Waste bin capacity determines how often you need to empty the automatic litter box. In the catalogue analysed for this site, the largest bin size is both the best represented and the best rated, while the smaller tiers still hold a solid satisfaction level of their own. A multi cat household generally benefits most from a larger bin, while a single cat owner with limited storage space can comfortably go with a smaller one.
