Cats that spend time outdoors tend to be picky about where they go: a box that smells strongly of perfume, or litter that sticks to paws and trails indoors, gets avoided. For an outdoor area, the quiet qualities — unscented formulas, low tracking, low dust — often matter more than the loudest odor claim.
That is how the table below is organized: two unscented options, two scented multi-cat formulas with 14-day odor control, and one charcoal option in between. Start with the row that matches your cat’s tolerance for scent, then read the detail.

The scent split is the simplest way to choose: the two unscented entries and the charcoal option suit cats that shy away from perfume, while the two Arm & Hammer entries suit owners who want the longest stated odor window and are comfortable with a scented formula.
Tracking is the second split — the Platinum formula and the low-dust options keep more litter in the area, which matters most when the box sits near a door the cat walks through.
