Litter Zero Refill
Live fresh, Live odorless
Ultimate odor control
The waste bin uses a multi-layer refill bag with an odor-locking barrier that keeps smells trapped inside.
One refill lasts up to 2 months for one cat.
Easy to replace!
Take off the cartridge cover, pull out the liner, pop the cartridge into LitterZero—and that’s it!
Done! Super simple
EVOH
Advanced Functional Plastic
Engineered barrier-plastic blocks out gases like oxygen and nitrogen, just like in food and medical packaging. With LitterZero, the same premium protection prevents odor from leeching out of your bin.
7-layer
The self-developed 7-layer LitterZero refill liner provides outstanding odor-blocking performance with its superior thickness. Designed through extensive testing and research, it features Petsnology’s proprietary 7-layer ratio for complete odor control.

A. It’s simple, just place LitterZero next to your litter box and scoop waste directly into it.
A. The included scoop is specially designed to fit perfectly with LitterZero’s opening, with three different hole sizes for precise scooping. But if you already have a scoop you prefer, you can continue to use it.
