Hi Kaz,
White Vinegar is very good at getting rid of cat pee niffs... it breaks down the bacteria.
Saturate the area with a 50/50 water/white vinegar solution and allow it to air dry (use a fan if you're in a rush).
Cover the area liberally with baking soda � use lots!
Fill a container with enough water to saturate the stained area and add a drop of regular dish detergent. Pour the solution on top of the baking soda.
Using either your hands, towels, or a scub brush, work the baking soda/water/detergent paste into the fabric � work it in good and deep, then allow it to air dry.
Once the area has dried completely and the baking soda has returned to powder form, vacuum it up.
If the vacuum isn't cutting it, it can be blotted up using water and towels.
Repeat steps 3-6 as needed to remove any remaining odor.
It does work!!! :D
