area with this recipe and let it air dry?

    ReplyDelete
    Replies
    1. Yes, that is exactly right. Once it is totally dry you can vacuum up any residue rom the baking soda. The cat smell should be gone, though on such an old stain it make take 2 applications to get rid of it completely.

    I'm assuming this will work on spray too? I have a male rescue who is making my house unbearable. He gets "fixed" Feb 12 but I doubt he will stop spraying. I was researching products to buy by the gallons but will give your mixture a try. I'll probably rip up the carpets this summer but I don't want to remove the waynes coating my husband's grandfather made from his own woods.

    Wish me luck!

    Thanks

    1. Yes! This will work on both regular cat pee and cat 'spray'. Good luck with him! Most male cats stop spraying after they're fixed...fingers crossed that he does too!

  25. I have a male cat that will be 1 year soon and he has been peeing around the house but he also uses the litter box. I'm not sure exactly why since this is my first cat and he just started doing it about 2 months ago. I have used a spray for cat urine but it doesn't seem to work he goes back and pees in the spot or around it. Should the cat be kept away from the area being treated?

    ReplyDelete
    Replies
    1. It does help if they are kept away from the area while it's drying so they don't pee on it again while it's being treated. Has he been neutered? It sounds more like he's spraying and sometimes males will spray if they're not fixed. They do it to mark their territory, but most stop after being neutered.
      Hope that helps!

  30. I have a 17 year old cat who had been peeing right in front of our front door and underneath (?) her litterbox. We know she has peed there, but no indication when we use a blacklight to check. Could this be because we have previously sprayed the area with Nature's Miracle?
    Are there any specific tips for a laminate wood floor? Would saturating the area warp the planks?
    Sorry for all the questions, but I feel like the *entire* house smells like cat pee and I'm desperate to eliminate the odor!!

    1. That's odd that the light didn't work...maybe it is the previous solution you used to clean up the cat pee. I really don't know, sorry! It doesn't warp the planks, but you have to spray enough to get between them a little bit. That's where the scent will hide and the cat will continue to be attracted to that spot.

  34. This is much better than the store bought $35 spray. Only sadness is in Australia a 200ml bottle of the same 3% peroxide is $4. Still that’s much better than a $25 or $35 spray. And this is much better than the $35 spray, although I may need to use the solution again. My cat peed on my bed three times in a row, necessitating 3 visits to the laundromat. The last time I was actually in bed, bone tired, having come back from the laundromat post 10pn and she peed on the bed whilst I was in it. My fault because the velvet quilt hadn’t washed adequately in my 5kg front loader. *le sigh*

  37. Will this solution work on wood, concrete and drywall? We live out of town limits. People will dump a litter of kittens in our yard about once a year. We have a spare garage that we keep the kittens in until we can find a home for them. We do have litter boxes but there are times when they don’t make it. We have done our best to keep it clean but I believe there were times that the pee got into the wood and drywall. We want to keep these little guys safe and show them the love their owners didn’t want to provide. But the smell has gotten worse over the years. Any thoughts?
