System Litter Granule Sizing to Prevent Clogging and Rejection

The patent applies parameter changes by precisely controlling the granule size parameters of the litter. Specifically, it sets the granule diameter to 6.0 mm or less while limiting the proportion of granules with any smaller dimension below 3.2 mm to 6% or less. This parameter optimization resolves the contradiction by finding the optimal size range that prevents clogging in 2.3-2.7 mm hole parts while maintaining cat acceptance through sand-like texture.

The patent resolves this contradiction through parameter changes by establishing specific granule size thresholds. The granule diameter is controlled at 6.0 mm or less to provide sand-like comfort for cats, while the minimum dimension is maintained at 3.2 mm or above for 94% or more of granules to prevent fitting into 2.3-2.7 mm hole parts. This dual parameter control simultaneously achieves cat acceptance and clogging prevention.

The patent applies parameter changes to prevent litter from falling through hole parts while maintaining cat comfort. By controlling the granule size such that 94% or more of granules have any smaller dimension of 3.2 mm or more, the litter granules are ensured to be larger than the 2.3-2.7 mm hole openings, thus preventing passage through holes and retaining litter functionality while preserving sand-like texture for cat acceptance.
