Direct answer: a widely used starting point is one litter tray per cat, plus one extra—so three trays for two cats. Place them in separate locations; three trays side by side can function like one guarded resource.
Spread trays around the home
Choose quiet, accessible spots with more than one practical route where possible. Avoid forcing a cat past another cat, a noisy appliance or a busy doorway to reach every tray.
Match each tray to the cat
A large cat needs room to enter, turn and dig comfortably. Offer different tray styles if preferences are unclear, and do not assume that an automatic tray removes the need for alternatives.
Watch use and adjust
Soiling outside the tray, waiting, guarding or one cat consistently avoiding an area can signal a layout or health problem. Clean appropriately and ask a vet about sudden toileting changes.
