Choosing the right litter box setup for your cat can make a big difference in your home’s cleanliness and your cat’s comfort. This guide covers the number of boxes you need, the best size and style, where to place them, and how to keep them clean so your cat actually wants to use them.
How many boxes
A widely recommended rule of thumb is to have one litter box per cat plus one extra. For a single cat, that means two boxes. For two cats, three boxes. This guideline helps reduce competition and gives each cat options, especially in multi-level homes or households where cats have different preferences.
Having multiple boxes also provides a backup if one box becomes dirty or if a cat decides to avoid a particular location. Some cats are territorial about their bathroom space, and extra boxes can prevent conflicts. If you have cats that do not get along, placing boxes in separate areas is even more important.
If you live in a small apartment, two boxes may feel like a lot, but even one extra box can make a difference. You can place them in different rooms or at opposite ends of a room to give your cat choices.
Size matters
Cats generally prefer a litter box that is large enough for them to turn around, dig, and squat comfortably. A common rule of thumb is that the box should be at least one and a half times the length of your cat from nose to the base of the tail, which is longer than many standard boxes.
Many standard litter boxes are smaller than this, so you may need to look for a larger option. If you have a large breed cat, such as a Maine Coon, or a cat that is long-bodied, you may need an extra-large box. Some cats prefer a box with higher sides to prevent litter from being kicked out, but the entrance should still be low enough for easy access.
If you are unsure about size, you can try a storage tub or a cement mixing tray as a temporary box to see if your cat prefers more space. Just make sure the sides are not too high for your cat to step over comfortably. For older cats or cats with mobility issues, a lower entry is essential.
Open, covered or top-entry
Open litter boxes
Open litter boxes are the simplest and most popular style. Many cats prefer them because they offer a clear view of their surroundings, which helps them feel safe while using the box. Open boxes are also easier for you to clean and scoop. The main downside is that litter can be kicked out, and odors may be more noticeable.
Covered litter boxes
Covered boxes have a hood or dome that encloses the box. They can help contain litter scatter and reduce odors, but some cats dislike them because the enclosed space can trap smells and feel confining. If your cat is nervous or has been startled while inside a covered box, they may avoid it. If you choose a covered box, make sure it is large enough and well-ventilated, and clean it frequently.
Top-entry litter boxes
Top-entry boxes have an opening on the lid instead of the side. Cats jump onto the lid and drop down into the box. This design can reduce litter tracking because cats have to jump out onto a mat, and it also keeps dogs or young children out of the box. However, top-entry boxes may not be suitable for older cats, kittens, or cats with joint problems who have trouble jumping. Some cats also dislike the feeling of being enclosed.
Ultimately, the best style depends on your cat’s personality. If you notice your cat hesitating to use a covered or top-entry box, try switching to an open one.
Self-cleaning boxes
Self-cleaning litter boxes automate the scooping process by raking or sifting waste into a sealed compartment. They can be convenient for busy owners and help keep the box clean between manual scoops. However, they are not right for every cat.
Some cats are frightened by the noise or movement of the self-cleaning mechanism. If your cat is skittish, introduce the box slowly and leave it unplugged for the first few days so your cat can get used to it. Some models have a delay or sensor that waits for the cat to leave before cleaning, which can help reduce stress.
Self-cleaning boxes also require regular maintenance, such as emptying the waste compartment, adding fresh litter, and cleaning the mechanism. They can also be more expensive to operate because you need to buy compatible litter or refill cartridges. If you have multiple cats, you may still need more than one box, and self-cleaning models may not handle heavy use as well as traditional boxes.
For cats that are sensitive to change, a simple open box with regular scooping is often the most reliable choice.
Litter basics
The type of litter you choose can affect how often your cat uses the box and how easy it is to clean. Most litters fall into a few categories: clumping clay, non-clumping clay, silica gel crystals, and plant-based options such as pine, corn, or paper.
Clumping clay litter is popular because it forms solid clumps that are easy to scoop, and it controls odor well. Non-clumping clay absorbs moisture but does not form clumps, so you need to change the entire box more often. Silica gel crystals absorb moisture and control odor without clumping, and they can last longer between changes, but some cats dislike the texture.
Plant-based litters are biodegradable, but their clumping ability and odor control vary. Some are marketed as flushable, yet many local water agencies advise against flushing cat waste, so check your local guidance first. Some cats are picky about texture, so you may need to try a few types to see what your cat prefers. A general rule is to avoid heavily scented litters, as many cats find strong fragrances off-putting.
Whichever litter you choose, maintain a depth of about two to three inches. Too little litter can make cats uncomfortable, while too much can lead to waste being buried too deep to scoop easily.
Where to put the box
Placement is just as important as the box itself. Cats prefer quiet, low-traffic areas where they will not be startled while using the box. Avoid placing the box near loud appliances like washing machines or dryers, or in busy hallways. A corner of a spare bedroom, a quiet bathroom, or a laundry room corner can work well.
Keep the litter box away from your cat’s food and water bowls. Cats are naturally clean animals and prefer to eliminate away from where they eat. If possible, place the box in a different room from the feeding area.
In a multi-story home, it is a good idea to have at least one litter box on each floor. Cats may not want to travel far to reach a box, especially if they are older or have health issues. A box on each floor makes it easy for them to find a spot quickly.
If you have multiple cats, place boxes in different locations rather than side by side. This gives each cat a sense of territory and reduces the chance of one cat blocking access to the box.
To help keep the area tidy, place a litter mat under and around the box to catch stray granules.
Cleaning routine
A clean litter box is essential for encouraging your cat to use it consistently. Scoop the box at least once a day, and ideally twice if you have multiple cats. Clumping litter makes this easy: remove solid waste and clumps, and dispose of them in a sealed container.
Once a week, empty the entire box, wash it with mild dish soap and warm water, and dry it thoroughly before adding fresh litter. Avoid using harsh chemicals or strong-smelling cleaners, as the residue can deter your cat. A mixture of water and white vinegar is a safe, effective cleaner that neutralizes odors without leaving a strong scent.
Replace the litter box itself when it becomes scratched or worn, because scratches can trap bacteria and odors.
Using a sturdy scoop with a deep bowl makes daily scooping faster and less messy.
When a cat avoids the box
If your cat suddenly stops using the litter box, it is important to take it seriously. The first step is to rule out a medical problem. Urinary tract infections, bladder stones, kidney disease, and other conditions can cause pain or urgency that leads to accidents. If your cat is straining to urinate, crying out in the box, or urinating in unusual places, contact your veterinarian promptly. Male cats that cannot urinate are a medical emergency.
If your vet gives your cat a clean bill of health, look at environmental factors. Have you changed the type of litter, moved the box, or added a new pet or person to the household? Cats are sensitive to change, and even small adjustments can cause stress. Try returning to the previous litter type, adding an extra box, or moving the box to a quieter location.
Check the box itself. Is it clean enough? Is it too small or too deep? Does it have a strong odor? Sometimes a simple change, like switching to a larger open box or using unscented litter, can solve the problem.
If the problem persists, consider adding more boxes in different locations and using enzyme-based cleaners to thoroughly remove any urine or feces marks from accident spots. Cats are drawn to the smell of their own waste, so if an area smells like a bathroom, they may continue to use it.
