Key Features

1. Superior clumping performance

Fast absorption & Quick hard clumpping

Our Wyoming bentonite formula delivers exceptional clumping strength that holds together during scooping, making cleanup effortless for cat owners. The uniform granule size(0.5-2.0mm) ensures consistent performance every time.

2. Advanced dust control technology

Proprietary CAT system

Our exclusive Clear Air Turbulence(CAT) system is a proprietary dust removal method that makes our cat litter products cleaner and safer. This final dedusting process eliminates airborne particles, protecting both cats and their owners from respiratory irritation.

3. Non-stick formula

Won't stick to litter box

Advanced formulation prevents the litter from adhering to the litter box surface, making cleaning easier and extending the life of litter boxes. This feature is highly valued by cat owners and reduces replacement costs.

Long-lasting freshness

Superior deodorizing performance keeps homes fresh longer, reducing the frequency of complete litter changes. Our natural sodium bentonite provides excellent odor absorption without artificial fragrances.
