Review on Zero Odor – Litter Odor Eliminator: Permanently Eliminate Litter Odors Using the Best Patented Molecular Technology - Pet Safe & Works on all Types of Litter, 16oz (Over 400 Sprays) by Christina Suk

This stuff REALLY works! In winter we had to bring a tray for 2 cats. The vet recommended this product. The room smelled like a garbage can even though it was washed every day. When we first started using Zero Odor toilet spray, you couldn't even tell the box was in the room. We picked up the box, put the litter on one side, sprayed the box and opened the litter, moved the litter to the other side, repeated and then sprayed again and smoothed the litter. We now have small bottles of regular Zero Odor in every room for other household fragrances. It's amazing how well this works.
