If I could give Naturewise Chem-Dry a ten-star rating, I would! We have cats, and they have had some issues with not using the litter box, and Naturwise has been able to get the cat mess out without using chemicals. They have shown up at different times at a moment's notice. We were remodeling when we were taking up the carpet we noticed that the cat mess had gotten down to the subfloor. They came out that day! They are always very professional, friendly and always take the time for us. We appreciate how fantastic they are.
