Terrific surprise!
We moved into a new home. Our cats' litter box used to be downstairs. Never noticed a smell from it as it was cleaned daily. Now their box is in our laundry room where we pass by often. Seemed like the smell of the litter, not urine, was quite noticeable, unlike before even though it's cleaned twice a day now. Didn't know what to do about it. Read about this device and I bought 2, one for inside the room and one for outside as you enter from the garage and pass by. Within an hour it seemed much better and within 2 hours the smell was no longer noticeable at all. I can't believe they worked so well. Very very happy with this item!!!
