There are several specialty products to completely clean stains from cats. These products are often over-priced as they are gear specifically to focus on cat urine. But, anyone who has tried these items know they don't work. Often times, they may be watered down, soapy, or higher scented. I can not show you the number of products I used before I finally found one that worked. Some would get rid of the stain, until it absolutely was dry and I just realized the stain wasn't gone, it had been just watered down. Some would remove the smell, but only by masking it which has a pine or citrus smell. Once that masking smell faded, the urine smell would be in the same way strong since the day it was discovered. Today's building codes state spaces using furnaces will need to have means for getting together again combustion air as it used. Newer homes have ducting installed, during construction, thats liable to bring oxygen on the surface to a area close to the furnace. This ducting, usually called constitute air duct, or combustion make-up air, is sized according to the capacity in the furnace.
