- One-sentence answer
- Use one litter box per cat, plus one extra; spread them out so each cat has an easy, stress-free option.
- Possible reasons
- Cats prefer clean, available toilets; extra boxes reduce wait times and smell buildup.
- Multi-cat households need separation to lower guarding and ambush risk.
- Some cats split duties: one box for pee, another for poop.
- Health or mobility issues make long walks or stairs a barrier.
- Apartment layouts can create “dead zones” where a single box is hard to reach.
- Observations and simple non-medical tweaks Keep a 10–14 day log: time of use, which box, misses or hesitation, digging time, and any meowing or pacing. Note clump size (rough gauge of urine output), stool consistency, and any accidents—where, when, and what just happened (loud noise, guest arrival, closed door).
Daily rhythm: scoop at least twice daily; top up litter to 5–7 cm depth. Full refresh and wash weekly (unscented soap, warm water), especially for clumping clay or plant-based litters. For two cats, consider a midweek partial refresh.
Placement plan: distribute boxes on different sides of the home and on each floor if multi-level. Avoid line-of-sight traps—don’t cluster boxes together or hide all in one room. Keep at least one box away from washers, loud HVAC, or busy hallways. Provide clear entry/exit; uncovered boxes are often better tolerated.
Size and access: most cats prefer large, open boxes—aim for a tray as long as the cat from nose to base of tail. For seniors or arthritic cats, use low-entry fronts (5–7 cm). High-sided boxes help litter kickers; place a mat to catch scatter.
Attention and reinforcement: if a cat uses a box after previously missing, quietly praise and offer a tiny treat near (not in) the box. Never scold for accidents; clean with enzymatic cleaner and block access to the soiled spot for a few days.
Stability check: with correct count and placement, accidents should drop within 3–7 days and remain low for 10–14 days. If a cat queues or avoids certain boxes, adjust location, size, or litter type—trial one change at a time for 5–7 days.
- When to consult a veterinarian or behavior professional
- Sudden accidents, straining, frequent tiny pees, blood-tinged urine, or vocal pain.
- Persistent avoidance despite added boxes, scooping, and quieter locations.
- Multi-cat tension: guarding, ambush near boxes, or escalated hissing.
- Senior cats missing the box alongside stiffness or difficulty stepping in.
