One of my cats has been using the downstairs bedroom carpet as her own personal latrine the last couple of days. She is now a barn cat. So here's the question: How do I get the smell out? Does the Nature's Miracle stuff I see at the pet store really work? The stuff seems expensive, but if it does work I'll buy it. I got in there with some distilled vinegar and it got the stain out, but it still smells like cat pee. Help!
