I hope the smell is gone!! What really works on cat urine is a product called Nature's Miracle. It works by enzyme action not just a fragrance cover up. You saturate the areas where the urine is and let it air dry. I had to use this on my new furniture when my cat sprayed on it. It sure does work!!!
The big thing with pet odors is that we may not be able to smell it but our pet can---so the odor must be ALL gone or they will go back to that same spot again.
Best wishes, Chris
