Need to oust pet urine scent under carpet
We are getting new carpeting installed to replace carpet that's been in our house probably through two previous families. Someone must have had an animal (chew marks seen on windowsill) because our cat walked into a room I use for ironing and urinated in several areas and then defecated in another. Since then, we've kept the door to that room closed but she also urinated just outside the door right after that so we put a plastic mat over the area. So...what can I do when the installers rip up the old carpeting in that area? At the carpet store someone mentioned a product called Kilz but when I looked it up it says it's a sealant and paint. Thanks!
