I use Nature's Miracle and it is wonderful. I've used it for years! It cleans up pee/poo spots as well as vomit. And, since it has enzymes in it all smell has disappeared and my animals (I have 5) have not had accidents in the same spot again. I love it. Sometimes if it's really bad (like diarrhea) I have had to go over the spot a couple of times to get out the stain but in the end it does work.
