There is one spot in my dining room in front of my patio door that I keep their potty pad. The potty pads have leaked so much that I believe that the pee has actually went into the cracks of the hard wood. In the morning when the sun comes throught the door and shines on the floor in that area it smells like pee....
. I am not sure what to do about it, I don't know if it will eventually go away or if I need to replace the wood in that area. I have since gotten a pee pad holder and that helps the leaking.
