  • I use a product called urine off. It works really well.

    Nature's Miracle, an enzyme product from pet stores.

    THIS IS FOR DOGS & CATS BOTH.......it is absolutely essential to use a cleaner that can break down the uric acid. When urine dries, the urea is broken down by the bacteria. This is what makes it smell like ammonia. As it decomposes further, it releases thiols that make the odor worse. (It is the thiols in skunk spray that make it SO potent and difficult to remove).

    The urea and urobilin/urobilinogin are not hard to clean. Urea, urobilin/urobilinogin, creatinine and the pheromones are water soluble (urobilin is the pigment that causes the color). Traditional household or carpet cleaners will deal with these, and this is why hydrogen peroxide, vinegar, and/or baking soda also appear (initially) to be effective at eliminating the problem. But the problem has not been solved! Uric acid and its salts have been left behind. Uric acid is not water soluble and bonds tightly to whatever surface it touches.Soap, vinegar, baking soda, ammonia, chlorine, and hydrogen peroxide (to name the most common cleaners) simply are not chemically capable of breaking down the uric acid in cat/dog pee. These cleaners and deodorizers only temporarily make the smell go away and appear to work because they do clean up the other components of the urine. But when exposed to humidity, the uric acid salts cause the uric acid crystals to reform. This process releases the smell again; not always at levels detectable to the human nose, but the cats/dogs more sensitive noses can smell it. And the scent of their urine outside of the litter box encourages many cats to continue urinating outside of the box, often with their families left scratching their heads wondering why,or dogs lifting their legs on furniture corners.

    The only thing that will break down the uric acid to permanently remove the smell is an enzyme cleaner. The enzymes break down uric acid into carbon dioxide and ammonia, both gasses that then easily evaporate. This is why it is also essential to allow the enzyme cleaner to air dry. It needs the “natural” drying time to break down the uric acid salts, allowing the resulting gases to evaporate.

    Not all enzyme cleaners are equally effective. Good enzyme cleaners are typically a bit more expensive. Cheap ones(natures miracle) will work, but need to be reapplied over and over (and probably end up costing as much as the more expensive enzyme cleaners). Enzyme cleaners this author is aware of that work well and reliably include Nok Out, Urine Off, and Anti-Icky Poo.

    Of course any cleaner needs to be used properly. Most enzyme cleaners come in a spray bottle. This is deceptive, because just spraying a light layer of enzyme cleaner over a urine stain will not result in complete cleaning of that spot. Cat/dog pee wicks(spreads seeping outward), and unless the enzyme cleaner completely envelopes all of the cat/dog pee, even it won’t work. “Spraying” doesn’t work. Dousing, pouring, and soaking are required when cleaning up cat urine.

    To properly use an enzyme cleaner on a fresh stain:

    1. Blot up as much of the urine as you can before applying anything.

    2. Soak the affected area with the enzyme cleaner.

    3. Let the enzyme cleaner sit for 10 to 15 minutes.

    4. Blot up as much of the enzyme cleaner as possible.

    5. Leave the enzyme cleaner to air dry.

    Covering the area loosely with something is always a good idea. This will not only help prevent the cat from attempting to pee on the same spot while the enzyme cleaner does its work; it will stop family members from stepping or sitting on the wet spot. Some people lay aluminum foil down over the area; other recommendations include an upside down laundry basket or an aluminum baking sheet.

    The same basic procedures apply for an old stain. But be aware that an old stain may require two or three full cycles of enzyme cleaner application (allowing it to completely dry between applications) in order to completely clean the stain.

    I use Apple cider vinegar. It removes the odor which discourages using the same spot to potty. I’ve used this with cats so I’m assuming it will work for dog urine as well. It is much harder to remove cat urine smells.

    Here's the best way to get rid of the smell of pet urine.

    Sorry for chiming in a bit late to the discussion, but I really feel like I need to add my 2 cents.


    Cats don't just pee on floors and beds because they're in pain - could be a multitude of other reasons! Most common is that male cats feel the need to mark their territory.


    As for myself, I finally found something that works for the cat pee smell in my home! A herbal mixture of sorts! I now recommend it to everyone because it works so freakin' well and we save SOO much money!


    You should definitely check it out, we don't even buy Odorban and the likes any longer :)


    What a relief to finally have gotten rid of the horrible cat pee smell, and for a decent price as well.


    One of my 2 cats (both neutered males) had taken to painting all of my walls, furniture, and anything else he could reach. I was horrified when I got a UV light. He never did that in all of the 9 years I've had him and didn't when I got him a buddy (they love each other and did so right away) but when a strange black cat started showing up outside both of my cats went nuts and the older one (9) started his wall painting, as well as the curtains out in the kitty room. I couldn't keep up with it.


    My cats are indoor cats so it's not like the stray is actually going to get in here but they both hate him (and he is weird...my neighbor's cats hate him too). I've tried cleaning with a pet urine enzyme and then spraying some "No More Spraying" but that hasn't worked.


    He's a sneaky little bugger too; he waits until he thinks I'm not looking and then does it. He's learned that the minute I see him backing his butt up to something he gets yelled at. It wasn't until I found "Cat Spraying No More" that I was able to finally get rid of this tiresome behavior. Now my house doesn't smell like a litter box anymore :)


    To be honest, I don't know too much more about it so I did a quick Google search and here's a description of the spray with a long review as well.


    No I have not been paid for this post nor do I make any commissions off of it. I really just want to help you guys out. I hope you don't mind.


    I'm based in Sweden, by the way, so you should be able to get it too.


    Good luck with the odor! It really lowers your quality of life, doesn't it?
