Clumping litters form tight, hard clumps that make scooping urine and solids easier for spot removal. Non-clumping options (crystal/silica, pine/wood) focus on absorption; they typically rely on stirring or scooping solids and require periodic full refreshes rather than forming removable clumps.
Listings show a range of stated control or replacement intervals, roughly from about 10 days up to 30 days. Some silica/crystal options and a few clumping formulas mention intervals around two weeks to a month.
Listings include both scented formulas and unscented/fragrance-free options. Some products also note odor-control additives such as baking soda or activated charcoal.
Package weights in these listings range from about 8 to 38 pounds, with many products shown around 20 pounds.
Listings describe a mix of technologies and additives: ammonia-blocking or branded "freshness" technologies, absorbent crystals that eliminate moisture, and neutralizing additives such as activated charcoal or baking soda.
