Questions, answered
How often should multi-cat trays be scooped?
At least once a day, and twice is better with two or more cats sharing trays. Odor and avoidance problems usually trace back to scooping frequency before litter choice.
Scented or unscented for multiple cats?
Start unscented if any cat is picky. Scented multi-cat formulas mask odor for people, but a cat that dislikes the smell will find somewhere else to go.
How much litter do multi-cat homes use?
Plan on a full tray change more often than single-cat homes and keep about 3 to 4 inches of litter depth so clumps form without sticking to the bottom.
Can two cats share one big tray?
Some bonded pairs do, but the safer setup is multiple trays in different places. Resource guarding around a single tray is a common hidden cause of accidents.
