About Cat Litter Boxes
The most common reason cats avoid a litter box is that it is too small or not clean enough. A box around 1.5 times the length of your cat, scooped daily, solves most problems before any feature does.
Our lists cover simple open pans, covered boxes, top-entry designs and self-cleaning units for busy households.
How to choose a litter box
Size
Bigger is almost always better. Many standard boxes are too small for large cats, so storage tubs are a common workaround.
Open vs covered
Covers contain litter scatter and hide the view, but trap odor inside, which some cats dislike. Try an open box first if your cat is hesitant.
Entry height
Kittens and senior cats with stiff joints need a low entry. Top-entry boxes reduce tracking but are hard for older cats.
Self-cleaning boxes
Automatic boxes save daily scooping but cost more, need specific litter in some cases and can scare nervous cats. Check the minimum cat weight for the sensor.
How many boxes
A common guideline is one box per cat plus one, placed in quiet spots away from food and water.

Answers
Cat Litter Boxes: common questions
What is the best cat litter boxe to buy?
One of our strongest picks is the CATLINK Luxury Self-Cleaning Litter Box, a standout in our Best Cat Litter Boxes for Multi-Cat Households in 2026 list. The PetSafe ScoopFree Ultra is another excellent choice.
How do I choose the right cat litter boxes?
Start with your main use and budget, then compare our shortlists: Best Cat Litter Boxes for Multi-Cat Households in 2026, Best Cat Litter Boxes for Odor Control in 2026, Best Cat Litter Boxes for Senior Cats in 2026.
What should I look for when buying cat litter boxes?
Bigger is almost always better. Many standard boxes are too small for large cats, so storage tubs are a common workaround.
How many litter boxes do I need for multiple cats?
The standard rule is one box per cat, plus one extra. Two cats need three boxes, three cats need four. This applies even with a self-cleaning box, because cats can be territorial about a shared box regardless of how often it cycles. If space is the constraint, a single high-capacity automatic box like the CATLINK Luxury Self-Cleaning Litter Box reduces how strictly you need to follow the rule, but it does not eliminate the need for at least two access points in a two-cat home.
Do automatic litter boxes work for multiple cats?
Yes, and they are usually a better fit for multi-cat homes than manual boxes, since the automatic cycle after each use means the next cat rarely encounters a dirty box. The limiting factor is waste bin capacity. A small waste drawer fills up fast with two or more cats using it daily, so check the rated capacity (in cycles or days) against your household size before buying.
Can two cats share one self-cleaning litter box?
Two cats can share one automatic box, but it depends on the cats. Some pairs share without issue, especially littermates or bonded cats. Others will avoid a box that smells like another cat's waste even seconds after cleaning. If you notice one cat avoiding the box or holding it, add a second box in a different room rather than assuming the automatic cycling alone will solve it.
What litter box capacity handles 3 or more cats?
For 3 or more cats, prioritize waste bin size over the base unit price. The CATLINK Luxury Self-Cleaning Litter Box's globe design and larger waste drawer handle several days between drawer changes even with 3 cats, while smaller disposable-tray systems like the ScoopFree Ultra need tray changes every few days in the same household. Pair any single automatic box with at least one additional box for a 3-cat home.
What litter box controls odor the best?
Boxes that seal or remove waste quickly after use control odor better than boxes where waste sits exposed until scooped. The CATLINK Luxury Self-Cleaning Litter Box's sealed waste drawer and the PetSafe ScoopFree Ultra's crystal litter, which dehydrates solid waste and absorbs moisture, both outperform a standard open litter pan for controlling smell between cleanings.
