I’ve used Arm & Hammer multi-cat litter in a three-cat household, and it holds up surprisingly well. Odor control doesn’t collapse under heavy use, which is huge. Clumps stay intact even with frequent trips to the box. Tracking happens, but that’s expected with clay. Feeding a mix of Nutra Nuggets and Kirkland Signature, I really rely on strong litter performance, and this one hasn’t let me down.
