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 Paul Massey

It takes about 3-5 trigger pulls to get a spray every time. The product itself works very well.** But the first spray is important because it's about fighting bad breath (not just that I'm an impatient New Yorker, haha). I bought 3 bottles and each has the same problem so it's not like I just screwed up. If you have an earlier type of atomizer (a few years ago) it will work great. They changed the shape of the bottle and atomizer. Luckily I'm still old. ** Works on poop. I can't confirm urine. Please check other reviews.
