Cat urine is mighty powerful stuff. It soaks into materials, like wood, concrete, etc. So what you may need to do is pull up the carpeting, clean the concrete, let that dry then paint the concrete with a few coats of concrete epoxy. Also known as garage floor paint. However for your needs you would NOT use the sand. The idea here is to seal up the spot, preventing the stench of old urine to permeate up through the carpet into the room. The best cleaning, prior to painting, would be to use bleach water, letting that soak in, followed by a few plain water rinses, then let it dry over night then paint it making certain to extend the paint at least 3 feet beyond the urine spot. Carpeting will clean with steam cleaning and urine be-gone - a product sold at pet stores to deal with pet smells in fabrics.

sprinkle baking soda over it. Rub the baking soda into the soiled area and let dry. Brush or vacuum to remove the dry material. 2. Another option is the white vinegar. Mix together 1 quart warm water and 1/2 cup white vinegar, and dribble the mixture onto stain. Place dry towels over the stained area and put something heavy over the towels to increase the pressure. After some hours remove the towels and raise the nap of the carpet with a soft-bristled hairbrush. Note: Test the vinegar solution on a piece of fabric that is hidden from view - under the cushion or on the backside of the furniture. 3. To clean old or heavy stains in carpeting, consider renting an extractor or wet-vac from a local hardware store. The extracting/wet-vac machines works like a vacuum cleaner and do the best job of forcing clean water through your carpet and then forcing the dirty water back out again. When you use these machines, you should follow the instructions carefully. Note: Don’t use any chemicals with these machines – they work much more effectively with plain water. 4.Another way for cleaning the cat urine from carpets was submitted from one of our visitors - Elaine Byrnes. She says that if you add a several drops of Listerine mouthwash to the water/perioxide mixture it helps a lot with the odor. In addition to a great cleaning solution, this is a safe pest spray for plants that are in and around children or pets. 5. One of the newest technologies for clean cat urine is penetrate the soiled area and deactivate the odor with peroxide or detergents. Simply spray a product that consist a 3% hydrogen peroxide and wait about five minutes. After that use a clean white absorbent cloth, blot the area, pressing down firmly (do not rub) for 30 seconds. Repeat this blotting process until the area is dry. If the stain or odor persists, repeat the process. Once the soiled area is really clean, you should use a high-quality pet odor neutralizer available at pet supply stores. Test the affected surface for staining first, and read and follow the instructions. If the area still looks stained after it’s completely dry from extracting and neutralizing, apply a specialized stain and odor removing bacteria/enzyme cleaner, such as "Outright Pet Stain Eliminator," "Pet 'Oops' Remover," or "Stain Gobbler".

Sadly, there is not one item out there that will get rid of cat urine. There are plenty that promise to, and there are some that can mask the odor, but the only true way to get rid of cat urine is to replace the carpet. It doesn't matter if there is or isn't a pad underneath.
