OdorLock Unscented is a clumping clay litter made in the USA from Wyoming clay, sold in a 25 lb box. Its draw is odor control without fragrance: the brand says its technology blocks ammonia formation and holds odor down for up to 40 days, and that it lasts about 40% longer than a popular clumping brand. It forms small, hard clumps and is billed as 99% dust-free with low tracking, which suits multi-cat homes and people who dislike perfumed litter. Against scented premium clays it competes on odor blocking rather than smell masking, and owners rate it highly for keeping the box neutral.
