Quick verdict: start with unscented clumping clay — Dr. Elsey's Ultra for most cats, or Fresh Step Advanced Simply Unscented when odor is the main fight without perfume. Choose plant, pine, or crystal only when you want lighter bags or a different cleaning style.

Dust and “odor day” figures on retail listings are manufacturer claims, not independent lab results.
Our default first pick for most cats: unscented bentonite clay that hard-clumps so you scoop daily instead of dumping the whole box. Cornell, the ASPCA, and the AAFP all note that most cats prefer fine-grained, unscented clumping litter about 1–2 inches deep — this matches that profile.
Strong runner-up when odor is the pain point but you still want unscented clay. Activated charcoal is the listing’s odor story — not the same as fragrance — and the bag is lighter than a 40 lb clay sack.
Only pick this first if your cat already tolerates scent. Cornell/ASPCA/AAFP say most cats prefer unscented litter — so Platinum is a situational choice, not our default. Baking soda + sealing claims target odor; listing notes robotic-box use.
Solid plant-based clumping option made from whole-kernel corn. Lighter than clay to pour; listing warns not to mix with non-clumping litter. Still bag solids and trash them — do not flush.
Wheat clumping litter with natural-enzyme odor positioning and no added perfume. Heavier bag than some plant options but still a clay alternative for households avoiding bentonite.
Light tofu-style litter with larger granules pidan says resist dusting and tracking. Pour deeper than clay (pidan often suggests ~2–3 inches) so clumps hold. Soft clumps can form with heavy urine — scoop promptly. Do not flush despite flushable marketing.
Non-clumping pine: scoop solids, stir/absorb liquids, replace the box on a schedule instead of carving out urine clumps. Great when you dislike clay dust/weight — poor fit if you insist on hard urine clumps.
Silica crystals absorb urine in place; scoop solids only. PrettyLitter markets color changes tied to urine pH/blood. Important: color change ≠ diagnosis, and a “normal” color is not a clean bill of health. Confirm anything worrying with a veterinarian.
For most cats we start with unscented clumping clay such as Dr. Elsey's Ultra. It matches what Cornell/ASPCA/AAFP describe as typical preferences.
Clay hard-clumps and is familiar; tofu/plant is lighter; crystal/pine usually do not clump and need a different cleaning routine.
About 1–2 inches for most clumping litters (Cornell/ASPCA). Some tofu brands recommend deeper beds so clumps hold.
