How many litter boxes does a cat need?
Start with one litter box per cat plus one extra, then spread them across separate, quiet locations. Several trays in one row do not give a blocked or worried cat a genuine alternative.

✓ Start with one box per cat plus one extra
✓ Boxes in a row may count as one location
✓ Large uncovered boxes suit many cats
✓ Sudden avoidance needs a health check
One box per cat plus one extra is a useful starting point, but number alone is not enough. Boxes need to be in separate, safe, accessible locations to function as real choices.
Count locations, not furniture
Three trays side by side offer little protection if another cat blocks the room. Spread options across the home and, when relevant, across different floors.
Choose safe access
Avoid noisy appliances, trapped corners and busy feeding areas. A cat should be able to see an approach and leave without passing a rival.
Fit the cat
The tray should be large enough to turn and dig comfortably. Seniors and cats with pain may need a low entry while still benefiting from high sides elsewhere.
Maintain without perfume
Scoop at least daily, wash with mild unscented products and avoid sudden litter changes. Strong fragrance can be aversive.
Test access from the cat’s point of view
Walk each route at the times your cats normally toilet. Check closed doors, stairs, appliances, narrow hallways and places where another cat can stare or wait. A useful box has a calm approach and an exit that cannot easily be controlled by a housemate.
Adjust the formula for the individual
The one-per-cat-plus-one rule is a starting point, not a maximum. Kittens, seniors, cats with pain and homes with several levels may need additional low-entry options. Sudden avoidance, straining, blood or repeated visits needs veterinary assessment rather than another tray alone.

Questions cat people ask
Do two cats really need three litter boxes?+
One per cat plus one extra is a useful starting point, but distribution matters more than the arithmetic alone. Separate locations reduce blocking and offer meaningful choice.
Where should litter boxes be placed?+
Choose quiet, accessible places away from food and noisy appliances, with visibility and a safe exit. Seniors or painful cats may also need low-entry options on each level.

Some healthy cats simply do not cover stool. A change can also reflect a small or dirty box, disliked litter, social pressure, pain or urgency.
