Pick the largest open box your space allows, with low enough sides for your cat to enter easily, and add one more box than you have cats. Choosing a litter box means matching size, entry height, and style to your cat while keeping the setup easy to clean and easy for the cat to reach. Most litter-box problems trace back to a box that is too small, too enclosed, or too hard to get into, so those three factors carry most of the decision.
Quick Answer
Choose a box at least one and a half times your cat’s length, with low sides for easy entry, in an open style most cats prefer. Provide one box per cat plus one, placed in quiet, accessible spots. Size and access matter more than any feature.
Key Takeaways
- Bigger is better: aim for at least 1.5 times your cat’s body length.
- Low entry helps kittens, seniors, and any cat with stiff joints.
- Most cats prefer open boxes over covered ones.
- Provide one box per cat, plus one extra.
- Placement in quiet, accessible spots is part of the choice.
What to Prioritize When Choosing a Litter Box
| Factor | What to look for | Why it matters |
|---|---|---|
| Size | 1.5x cat’s body length or more | Room to turn and dig prevents avoidance |
| Entry height | Low for kittens and seniors | Easy access keeps the box usable |
| Style | Open preferred by most cats | Sightlines and escape reduce stress |
| Number | One per cat, plus one | Prevents competition and accidents |
| Placement | Quiet, accessible, low-traffic | Cats avoid noisy or cornered spots |
Get the Size Right First
Size is the factor owners most often get wrong. A box should be at least one and a half times the length of your cat from nose to tail base, giving room to turn, dig, and position without hanging over the edge. Cramped boxes lead to messes over the side and, worse, to a cat deciding the box is not worth using. Many boxes sold as standard are too small for an adult cat, so err large. A big storage tote often makes a better box than a purpose-sold small one. Litter boxes for small spaces covers fitting a roomy box into a tight home.
Match Entry Height to Your Cat
Entry height decides whether some cats can use the box at all. High sides contain litter well but block kittens, senior cats, and any cat with arthritis or stiff joints. A cat that has to strain or jump to get in may start going elsewhere. For young, old, or less mobile cats, a low-entry box removes that barrier. Healthy adult cats handle higher sides fine, which help with scatter, so match the entry to the cat rather than to the litter mess. Low-entry boxes for seniors covers the accessible options.
Choose Open Over Covered for Most Cats
Style comes down to open versus covered, and most cats prefer open. Open boxes give clear sightlines and an easy escape, which cats value as both predator and prey. Covered boxes contain odor and mess for the owner but trap odor inside and can feel like a trap to the cat. Unless your cat has shown it likes a hood, an open box is the safer default. If containment matters, size up a covered box generously rather than buying a standard one. Our covered vs uncovered comparison covers this in depth.
Get the Number and Placement Right
How many boxes and where they go is part of choosing well. The standard is one box per cat plus one, so two cats need three boxes, which prevents competition and gives each cat a reliable option. Placement matters as much: cats want boxes in quiet, accessible, low-traffic spots, away from their food and from noisy appliances. A box in a cramped, loud, or cornered location gets avoided no matter how good the box is. Spread boxes across the home rather than lining them up in one room, since boxes clustered together count as one location to a cat and defeat the purpose of having several. Multi-cat litter box setups cover homes with several cats.
Consider Cleaning and Litter Type
A box you can keep clean easily is a box that stays used. Simpler shapes with fewer crevices are quicker to scoop and scrub, and a box that is easy to service tends to get serviced more often. The litter you pair with it matters too, since clumping litter makes daily spot-cleaning fast. Whatever the box, scooping at least once a day keeps a cat happy with it, and a full litter change every week or two keeps odors from building. High-sided or covered boxes trap more residue in corners, so factor cleaning effort into the style you pick, not just the purchase. A litter mat under the box catches tracked litter and cuts cleanup. Clumping litter covers the fast-cleaning option.
Putting the Choice Together
Start with the largest open box your space allows, check that your cat can enter it easily, and provide one more box than you have cats in quiet, reachable spots. Those decisions prevent the great majority of litter-box problems. Features like hoods and liners are secondary to size, access, and cleanliness, and chasing them while getting the basics wrong is how owners end up with an avoided box. Nail the fundamentals of size, access, cleanliness, and number, and everything else is simply preference. Caring for an indoor cat covers the surrounding routine.
Skip the Features That Cause Problems
Some litter-box add-ons work against you. Liners tear as cats dig and bunch up, trapping urine and annoying the cat, so most owners are better off without them. Self-cleaning boxes appeal to busy owners but can frighten some cats with their noise and motion, and they fail if the cat distrusts them. Box fresheners and heavily scented litters can smell pleasant to people while deterring a cat whose nose is far more sensitive. Simpler is usually better: a plain roomy box, unscented clumping litter, and daily scooping beat gadgets. A litter deodorizer used sparingly is gentler than a scented litter. Clumping vs non-clumping litter covers the fill choice.

How to Choose a Litter Box FAQ
What size litter box should I get?
At least one and a half times your cat’s length from nose to tail base, so the cat can turn and dig without hanging over the edge. Most standard boxes run small, so err large. A big storage tote often beats a purpose-sold small box.
Are covered or open litter boxes better?
Most cats prefer open boxes for the sightlines and easy escape. Covered boxes suit owners wanting odor and mess control, but they trap odor inside and can deter some cats. Default to open unless your cat has shown it likes a hood.
How many litter boxes do I need?
One per cat, plus one. So one cat needs two boxes and two cats need three. Extra boxes prevent competition, give each cat a reliable option, and reduce accidents, especially in multi-cat homes where one box invites conflict.
What entry height is best?
It depends on the cat. Kittens, seniors, and cats with stiff joints need low entry to get in without straining. Healthy adults handle higher sides, which help contain litter. Match the entry height to your cat’s mobility rather than to scatter control.
Where should I put the litter box?
In quiet, accessible, low-traffic spots away from food and noisy appliances. Cats avoid boxes in cramped, loud, or cornered locations. Spread boxes around the home rather than clustering them, so a cat always has a reachable, calm option.
How often should I clean it?
Scoop at least once a day, and wash the box periodically. A clean box is one of the biggest factors in whether a cat keeps using it. Clumping litter makes daily scooping quick, and an easy-to-clean box shape encourages regular servicing.
Why does my cat avoid a brand-new box?
Often it is too small, too enclosed, hard to enter, or badly placed. Check size, try removing a hood, lower the entry, or move it somewhere quieter. Sudden avoidance with no obvious box cause can signal a health issue worth a vet visit.
