I live in a small apartment, and Dr. Elsey’s litter has been the least offensive smell-wise. The ultra premium clumping cat litter locks things in better than anything else I’ve tried. I scoop daily, and the box never gets that ammonia hit. It’s not dust-free, but it’s manageable. I’d rather deal with a little tracking than constant odor. Pairing it with wet food like Pure Cravings also helps keep smells down.
