Zero Odor Litter Odor Eliminator - Air Cleaner, Purifier & Deodorizer - More Than an Air Freshener - Actually Eliminates Odors at a Molecular Level - Refill (64 Ounces)

I use this in conjunction with Rocco and Roxie deodorizing pellets (this has a stronger scent, warning if you're sensitive). I spritz once or twice every time I clean, you really don't need a lot. There is no covering up the immediate post-poop odour (I don't think this is possible lol) but it has essentially eliminated litter-related smells otherwise. This bottle and the spray bottle lasted me nearly two years, definitely worth the investment.

Excellent product! I have 3 cats using a very large litter box. Two or 3 sprays daily keeps the odor from becoming an issue. So much better than the powdered brands! I've used everything and this works better than any other product I've used.

I initially ordered the smaller spray bottle which I used up pretty quickly so I ordered the refill bottle. I use it sparingly now because it's expensive...but as long as it works thats what matters. It totally got rid of the underlying urine smell.

Works very well

We don't have a large living space, so the cat litter boxes are not able to be tucked away, and sometimes the smell can be very noticeable. With two or three squirts of this spray, the smell is much less obvious. It's great that you can buy a large bottle and refill the smaller spray bottle.
