Review on SCENT AWAY Fragrance-Free Cat Deodorizer with Active Carbon - Effective Cat Box Odor Eliminator and Litter Box Deodorizer by Ashley Stewart

I have four cats and 2 toilet robots. Because robotic scavengers remove clumps and solids as they appear, the smell is rarely present anyway. Sometimes when the robot has a seizure and doesn't turn around immediately, I can detect a slight odor. After using it I didn't feel any difference. If feces or urine lingered a few minutes longer, I could still smell it. Maybe my nose is too sensitive. It seems to have worked for others. But I won't buy this again.
