The 8 Best Cat Litter Boxes of 2025

The best cat litter boxes come in a wide range of styles, from simple high-sided pans to high-tech self-cleaning boxes. When choosing one for your cat, there’s a lot to consider, from their unique preferences to the specific needs of your household. Regardless of the type, the litter box should be comfortable for your cat and easy for you to keep clean.

Over the past few years, we’ve tested 38 different litter boxes and consulted veterinarians and cat behaviorists to understand what features are best for cats of all ages and needs, including seniors, large breeds, and multi-cat homes. Molly DeVoss, a certified cat behavior specialist, says a litter box should be at least 1.5 times the length of your cat, measured from the nose to the base of the tail. Unfortunately, most traditional boxes are much too small.

After thorough testing with four different cats, our top pick is the Frisco High Sided Extra Large Cat Litter Box. It is a comfortable size that suits many cats, and its 10-inch-high sides help prevent litter scatter. However, if you have a larger cat, one with limited mobility, or your own unique needs, we also recommend several options that may strike a good balance between your needs and those of your cat.

Best overall

While house cats vary in size, most commercial litter boxes don’t give them enough room to do their business, including circling and digging. The Frisco High Sided Extra Large Litter Box gives most cats the room they need with a 24-by-18-inch footprint and 10-inch high sides to help contain mess. The 5.6-inch entrance might be a little high for cats with mobility issues, but with a $23 price tag, it might leave room in the budget for a ramp, or you can cut a lower entrance and cover the edges with duct tape.

We like its simple design, too. When it comes to litter boxes, simpler is better, say Dr. Wailani Sung, a certified veterinary behaviorist and senior director of animal admissions and wellbeing at Joybound People & Pets, and cat behaviorist Daniel “DQ” Quagliozzi, a certified feline behavior and training specialist. Fewer crevices mean fewer spots for urine and odors to build up and less scrubbing for you. That’s important, says Dr. Elena Shirley, lead veterinarian and partner at CityVet in Charlotte Uptown, who recommends changing the litter weekly and deep cleaning the box with soap and water every four to six weeks. This box is made from smooth, BPA-free, recyclable plastic that resists sticking, making daily scooping and deep cleaning quick and easy.

This litter box doesn’t come with a cover, and that’s a good thing. “Most cats prefer litter boxes that are uncovered,” says Samantha Bell, a cat enrichment expert at Best Friends Animal Society. Covers trap ammonia smells, making the box unpleasant for cats. Open litter boxes also provide cats a clear view and easy escape routes, helping them feel more secure.

Best for large cats

If you have a large cat, you need an even larger litter box. When a litter box is too small, your cat might perch on the edge, be smooshed against the sides, unable to turn around, dig outside the box, or worse, go somewhere else, DeVoss says. She recommends the Kitty Go Here Jumbo Litter Pan, which is our top pick among the best large litter boxes.

At about $70, it is pricier than other traditional boxes. However, DeVoss says it’s well worth the price for its size and functionality. Measuring more than 1.5 times the length of an 18-inch cat, many larger cats can comfortably stretch out and cover their waste in this box. “Cats are indeed different sizes, so you’ll need to measure,” she says. Large cat breeds like Ragdolls, Norwegian Forest Cats, and Savannahs are larger than the average kitty, but often still fit comfortably in an extra-large box like this one. For jumbo kitties like the Maine Coon, we recommend a larger DIY box, like the one we picked for this guide.

The Kitty Go Here Jumbo Litter Box has relatively high ramped sides to decrease litter scatter from the sides. However, you may want to pair this box with one of the best cat litter mats to catch any stray litter that might tumble from the low entry. The pan is made from durable plastic that is easy to clean and has an oversized rim for easy lifting.

Best low-entry for seniors and kittens

In some cases, short- or long-term medical conditions can influence the best litter box choice, Shirley says. DeVoss says that a box with a low entry is even better than ramps or stairs. My 6-year-old cat, Lyra, has a bad knee and early-onset arthritis, so I prefer low-profile boxes that she can step in and out of comfortably.

The Kitty Go Here Senior Cat Large Litter Box features a 3-inch-tall front entry for easy access. Even with a low entry, some cats — like mine — still hop over litter box sides. “Cats are masters at hiding their pain,” says Dr. Carly Fox, a senior veterinarian at the Schwarzman Animal Medical Center. They may also not recognize their own limitations. That’s why I like the short 5-inch rim on this litter box in addition to its low entry point — it can help reduce overexertion, no matter the route taken. That said, I was pleasantly surprised to see my cat gingerly walk out from the entrance of this litter box, perhaps because it’s a generous 11 inches wide. DeVoss says there’s no such thing as too big of a litter box, making this model a great choice for itty-bitty kittens, too.

A downside of this box is that the low entryway limits the litter depth. Some cats prefer digging in a few inches, but the fill line on this box sits at about an inch. I filled it just slightly higher than the line, and while litter reached the edge of the entry after my cats used it, none actually tumbled out. However, an aggressive digger would likely cause some litter to spill from the entryway. In addition, shallow litter depth means less clean litter is available for your cat after elimination, so cat parents with this box should scoop more frequently. To prevent litter scatter, I recommend pairing the box with a litter mat, such as the Gorilla Grip Cat Litter Trapping Mat.

Best stainless steel

The durable stainless steel Frisco litter box offers a significant advantage over traditional plastic litter boxes — it’s highly resistant to accumulating scratches. Scratches in a litter box can become breeding grounds for bacteria and unpleasant odors, no matter how diligently the box is cleaned.

“Once you see scratches on the bottom of the box, it is time to replace it,” DeVoss says. Since plastic boxes are prone to scratches, they typically need to be replaced every six months. To combat this issue, DeVoss recommends stainless steel litter boxes that hold up to a cat’s claws. The downside of a stainless steel litter box is that it amplifies sound, which can be off-putting for noise-sensitive cats and people alike.

The pan provides ample space for small and medium cats at an affordable price — about $45. It has a nonskid base that ensures it stays securely in place, even during enthusiastic digging sessions or post-bathroom zoomies. However, it doesn’t have a tapered entry, which may make it challenging for seniors, kittens, and cats with limited mobility to access the box.

Best DIY

When it comes to creating a DIY litter box, a wide, flat plastic storage container is an ideal and cost-effective stand-in for a traditional box. In fact, Quagliozzi and Sung often recommend their clients consider this DIY version since many traditional litter boxes are too small for more than one cat to use several times a day.

The Sterilite 41-Quart Storage Box is made from durable, clear plastic. Its interior dimensions of 29 3/8 inches by 18 inches provide a cat with plenty of room to perform natural behaviors like digging and covering their waste. A box this big is especially important for extra-large breeds such as the Maine Coon, the biggest domestic cat, which can reach up to an astonishing 40 inches in length. Because the box is waterproof, it won’t leak any excess urine that goes uncaptured by the litter.

With 6-inch-high sides, the box is shallow enough for most cats to enter and exit easily, but you can also cut a low front entry. We recommend using wire cutters to cut the entrance to your desired height and width and taping over the edges with duct tape. People with cats that aggressively scratch and kick their litter may need to do more floor cleanup than they would with a litter pan with higher sides.

Best automatic

The fourth version of Litter-Robot is a reliable machine that cleans itself and notifies you when it’s time to empty the waste drawer or replace litter. You can also add a LitterHopper for automated litter replenishment. Insider Reviews senior reporter James Brains says his cats took to this automatic box after four days of encouragement and have used it exclusively ever since. Similarly, my cats also happily use the Litter-Robot boxes, including previous generations 2 and 3.

The Litter-Robot 4 runs a cleaning cycle a few minutes after a cat leaves the box, so even cats in multi-cat households will never be without a clean litter box. Thanks to laser-light technology, the cylinder stops cycling if a cat enters while the cleaning cycle is running. The machine also weighs your cat every time they enter, recognizing each cat by body weight so owners can assign profiles and monitor individual bathroom activity — one of 11 optional push notifications.

The machine sifts waste into a lined tray that you’ll need to empty every week to two times a week, depending on the frequency of use. Even if the waste bin isn’t full, emptying it proactively is recommended because cats have a heightened sense of smell. Brains says he received cleaning notifications before they seemed necessary and found that if he shook the drawer to distribute the waste more evenly, the sensor would reset. The “empty” cycle works well to remove all the litter when it needs replacing, but Brains still wipes down stuck-on debris inside and deep cleans the globe every one to three months. Weight monitoring is only accurate when the machine is placed on a hard floor or a Litter-Robot Carpet Tray. Nonetheless, we consider this self-cleaning litter box worthy of the investment.

If your cat is small or has mobility issues, you can add an attachable ramp. However, the ramp still has a 5-inch rise from the floor to the first step, so it’s not going to work for every cat. The biggest downside is the Litter-Robot 4’s high cost ($700), but it comes with a one-year warranty. If you or your cat isn’t happy with the Litter-Robot 4, you can also return it within 90 days for a refund, although return shipping will be deducted.

Best covered

What a cat desires in a litter box often differs from what appeals to us humans. Case in point, covered litter boxes. While they hide mess and odors from us, they’re far from feline-friendly. “Cats dislike covered boxes because this blocks the visual field,” says Rachel Geller, a certified cat behavior and retention specialist and founder of All Cats All the Time, Inc. In multi-cat homes and ones with dogs, it’s even more important for cats to have a clear view of their surroundings. Plus, the trapped odors inside a covered box can quickly turn it into a place cats avoid.

That said, some cats don’t mind a covered box — as long as it’s large, clean, and comfortable. That’s why we chose the Frisco Extra-Large Hooded Cat Litter Box as the best covered litter box option. It has a larger interior compared to other covered boxes and a removable cover, giving you the flexibility to adjust the setup if your cat is hesitant. With the cover in place, a built-in charcoal filter provides extra odor control between cleanings. Even without the cover, the high sides help contain messes, which is especially useful for cats who tend to “elevator pee.”

The box has a semiopaque plastic door to help prevent odors from escaping. As you might guess, that just traps smells inside with your cat and can make the space feel even more confining. For these reasons, we recommend removing the door, which easily snaps off.

Best top-entry

Sung and Quagliozzi say cats need choices to feel secure, which includes having at least two litter box areas per cat in your home. Having more than one way in and out of a box can also make a big difference. While an uncovered box with unlimited exit routes is best, a covered box with both a top and side entrance gives your cat more control over how they come and go. For this reason, Modkat’s XL Litter Box is our top recommendation for the best top-entry litter boxes.

If you’d prefer your cat not use the front entry, you can close the built-in sliding door, though we don’t recommend it. The lid folds back for easy cleaning, and litter tracked onto the roof returns to the pan through perforations. The box comes with two reusable plastic liners and a scoop. However, Bell advises against using litter box liners. “Cats often get their claws stuck in the liner, tearing a hole in it, which causes them to dislike the box,” she says.

A downside of the Modkat XL is its price, typically $190. It’s one of the roomiest top-entry models available, but if you’re looking for a larger box, we recommend a traditional open-top pan.

What to look for in a cat litter box

The best cat litter boxes are spacious, easy for a cat to access and designed to fit their preferences, and simple for guardians to maintain.

Size: Sung says cats need a space at least 1.5 times their length to scratch at the litter and bury their waste. Many litter pans advertised as “large” or “jumbo” have far smaller dimensions than our top picks. You can determine whether a box is big enough by measuring your cat’s length from its nose to the base of its tail and comparing it to the dimensions of the box.

Accessibility: Not every cat is agile or motivated enough to jump up into a litter box, and top-entry boxes can be especially challenging for some cats to access. When selecting a box, consider your cat’s mobility needs. Kittens, senior cats, and those with injuries or mobility limitations may benefit from a box with an entry height of about 3 inches or less. If choosing a box with a high entry and sides, look for one made of a material that you can safely modify to create a lower entry that better suits your cat’s needs.

Design: Quagliozzi says cats prefer a box that doesn’t distract them from their business or require them to contort their body into unnatural positions. Look for boxes that offer easy entry and allow a cat to stand flat on all four paws rather than curved or angled boxes. An open-topped litter pan is the most universally accepted by cats of all types. Some cats may be intimidated by hooded or covered litter boxes, especially if the top is low enough that the cat must crouch to do their business.

Ease of cleaning: In general, the more simple the design of a box, the easier it will be to clean. Litter boxes should be scooped at least once a day, though more frequent scooping is ideal. Geller says healthy adult cats typically use the litter box two to five times a day for both peeing and pooping. However, factors like age and health can influence this. Senior cats may urinate more often due to conditions like kidney disease while kittens usually urinate after each feeding and may poop up to three times a day. If having a cover over your litter pan makes you forget to scoop it daily, then a litter box without a hood is a more hygienic option. If you struggle to scoop your litter box daily, an automatic or smart litter box may be the best option, though even self-cleaning litter boxes still require deep cleaning. Our experts say you’ll also need to deep clean your litter boxes every four to six weeks using water and unscented dish soap.

Material: We included metal and plastic options in this guide to the best cat litter boxes. Plastic litter boxes have a lower upfront cost, but our experts recommend replacing them every six months or at the first sign of scratch marks. DeVoss says that no matter how well the box is cleaned, scratch marks accumulate bacteria and, therefore, odors. On the other hand, stainless steel and metal litter boxes may have a higher initial cost, but they offer a longer lifespan compared to plastic options. However, noise-averse people and cats alike may dislike the sound of cat claws on metal.

How we selected the best cat litter boxes

Over the past five years, we’ve researched popular litter boxes from major online retailers, selecting models to test based on criteria provided by the experts we consulted. Freelance reporter Shoshi Parks conducted the initial reporting for this guide and tested litter boxes with her two cats. Since then, freelance reporter Janelle Leeson and two Insider Reviews staffers have tested additional boxes with six more cats. Although we haven’t tested our large box and DIY picks, they meet our experts’ criteria and come from trusted brands. We plan to test them in the next few months.

Each litter box we tested was used for at least one month and evaluated using the methods described below. Unless a box required a specific type of litter to operate effectively, testers used their preferred substrates, including some of the best cat litters and best natural cat litter.

Ease of entry test: We measured the sides of each box and the height of any openings and watched to see whether our cats appeared to have difficulty accessing the boxes. We also observed how our cats responded to each box, noting which they preferred to use more frequently.

Tracking test: For each litter box we tested, we collected the litter tracked onto the floor over three days and then compared the quantity of litter between boxes.

Cleaning test: We cleaned each litter box twice daily, observing how easy it was to access and remove the waste and how much litter stuck to the bottom and sides of the pan. After a month of use, we thoroughly cleaned each box, disposing of the litter and wiping it out completely. We noted how challenging the boxes were to clean and approximately how long it took.

Size test: For this test, we measured the length of each of our cats when standing in a relaxed position from the nose to the base of the tail. We then measured the length of each of the litter box contenders and compared the numbers. We favored larger litter boxes over smaller ones.

We also interviewed seven experts about feline litter box habits and the qualities to look for in a good litter box.

Cat litter box FAQs

What type of litter box do vets recommend?

No single litter box is universally best for every cat. Our experts say most cats prefer open-top litter boxes with good airflow, an easily accessible entrance, clear visibility, and ample space to circle around and dig. However, some cats may prefer enclosed litter boxes that offer more privacy. No matter the design, choose a litter box that is at least 1.5 times the length of your cat from head to base of tail. Providing multiple types of the best cat litter boxes on different floors of your home and in various rooms allows your cat to choose their preferred design and location. A good litter box should also be easy for your cat to enter and exit. “Make sure the sides aren’t too high for your cat,” says Dr. Jamie Richardson, head of veterinary medicine at Small Door Veterinary in New York City. Litter boxes with high sides and ones that are fully enclosed or top-entry may make some cats feel trapped, leading them to avoid it.

Do cats prefer open or hooded litter boxes?

Open-topped litter pans are the most widely accepted boxes by all types of cats. Some cats may feel trapped and be afraid to enter hooded or covered litter boxes, particularly if the interior height is so limited that they need to crouch while eliminating. “If your cat feels vulnerable and unsafe in the litter box, she may not take the time to bury her waste after elimination because she wants to get out of there quickly and prevent being ambushed in the box,” Geller says. In some cases, this may lead to your cat avoiding the box altogether. Additionally, Bell says covered boxes trap odors, intensifying the smell for cats, which can make them reluctant to use the box. Doors on litter box entrances, especially opaque or swinging ones, can make both matters worse.

What type of cat litter do vets recommend?

According to Dr. Liza Cahn, a veterinarian and consultant for Embrace Pet Insurance, most cats tend to prefer litter that is unscented, clumping, and fine-grained, such as clay litter. This type of litter is most similar to sand or dirt, which cats might choose to use in the wild.

Can a litter box be too big?

No. “Most cats won’t mind a box that is a bit larger than they need, provided you keep it very clean,” Richardson says. “The main concern is with litter boxes being too small.”

How many litter boxes do I need?

Sung says a good general rule of thumb for litter boxes is to have one per cat plus an extra. Dr. Karen Sueda, a board-certified veterinary behaviorist, says that in multi-cat households, you may be able to use fewer boxes so long as they’re extra-large sizes and you scoop them at least twice a day. You should also place boxes in different areas of your home.

Where should I put my cat’s litter box?

Ideally, the boxes should be spread out across your home, including on each floor, and placed away from loud, startling appliances like washing machines or dryers. It’s also important to avoid placing litter boxes in busy, high-traffic areas while still keeping them close to where your cat likes to spend time with you. Geller says that a cat’s field of vision matters, too. Rather than tucking a litter box tightly into a corner, pulling it about 12 inches away from walls can improve your cat’s view of their surroundings, helping them feel more secure. Richardson adds that litter boxes should not be placed in the same area where cats are fed. “Cats typically don’t like to go where they eat,” she says.

How often should I clean the litter box?

To keep a cat happily using their litter boxes, our experts recommend scooping them at least once, if not several times, a day. Every four to six weeks, clean the box with unscented dish soap and water.

How frequently does a cat use their litter box?

The typical cat uses the litter box as many as half a dozen times a day, urinating two to four times and defecating once or twice. Some cats may go more or less frequently on average. Cleaning your litter boxes at least once a day will help you monitor for medical or behavioral changes that may indicate a health problem, such as feline lower urinary tract disease (FLUTD).

Why is my cat peeing outside the litter box?

“If your cat is urinating or defecating outside of the litter box, see your vet to rule out medical issues, such as urinary tract infection, cystitis, or arthritis,” Cahn says. If your cat gets a clean bill of health, she recommends taking a closer look at your litter box setup: Do you have the recommended number of boxes placed in different areas — one per cat, plus one extra? Are the boxes spread throughout your home in easily accessible locations? Do you scoop them daily? Cahn also recommends thoroughly cleaning any soiled areas, offering a variety of litter types (both clumping and non-clumping), reducing stressors, increasing enrichment, and finally, consulting a veterinary behaviorist if needed.
