Tenants allowed 3 cats to use under the back stairs landing as a litter box. Now they have left, we are left to clean up faeces and smell. Tried washing with borax in water..smell still there.

    Hello Denise! Concrete is porous so the urine has soaked into the concrete which makes cleaning a bit more difficult. You do want to use an enzyme cleaner and you will probably have to clean several times letting the concrete dry well in between. Here's some information: https://www.wikihow.com/Remove-Urine-Odor-from-Concrete

    Natures Miracle.....lovely stuff. It’s designed with enzymes to break down cat pee. Cat pee is oil based, so most cleaners won’t get it all out. This one has gotten the stink gone. It may take a few applications, I’ve had the best luck with it by covering the The treated spot with plastic wrap to keep the area moist.

    Try spreading baby power all over the floor. Take a broom and sweep it into the floor. Sweep it up and remove it out of the house. Don't leave the bag inside or set it down cuz it will leave the smell where you do. Then go back down and repeat the baby power be very generous with it. Hang up a bag of damp rid. Leave it set up overnight. Sweep,remove. Vacuum. Remove the vacuum. Check it the next day. That should do the trick.

    Sorry for chiming in a bit late to the discussion mate, 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.


    Registered an account only to say this:


    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: http://11.nomorecatpee.com


    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?
