Performance notes
The Ammonia Block technology is aimed specifically at neutralizing ammonia odor, which tends to be the sharpest smell in a multi-cat litter box, while the light weight clumping formula is designed to reduce the physical effort of pouring and carrying compared to denser clay litters. The two-box 37 lb total supply is built for households managing more than one cat's waste output.
