How can I get the smell of cat urine out of my carpet?

I've always had good luck with the pet enzyme tablets, you mix with warm water, its much stronger cause its fresh, why pay for water plus who knows how long that stuffs been on the shelf. I put it in my carpet cleaner water reservoir. I've done this for multiple clients and myself when a friend brought her cat over, I tried everything on the market until I found the tablets. The active ingredient is the CO2, and when you plop the tablets in the water you will see bubbles forming. I am also a big fan of the ultraviolet flashlight as it lets me find all the spots..... sometimes you don't realize they have sprayed on the wall, urine floresces a bright color so you can find it. Turn out the lights, close the curtains or wait for night. https://www.amazon.com/Jackson-Galaxy-Stain-Eliminator-Fizzion/dp/B019YMYNR0/ref=pd_sim_199_6?_encoding=UTF8&psc=1&refRID=5C6NR1ZTEC6J9GF93FK6

You need to throw the carpet away. The stink will never go away. Wash underfloor with commercial product especially for pet urine smell. Soaking with vinegar might help.

I wish I had some good news. I have rescue cats, now 2 of them. One has apparently ALWAYS been a carpet wetter but we weren't told. She has managed to nearly ruin 2 oriental rugs, and all of our pale wall-to-wall carpet will need to be replaced. I, like you, have tried everything with no luck. Finally we have had some modest luck with the "Woolite Pet Urine Eliminator PLUS Enzyme action." It's easy to use and seems to be fairly successful IF YOU GET TO THE SPOT RIGHT AWAY. We order it from Amazon .... can't find it here. Sometimes it's a spray, sometimes a foam. Both atre the same. It is such a sad situation........we've had friends say, "put her down !" Well, that's not happening altho we did consider it, I'm ashamed to say. Now we have limited her access to lots of areas of the house, but that means it looks like a mess all the time. I can tell you cats DO NOT LIKE to walk on plastic grocery bags, or any kind of foil, or other "funny" things. Very fussy. That can work in your favor ! I sit here looking at my kitchen stool on a little rug that is now covered with plastic bags ! Too easy for ME to slip on, so temporary. I sympathize with your problem. I hope you can find something that works. It's the cat problem no one talks about, so thanks!

What about trying vinegar on the area, using enough to soak into the pad. After this sits for a time, put a white cloth over the area and step on it to remove some of the liquid to speed drying. Put a fan to blow on it also. Next, make a solution of water and baking soda and pour onto the area, letting it soak into the padding. Don't over wet so you don't ruin the subfloor or cause mold. After the baking soda has dried, vacuum to remove the residue on the carpet. If this has helped you might need to repeat. Hope this helps. Cat urine is a bad smell and our cats can be moody.

Hhertenstein, I truly hate being the bearer of bad news, but yes, I do believe you are going to need a new pad and carpeting .. sighhhh... and probably also special treatment for the flooring UNDER the padding, as I am sure it, too, has absorbed some of the urine and odor :( HOWEVER BEFORE YOU RIP UP THE PAD AND CARPET why not try one more thing, what would it hurt?

Supposedly THIS wman has or has had 16 cats, so who would know better than she? (By the way, did you know that you can use a black light to locate the stained area so you will know exactly where to treat? YES! Leave it to an old hippie to know about that LOL)

And if all else fails because the urine HAS soaked deeply into the wood, unfortunately you will probably have to sand the flooring down enough to remove the stain and then reseal it:

Good Luck Hh, and thank you for coming to HOMETALK for answers :)

All great suggestions here! I have 6 rescue cats and feel your pain. I use vinegar, but I am on a slab and my carpet is old and will need to be replaced. Regardless of the extra work and / or money, I could never put an animal down unless it was sick, in pain and no other option would restore their quality of life. Give these suggestions a try before ripping up and replacing part of your carpet.
