I have discovered a spot in my family room that someone has begun using as a toilet. I don't know how long, but I can smell it when I get down close, but now far away, so I assume not very long. How do I get the smell out so the cats cannot smell it anymore? I am setting up the video camera as we speak to catch who it is. I'd actually like to catch who did it before I clean it thoroughly. Anyone have any favorite home remedies for cat pee? or particular products that work. I actualy already dumped an entire gallon of Simple Solution on it and let it sit overnight, but I can still smell it slightly if I stick my nose in the carpet
