    Cat pee is nasty. The one thing we always insist on when we are called to remove cat urine is to remove the underlay or padding. Sanitise the floor, and back of carpet and then clean the carpet with steam extraction.

      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 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?

    Are you talking about on carpet,wood floors,furniture,just by the litter box? Any product that has any ammonia in it will add to the ammonia in the cat pee, go to janitorial supply company & buy enzyme odor neutralizer. Here's one, hard to find but works really well

    I've found white vinegar is great for removing the odor.

    Hi, I bought this recipe on-line many years ago for $5. Works wonders! Good luck!ODOR REMOVER

    16 oz. (2 cups) hydrogen peroxide

    2 tsp. baking soda

    2 small drops liquid dishwashing soap (Dawn, Palmolive, etc.)

    Place all ingredients in a glass jar or bowl. Gently stir--do not beat or shake--until baking soda is dissolved.

    If urine is fresh, be sure to blot up any excess urine with dry paper towels or a dry washcloth before the next step.

    Pour mixture over urine spot, making sure to cover the entire spot. Allow mixture to completely soak the area being treated. Do not rub or scrub! Let sit for 24 hours without disturbing.

    After 24 hours, take clean paper towels or a clean, white washcloth and blot up any remaining liquid (Again, do not rub or scrub.).

    Allow area to air dry completely. If you are treating carpet, you can vacuum over the area when dry.

    Makes 16 oz. (2 cups) of solution.


    • The strength of hydrogen peroxide required for the recipe is the 3% solution. This strength is what is commonly found at pharmacies, discount stores and grocery stores.
    • The solution is most active for one hour after mixing. Be sure to apply the solution within this time period for maximum effectiveness.
    • Do not enclose the mixture in an airtight container, or you could have a big mess on your hands! The reason for this is because when the ingredients are combined they release oxygen (Remember making "volcanoes" out of baking soda and vinegar when you were a little kid? Similar principle here.).
    • For really tough odors, you may have to treat the area more than once. Carpet, furniture and mattresses typically require 1-2 treatments. Concrete, wood, tile and other hard surfaces usually need 3-5 treatments (1 treatment per day).
    • For concrete and other hard surfaces, you want to make enough of the recipe to completely cover the stain. Pour or spray the solution on and let it soak, soak, soak. Do not mop or wipe up. Let it sit for 24 hours (depending on the humidity level, it will usually evaporate during this time). Repeat the treatment once a day for 3-5 days.
    • If you purchased the recipe to treat an oriental rug, please use extreme caution. Sometimes the dyes used in the rugs are not colorfast. We are not responsible for damage to rugs.


    • Spray bottle--A spray bottle works best for applying the solution to small areas of concrete, linoleum, or other hard surfaces. It is also the best way to apply the solution to vertical surfaces like walls, shower tile and furniture. Just be sure to thoroughly spray the area you are treating. A spray bottle is generally not the best way to treat carpet.
    • Mop--A mop is a good way to apply the solution to large areas of concrete, linoleum, or other hard surfaces. Generously apply the solution to the surface and let it soak. Do not mop or wipe up.
    • Garden watering can--A garden watering can is best for medium to large areas--indoors or outdoors.
    • Carpet cleaning machine--Just mix several batches of the recipe at a time and use it in place of the water and carpet shampoo. Don't vacuum the solution back up--just let it soak on the carpet until it air dries. While we have had many, many customers use this method without a single report of damage to a machine, our recipe is obviously not one of the solutions approved for use by the machine manufacturers. Using the recipe in your machine is at your own risk, and we are not responsible for any damage to customers' machines.
    • Chemical Sprayer--We've had a few customers use a chemical sprayer (the pump kind, not the kind you attach to a water hose) to apply the recipe to large areas. You would need to use a new sprayer (not one that has previously been used) so that there wouldn't be any type of reaction with the residue in the sprayer.


    • For mattresses, the best thing to do is to make a double, triple or even quadruple batch of the recipe--enough to completely cover the stain--and then really pour it on. Don't be afraid of saturating the mattress. The urine has gone deep into the mattress, so you need to make sure that there's enough solution to go deep into the mattress as well. The solution has to reach the urine to neutralize it. We recommend treating the mattress in the morning so that the solution can work through the day. The mattress will often be dry enough for use by bedtime.


    • For couch cushions, please follow the directions for treating mattresses.


    • For clothing and bedding, you can either spot treat or use the recipe in a washing machine. Depending on the size load you are washing, you will need to make a double, triple or even quadruple batch of the recipe and pour it in with the washing machine water. Allow the clothing/bedding to soak in the washing machine overnight. Leave out the detergent until you are satisfied that the odor is gone. Then, you can wash with detergent like normal. If any of the clothes/bedding is brightly colored, be sure to do a spot check on them first before treating them. The recipe is not safe for leather.


    • For outdoors, the recipe will work on dirt, sand, gravel, and areas with groundcover-type plants. We don't, however, recommend using the recipe directly on shrubs or potted plants.
    • If you are treating large outdoor areas or entire houses, you might want to consider purchasing the hydrogen peroxide at a higher concentration and diluting it. It would make each batch even cheaper for you. The peroxide can be bought in strengths such as 12%, 20% and 35%. The 35% solution is often called "food grade". We've had customers find higher strength solutions at cleaning supply warehouses. We've also seen it sold online in higher strengths. If you are able to acquire it, we can help you with the dilutions.


    16 cups (4 large 32-oz bottles) hydrogen peroxide

    16 tsp. (or about 1/3 cup) baking soda

    1/2 tsp. liquid dishwashing soap


    By wetting the carpet, even with our solution, it will sometimes "reactivate" the odor, making it stronger before it gets better. If you've treated three or more times, wait a few days to see what happens with the odor. Don't treat again. Usually what will happen is one of two things: 1) The smell will be lessened but not completely gone, or 2) The smell will have gone completely away.

    I've used this product with fantastic results:

    I just spray, wet it down well, and let it dry; smell disappears!

    Yes vinegar works on dog and cat urine. The dogs always go to the same spot once I sprayed vinegar and cleaned it well they stopped.
