Natures Mircle is good stuff what it does after cleaning is eliminate the "odor" of the "spot" where he went. If you didn't use something like that he would always go back to "that spot" or around and eliminate.

Also another good investment is carpet cleaner/scrubber. Our little furry guys/gals do make their messes. Tinted food (stains carpet), hairball messes leaves stains and when they jump around and tip over glasses of mom's soda that makes a giant mess. .
