Cat Litter and Litter Trays

Cat litters and trays ranked on odor control, clumping, dust, and tracking.

The best kitty litter is the one your cat will use happily and you can live with daily. Clumping clay is the default for a reason: it forms firm, scoopable clumps, controls odor well, and most cats accept its sand-like texture. Crystal litter made from silica gel absorbs urine instead of clumping it, so it lasts longer between full changes and tracks less, while plant-based options such as corn and wood fiber are lighter, lower in dust, and often flushable or compostable where local rules allow.

Odor control, dust, and tracking decide day-to-day satisfaction more than brand names do. Scented formulas mask smells for people but can push scent-sensitive cats away, so unscented litters with clay, charcoal, or baking soda are the safer start. Tray sizing matters just as much in multi-cat homes: the standard rule is one tray per cat plus one extra, each tray should be about one and a half times your cat's length, and two cats sharing undersized or too few trays is the most common reason for messes outside the box.
