My ferrets have been having a lot of "accidents on the carpet" but thankfully I found a cleaner that really gets rid of the odor and any stain. It's also easy and inexpensive. The OxiClean crystals are what I use, just pour some hot water in a bottle add a 1/4 scoop of the oxi crystals, shake then spray or drizzle the mixture over the spot where they went. Wait a couple of minutes then rub the area with a wet cloth. Very simple! Only problem is you have to mix it as you need it, the mixture doesn't stay effective as the oxidizing part finishes.
