Overview
Fresh Step's Advanced Odor Shield clumping litter in the Multi Cat scent, sold as two 18.5 lb cartons totaling 37 lbs. It's a clay-based, lightweight clumping formula built around what Fresh Step calls Ammonia Block Technology, with Febreze freshness layered in.
This listing is the Multi Cat scent version; a companion listing in the same lineup swaps in a Gain Original scent instead, with the same clumping clay formula in the same 37 lb two-carton size. The lightweight branding refers to Fresh Step's reduced-density clay, meant to cut down on total bag weight without changing litter box coverage.
- 37 lbs total across two 18.5 lb cartons
- Ammonia Block Technology for odor control
- Febreze freshness layered into the Multi Cat scent
- Lightweight clumping clay formula
Who it's for
Multi-cat households wanting a scented clumping clay litter in bulk, delivered as two cartons rather than one large bag.
Pros and cons
- Two cartons are easier to carry than one bag
- Ammonia Block Technology targets a common multi-cat odor problem
- Lightweight clay formula reduces the total carried weight
- Clumps for standard scoop cleaning
- Scented, not suited to fragrance-sensitive households
- Clay litter tracks and produces dust
Performance notes
The clumping clay forms solid clumps for scooping, and the Ammonia Block Technology targets ammonia odor specifically, which tends to build up fastest in multi-cat litter boxes. Febreze freshness is layered on top as an added scent component.
