Odor Ban from Sam's Club is supposed to work well, but I have never tried it.  I hope it is carpet that is the problem and not hard wood floors or even the walls, because they will all have to be removed most likely and then treat the cement.  Sorry, Terrible Problem!

Remove the carpet and sub-flooring. Make sure you go under the house if it is on a crawl space and remove about 3 inches of the top layer of sand. Unless, of course, you just want to hide the smell and fool the buyers. And then I know a few people who will give you that advise, too.

Jennifer is right for a normal light problem. If it has been a long term problem the Gregory is correct, the subflooring is more than likely damaged and needs to be replaced. Cat especially pee in the same place everytime and can even cause dryrot after a while. When remodeleing a home! That is one of the worst problems, worse than smoke!

As an owner of 2 senior cats who have on occasion forgotten where the potty is....I use OdoBan spray I picked up from Walmart for $2.00.

I did buy a wonderful odor eliminator at a cat show once....you can find all kinds of remedies from cat people...check online.

"Nature's Miracle", gets at the enzymes - which is the cause of the odor, probably need to apply to the subflooring.

I've heard some good reviews from fellow agent and clients who've used it.

Availbale in most pet stores.

I have used Ozone generators or blasters in the past to eliminate all oders from a home. You can rent them for around $50 for 3-4 days or purchase them.

Hi Jody - I've tried all of those chemicals over the years, if the padding is saturated, nothing works.  Carpet needs to be taken up and the subflooring can be sealed with a coat or 2 of KILZ sealing paint. Replaced if rotted under there in spots. Then the new flooring put over it and the smell will not return.  Watch the baseboards too.  Sometimes the smell can be in the wood of baseboards as well as drywall - KILZ works well for that too.  A lot of work, but the return on the investment for the seller will be good. Nothing seems to bring a low ball offer more than pet odors from my experience - especially cat smell. And make sure the cat stays outside after and does not reinvent the problem.  I love pets, but boy they can really cost people far more than just the food and pet bills when it comes to their homes. Best wishes.

I love Greg's answer, he just cuts to the chase. Probably the best cure too.

If it is not your house ask the owner to hire a cleaning crew.  If you need feedback to get the owner to act.

Jody,  Your listing that my client viewed yesterday is a very nice property but it smells really bad.  Unfortunately we did not get to view all parts of the home, because it smelled so bad that we had to run out of there gasping for air.

Thank you and the entire staff at Gas Mask Realty for making this property available.
