Choosing a litter box: practical standards for size, entry and placement
Choose a litter box about 1.5× body length, with entry height suited to age, one per cat plus one spread out, away from food and water and sudden appliances, and scoop daily.
Step-by-step checklist
- 01 Box length about 1.5× nose-to-tail-base length
- 02 Width allows a full turn
- 03 Low entry for kittens, seniors and arthritic cats
- 04 One box per cat plus one, spread out
- 05 Away from food, water and sudden appliances
- 06 Scoop daily; litter depth 3–5 cm

Size comes first. A box should be about 1.5 times the cat’s length from nose to tail base, and wide enough for a full turn. Many boxes labelled “large” are still too small for adult males, so cats stand on the edge or urinate outside.
Choose entry height by age and joint health. Kittens, seniors and cats with arthritis need low entries. High sides reduce tracking, but only if the cat is willing to step over them. A cut-down storage bin is a low-cost way to get a genuinely large box.
Covered boxes are neither universally good nor bad. They contain odour and tracking but reduce ventilation and deter some cats. In multi-cat homes, open boxes are easier to monitor and clean promptly.
Provide one box per cat plus one, spread across different locations rather than lined up together. Choose quiet spots with an escape route, away from food and water and away from appliances that start suddenly.
Litter depth is usually 3–5 cm. Scoop daily and replace litter thoroughly on a regular schedule. Avoid frequent litter type changes; if a change is necessary, mix gradually to give the cat time to adjust.
Owner questions
Are covered litter boxes good or bad?
It depends on the cat. They contain odour and tracking but reduce ventilation; if the cat avoids them or there is multi-cat tension, prefer open boxes.
How large should a litter box be?
About 1.5 times the cat’s nose-to-tail-base length, wide enough for a full turn. Adult males often need more than a standard “large” box.
How often should litter be fully replaced?
Scoop solids and clumps daily, and replace and clean thoroughly on a regular schedule. Frequency depends on the number of cats, litter type and use.
