Help!!! Original hardwood floor in our old home. I had no idea that our cat was peeing in this fabric storage thing until I caught her today and it seeped through and left this on the floor. Apparently she’s been doing it for awhile and I didn’t know. We always have an air purifier going in this room. (She’s old so no getting rid of her is not an option, I won’t do that to her.) Is there anything I can do to get the original color back? 
currently trying white vinegar and warm water
