Arm & Hammer’s two multi-cat clumping litters earned the same 4.3/5 rating in Cats.com’s 2025 review, but they differ most in cleanup: Multi-Cat Slide was reported to release easily from the box, while Clump & Seal was praised for hard clumps and odor control. Both had some scent and occasional clump breakage, so neither is a universal fit.
What the Cats.com review tested
In a review last updated September 19, 2025, Cats.com author Kate Barrington says the site purchased three Arm & Hammer products and tested them for several weeks on several cats. The review says the products were not provided in exchange for a favorable review. These are the reviewer’s reported observations, not a controlled comparison or veterinary assessment.

How the two multi-cat litters compare
| Product | Cats.com rating | Reported strengths | Reported drawbacks |
|---|---|---|---|
| Arm & Hammer Clump & Seal Multi-Cat Formula | 4.3/5 | Hard clumps, odor control, and low dust and tracking | Slight scent, sandy texture that some cats may dislike, and some clumps breaking apart during scooping |
| Arm & Hammer Multi-Cat Slide Easy Clean-Up Formula | 4.3/5 | Released easily from the litter box, clumped well, and had low dust and tracking | Sandy texture, occasional broken clumps, and slight scent |
Cats.com reports that both formulas claim seven-day odor protection; that is a product claim noted by the review, not an independently verified result. Barrington’s overall assessment was that the products largely delivered on long-lasting odor control, hard-clumping action, and low dust and tracking.

Which formula may suit your household?
Choose Clump & Seal if firm clumps are your priority
The review’s observations make Clump & Seal a reasonable option to consider if you want hard clumps and odor control. Some clumps reportedly broke apart during scooping, however, so the experience may not be consistently mess-free.
Choose Slide if litter sticking to the box is your main frustration
Slide’s distinguishing reported advantage was that it released easily from the litter box. It also clumped well, though occasional clump breakage was noted. The review gave it the same rating as Clump & Seal; it does not establish that one is better for every cat or household.

Both formulas were described as slightly scented and sandy in texture. If your cat avoids scented or granular litter, those observations are worth weighing before switching. Cats.com does not report that every cat in its test reacted the same way.
What about the deodorizer powder?
Cats.com rated Arm & Hammer Cat Litter Deodorizer Powder 3.75/5. The reviewer found that it controlled odor strongly, but also noted a heavy scent and added dust. The review cautions that deodorizer is not a replacement for regular scooping.

Verdict
Based on the Cats.com review, both multi-cat formulas are worth considering if you want clumping litter with reported odor control and low dust and tracking. Let cleanup needs guide the choice: Clump & Seal was noted for hard clumps, while Slide was noted for releasing easily from the box. Their shared drawbacks—slight scent, sandy texture, and occasional broken clumps—may matter more for cats sensitive to those qualities. The deodorizer powder may help with odor, but its heavy scent and added dust make it less appealing if those are concerns.
