How to choose the right cat litter box
Updated June 2026Independently researchedNo paid placement.
The best cat litter box for you depends on your cat’s personality, your cleaning habits, and your home space. For most households, a large, open box with unscented clumping litter and daily scooping works well, but self-cleaning models can be a game-changer for busy owners. Focus on size, ease of cleaning, and odor control features rather than flashy extras.
What type of litter box is best for your cat?
Covered boxes offer privacy and contain odors, but some cats feel trapped or claustrophobic, especially in small, dark enclosures. Open boxes are less intimidating and give cats a full view of their surroundings, which reduces ambush stress in multi-pet homes. Top-entry boxes cut down on tracking because cats have to jump out over a rim, and they also keep dogs out of the litter. If your cat tends to spray or kick litter everywhere, a high-sided open box or a top-entry design is a practical compromise. Kittens, elderly cats, or cats with mobility issues may struggle to climb into high-sided or top-entry boxes, so consider their physical needs before choosing a style. A good rule: offer one covered and one open box and see which your cat prefers.
How big should a litter box be?
Size matters more than most owners realize. A box should be at least one and a half times the length of your cat from nose to tail tip. Standard store boxes are often too short for large cats, leaving them cramped and causing them to perch on the edge or eliminate over the side. This is especially common with breeds like Maine Coons, Ragdolls, or heavy-boned domestic cats. For a comfortable fit, look for a box that is wide enough for your cat to turn around fully and deep enough to hold several inches of litter. Many cats prefer at least four inches of litter depth for digging and covering. If you have multiple cats, larger box sizes help reduce territorial disputes and keep the space cleaner between scoopings.
Self-cleaning vs manual: which is worth it?
Self-cleaning boxes, like those from Litter-Robot or ScoopFree, automate waste removal and can dramatically reduce daily chores. They are best for owners with busy schedules or those who travel often. The convenience comes with a higher upfront cost, ongoing expenses for proprietary waste receptacles or special litter, and occasional mechanical issues that require troubleshooting. Manual boxes are far cheaper, simpler, and more reliable – there’s no motor to break and no special parts to replace. A good manual box with a sturdy scoop and a metal litter sifter can last for years. The trade-off is that you need to scoop at least once a day and do a full dump and clean every couple of weeks. If you dislike daily scooping, an automatic box can be a worthwhile investment, but be prepared to spend a few hundred dollars and to monitor your cat’s acceptance of the noise and motion.
What features reduce litter tracking?
Tracking is the top complaint among cat owners, and no single solution eliminates it entirely. High walls or a top-entry design keep litter from being kicked out, while a quality mat placed just outside the box catches grains from paws. Look for mats with a textured or honeycomb surface that traps litter rather than just a flat rubber pad. Some boxes come with built-in ramps or grated steps that allow litter to fall back into the box as your cat exits. You can also reduce tracking by choosing larger, heavier litter granules – pine pellets or paper pellets track less than fine clumping clay, though some cats dislike the texture change. Placing the box in a low-traffic area away from walls also gives cats room to shake off litter before stepping away.
How many litter boxes do you need?
The standard rule of thumb is one litter box per cat plus one extra. So for two cats, you should have three boxes. This helps prevent competition, gives shy cats a safe option, and ensures there’s always a clean box available if one gets soiled. In multi-story homes, place at least one box on each floor. Boxes should be spaced apart, not clustered in one corner, to reduce the chance of one cat guarding access. If you live in a small apartment, you may be able to get away with fewer boxes if you scoop twice daily, but always err on the side of more. A single cat can still benefit from having two boxes – some cats prefer one box for urine and another for stool.
What about odor control?
Odor control starts with the litter itself, not the box design. Clumping clay litters with activated charcoal or baking soda are effective at trapping smells between scoopings. Silica gel crystals absorb moisture and odors but can be dusty and some cats dislike the feel. Natural litters like pine, corn, or walnut are generally less effective at odor neutralization unless you scoop very frequently. Covered boxes contain odors but can also concentrate them, making the inside unpleasant for your cat. Most covered boxes have a charcoal filter slot – replace those filters every one to two months or they become useless. Enclosed spaces also trap ammonia fumes, which can irritate your cat’s respiratory system, so proper ventilation is key. For serious odor issues, consider a stainless steel box because the non-porous material doesn’t hold onto smells like plastic does, though they are more expensive and can be noisy when litter is dumped.
Frequently asked questions
How often should I fully clean and change the litter?
For clumping litter, scoop solid waste and clumps daily, and completely empty, wash, and refill the box every two to four weeks. For non-clumping or pellet litters, a full change is needed more often, typically every week to ten days.
Is a covered litter box bad for a shy cat?
Not necessarily, but some shy cats feel trapped in a covered box because they can’t see an approaching threat. If you have a nervous cat, provide an open box as an alternative and observe which one she uses more. A covered box with a large entrance and a clear front flap can offer privacy without the feeling of confinement.
What type of litter works best with automatic litter boxes?
Most self-cleaning boxes are designed for clumping clay litter – fine-grain clumping clay works best to form solid waste clumps that the mechanism can remove. Avoid lightweight litters, crystal litters, or natural pellet litters unless the manufacturer specifically approves them, as they can clog or jam the rake or sifter.
Do kittens need a special kind of litter box?
Kittens do best with a low-sided, open box that they can easily step into – a cardboard box with low sides or a small plastic tray works well for the first few weeks. Avoid covered boxes for kittens because they can be scary and hard to enter. Use a non-toxic, unscented litter until the kitten is at least four months old.
How do I transition my cat from a old box to a new one?
Place the new box next to the old one for at least three to five days, using the same litter brand in both. Gradually move the old box farther away each day until it is no longer needed. You can also try putting some of your cat’s waste into the new box to signal that it is a bathroom spot. Never force your cat into the new box.
Are stainless steel litter boxes worth the extra cost?
For owners who struggle with lingering odors or plastic scratches that trap bacteria, stainless steel boxes are a big upgrade. They are non-porous, easy to sanitize, and can last for years without absorbing smells. The downsides are a higher price tag, a slight metallic echo when litter is poured, and fewer shape and size options compared to plastic.
