It really works!
I rarely write reviews but was shocked by how well this works.  We have 2 cats, 3 litter boxes in a small room that is connected to another room in our basement.  We typically clean the litter boxes weekly and by mid week I could smell it when I walked into the connecting room and sometimes even the basement.  Now when I walk into the room with the litter boxes there is ZERO smell....nothing.  It's crazy.  So happy with this purchase!
