Overview
Scooping tight clumps from a multi-cat litter box is the job this clumping litter is built for. Ammonia Block technology and Febreze freshness handle odor, and a low-dust, low-tracking formula limits mess.
Tight clumps and an ammonia-control feature target the main multi-cat complaints, and compatibility with most automatic boxes widens where it can be used. The limitation is scent: it is fragranced with Mountain Spring, and the material is listed only as fiber.
Who it's for
A multi-cat home using standard or automatic litter boxes that wants a bulk pack with odor control. Households that prefer unscented litter, or cats that dislike fragrance, should choose an unscented product.
Pros and cons
- Forms tight clumps
- Ammonia Block technology

Performance notes
Clumping happens as the litter binds around liquid, so tight clumps scoop out cleanly and leave loose litter behind. Ammonia Block technology and the scent address odor, and low dust reduces airborne powder. The highlights note compatibility with most automatic boxes.
