If you decide to replace your flooring, I highly discourage you from getting wood! I had a female cat who would constantly pee in one corner of my room. Yuck! Well, the urine seeped into the wood and into the concrete underneath.
I am going to have it ripped up and replaced with ceramic tile because it is non-porous. BTW, the kitty disappeared eventually. I loved her, but hated her bad habits which I tried everything to break with no success.
