Our home was brand new when we bought it in 2014. In the process of taking out the carpet to put down LVP, my cat had peed on a corner of our livingroom. It was pretty soaked in an area of 12" long and 3" deep and looked like he had been doing for a long time. We are in the process of deodorizing and drying it. So far it seems to be structurally sound. If i choose not to replace the subfloor, my question is, even after deodorizing, drying. and sanding, will the dried urine in the wood continue to deteriorate the subfloor? Again, i am okay NOT replacing the subfloor if it won't continue to breakdown the wood. situation with the cat has been taking care of and so far it smells like we have rid of the smell. we plan to wait for an answer before we move forward installing the floor.. thank you
