DEPT-05 · CLUMPING SODIUM BENTONITE & BIO-ENZYMATIC CLEANERS

Cat Litter & Odor Control

99.9% dust-free sodium bentonite litters, activated charcoal ammonia blockers, and CRI-certified bio-enzymatic urine destroyers.

Multi-cat litter boxes fail when porous clay crumbles during scooping, leaving ammonia-soaked granules behind. We test high-swelling sodium bentonite litters, non-stick coated granules, and bacterial protease/uricase enzyme sprays across automatic and standard pans.

Department Evaluation Protocols:

Clump Drop-Impact Cohesion (15- minute urine clump drop from 30 cm onto 12 mm sifter grid)

Headspace Ammonia Suppression (PPM NH3 concentration at 72 hours in multi-cat simulation)

Airborne Particulate Dust Index (Laser nephelometer PM10 dust measurement during 1-meter pour)

Uric Acid Crystal Digestion (Bio-enzymatic spore reactivation and UV blacklight stain elimination)
