Strengths and trade-offs
Drawn from this product's published specifications.
- Unscented formula with no added dyes or fragrances
- Ammonia block technology targets odor at the source
- Low dust, formulated for multi cat households
- No fragrance means it relies entirely on ammonia control for odor
- 18.5 lb box is heavy to lift and pour
Performance notes
Ammonia block technology targets the specific odor compound ammonia rather than relying on a general fragrance to cover smells, and the formula is low dust, which matters most in multi cat boxes that see frequent scooping.
