My senior cat has kidney problems and food intolerances, so vomit happens. I used to use vinegar to clean up her messes, but now I live in a house with a pretty nice wood floor that I have no idea how to take care of. But I heard that vinegar is harsh on wood. So what should I clean up the vomit spots with that won't mess up the finish on the floor? Or won't mess it up any more than the vomit, anyway.
