Arm & Hammer Multi-Cat Clumping Litter Unscented, 26.3lb

TLDR Review: Arm & Hammer Multi-Cat Litter

Published: December 24th, 2025

Pros

  • Excellent odor control thanks to the baking soda formula, which is especially appreciated for sensitive noses.
  • Low dust formula helps reduce mess and airborne irritants around the litter box.
  • Unscented option eliminates strong chemical or unpleasant odors common in other litters.
  • Clumps well enough to make scooping and cleaning manageable when the quality batch is used.
  • Cats tend to be comfortable with this litter and use it consistently without issue.
  • Works effectively for multat households, especially when the litter box is cleaned regularly.
  • Lightweight to pour despite the large 26.3 lb bag, making handling easier.
  • Mixing with natural wood pulp or corased litters can enhance overall performance.
  • Trusted brand with responsive customer service that has addressed dissatisfaction with coupons.

Cons

  • Clumping performance is inconsistent, with some batches crumbling rather than forming solid clumps.
  • Onlinurchased bags reportedly have poorer quality and more gravel-like texture versus the sandy, better-clumping versions from physical stores.
  • Texture can feel rougher and less pleasant to some cats, potentially affecting usability.
  • Heavier product to carry, making delivery or transport considerations important.
  • Requires frequent litter changes (every other day) to maintain odor control effectiveness.
  • Some users experienced quality variability, which may cause frustration if purchased online.
  • Not the strongest clumper on the market compared to competing litters.

Bottom Line

Arm & Hammer Multi-Cat Clumping Litter Unscented delivers strong odor control and low dust benefits, making it a solid choice for multi-cat homes with sensitive noses. However, its clumping consistency varies, especially between online and in-store purchases, so buying from a trusted local retailer may be your safest bet. If superior clumping is a dealbreaker, consider trying alternative brands that specialize in firmer clumps, but you’ll miss out on the excellent odor control and low dust that this formula offers.
