Is your cat avoiding her litter box? This, of course, means that she might be peeing everywhere but inside her litter box. If she’s a large cat, it’s quite possible that her current box is too small, which is probably why you’re in the market for a larger one. Not only do you want a litter box that your cat will be comfortable using, but one that will (hopefully) contain the odor and the litter as well.
When it comes to finding just the right litter box, there are many to sort through. That’s why we’ve written reviews on the 10 best litter boxes for large cats that should be big enough for those bigger felines out there. We hope it will make your job easier and you’ll find the perfect one for your cat.

Best Overall
IRIS Top Entry Cat Litter Box
Comes in 4 colors and 2 sizes
Lid has grooves to rid your cat’s paws of excess litter
The IRIS Top Entry cat litter box is our choice for the overall best litter box for large cats. It comes in 4 colors (white, black and gray, gray and white, and white and beige) and is also available in medium and large (which measures 20.5” x 16.2” x 14.6”). Your cat can access this litter box through the entrance on the top, and it gives her complete privacy as it’s fully enclosed. The lid has grooves, which can help knock the excess litter off your cat’s paws, and it’s removable for easy access during cleaning. It also has rubber feet, which help keep the litter box in place.
While the design is attractive given that it’s circular instead of square, this can make using a scoop a little more challenging since there are no corners. Additionally, this litter box will not work well for senior cats with arthritis or who have any kind of problems with jumping.
Overall, we think this is the best litter box for large cats.
Pros
Comes in 4 colors and 2 sizes
The top entrance gives your cat privacy
Lid has grooves to rid your cat’s paws of excess litter
Frisco has given us the best litter box for large cats for the money. This litter box is very inexpensive and comes in gray and navy, and measures 19.8” x 15” x 9.5”. It’s a simple litter box that will give your cat room to do her business with a high back and sides that should help with privacy and keep some of the litter inside. It features a lower front entrance for easy access, and the entire rim is removable for easy cleaning and is recyclable when you’re finished using it.
On the downside, depending on how large your cat is, you might find this litter box a little too small so double-check the measurements. Also, if your cat tends to urinate higher up, there might be some leakage as the rim and base are not airtight.
To conclude, for the money, we think this is the best litter box for large cats.
Pros
Inexpensive
Comes in 2 colors
High back and sides for privacy and keeps the litter inside
Lowered front entrance
The rim is removable for easy cleanup
Cons
It might be too small for some cats
The rim and base are not airtight— possible leakage
The KittyGoHere litter box is our pick for premium choice in litter boxes for larger cats. It comes in 3 colors (beige, green, and lilac) and sizes small and large (which measures 24” x 20” x 5”). This litter box can work for cats of any age, but if you have a large senior cat, this might just fit the bill. The entryway is only 3 inches high, so it will work very well for any cat with mobility challenges. The large size will make it easier for your cat to turn around and do her business.
Unfortunately, while the low sides are great for any cat who needs easy access, they also won’t do a great job at containing the litter that our cats just love to kick out. We also found that the coating of the box allows the urine and litter to stick to it, making cleanup a little more difficult.
Pros
Comes in 3 colors and 2 sizes
Great for senior cats or cats with mobility challenges
The entrance is 3” high, easy to enter
The size will work very well for large cats of any age
Cons
Low sides make it harder for litter to stay inside
The coating on the box makes urine and litter stick
The Van Ness High Sides litter box is an inexpensive litter box with very high sides, and it comes in large (17.5” x 15” x 8.5”) and giant sizes (21.25” x 17.75” x 9”). It is available in blue and features a coating that is resistant to stains and odor and is easily cleaned. The high sides will work quite well for cats that are, shall we say, enthusiastic diggers and any cats that don’t appreciate the enclosed litter boxes. This litter box has also been made with 20% recycled material.
However, the corners are rounded, which might make cleaning with a scooper a little more of a challenge. It also might not be sturdy enough if your cat enjoys perching on the edge of her litter box while she’s doing her business. This litter box for big cats easily earns its spot on our list.
Pros
Inexpensive
Very high sides and
Comes in large and giant sizes
The coating is easy to clean and resistant to odors and stains
Great for cats that enjoy digging and don’t like enclosed spaces
Made with 20% recycled material
Cons
Rounded corners make scooping more difficult
Will not hold your cat’s weight if she likes to perch on the edge
The Van Ness Enclosed litter box is inexpensive and is available in white in large (measuring 19.5” x 15.25” x 17”) and blue in extra-large (measures 21.5” x 17.75” x 18”). It is similar to the Van Ness found in the number four spot but has a lid with a flap. This feature will help to eliminate litter scatter and odor and will give your cat privacy. The coating is stain and odor-resistant and will be easy to clean, and it’s made from 20% recycled content.
On the downside, the flap doesn’t always seem to stay attached. There might be times your cat will knock it off when entering or exiting the litter box. Additionally, we found the clips that attach the lid to the box were flimsy at times and were prone to breaking.
Pros
It is inexpensive and comes in large and extra-large as well as white and blue
Enclosed with a lid and flap to eliminate odor, litter scatter and provides privacy
The coating is easy to clean and stain and odor-resistant
Made with 20% recycled content
Cons
The flap doesn’t always stay attached
Clips that attach the lid to the base were sometimes flimsy
The Frisco High Sided litter box is quite similar to the high-sided Van Ness found at number four, but it’s a little more expensive. It comes in navy blue and a light gray and measures 24” x 18” x 10”, making it one of the larger boxes on our list. Its high sides will keep the litter inside, and it features a lower front entrance making it a little easier for cats to enter and exit. The plastic is durable and quite easy to clean, and the litter box is recyclable when it’s time to replace it.
However, the low front entrance can also be an area where your cat might kick litter out, so while the high walls are effective, the entry might defeat the purpose. It also has rounded corners, which can make scooping and cleaning more of a challenge.
Pros
High sides keep litter in
Comes in 2 colors
High-quality plastic is durable and easy to clean
Recyclable
Cons
Low front entrance could lead to litter scatter
Corners are rounded—cleaning can be more difficult
The Omega Paw Roll’N Clean litter box offers the convenience of rolling the litter box upside down, and the waste is deposited in a pull-out tray. You just need to pull out the tray and toss the waste, and you’re done! There’s a grate that sorts the waste from the clean litter, and it’s all accomplished manually, so you don’t need to use electricity. It’s also a fully contained litter box, so it gives your cat privacy and helps to reduce odor and the litter that gets scattered outside of the box.
However, we found that the grate that does the sifting didn’t always work or stay in place. It also doesn’t always catch the waste in the little drawer, and it was sometimes filled with clean litter. Plus, we also found that the plastic wasn’t as sturdy as we would have preferred. This litter box might break somewhere down the line.
Pros
Rolling the litter box automatically filters the waste
Just pull out the drawer and empty the waste
Doesn’t need electricity
Fully contained— offers privacy and reduces odor and scattered litter
Cons
The grate that sifts out the waste doesn’t always work
Not all of the waste goes into the drawer, sometimes takes in clean litter too
The Booda Dome Cleanstep litter box comes in 3 colors (beige, white, and gray) and offers a large filter. It’s an enclosed dome-shaped “box,” which assists with privacy and helps to minimize odors and scattered litter. It features steps that lead down from the litter area, which will help trap the litter stuck on your cat’s paws and is larger than the average litter box (measurements are 22.5” x 22.5” x 19”). The design not only gives your cat privacy but also keeps all of the waste hidden away.
Unfortunately, the truly large cats will find this litter box for big cats a little too small. The inside design is essentially a crescent moon shape, which cuts down on the usable litter space. We also found that some cats were prone to peeing in the wrong spot and ended up urinating down the stairs instead of inside the box.
Pros
Comes in 3 colors
Dome-shaped and enclosed for privacy and minimizes odors and scattered litter
The Frisco Flip Top Hooded litter box comes in a white and beige color and measures 22.7” x 17.3” x 16.1”. It comes with a lid and a translucent flap for a door that keeps the odor and litter inside the litter box where it belongs. For easy cleanup, it features a top section that can flip up for easy access for quick scooping, or you can remove the entire lid for deeper cleaning. It also includes a charcoal filter for added odor control.
We did have issues with the cat door, however. Some seem to be literally bent out of shape, and others just wouldn’t stay attached and sometimes became stuck. The last thing you’ll want to happen is for your cat to become trapped inside the litter box. The base of the litter box was also not made with very sturdy plastic.
Pros
Fully enclosed with a lid and flap
Features a flip top for quick cleaning
Comes with a charcoal filter
The flap is translucent so you can keep an eye on things
The Catit Large Style cat litter box is attractive as it features white and black tiger stripes on the top and the clasps (and it measures 22.4” x 15.3” x 18.3”). It is another fully enclosed litter box with a see-through flap to help reduce odor and litter scattered outside. This large covered litter box comes with a charcoal filter and features anchors to help hold liners and litter in place.
Unfortunately, the issue is with the flap again. It tends to get stuck, and we found that some cats would become trapped inside the litter box. The clips that attach the lid to the base were not always strong enough to stay closed, causing the lid to detach from the base. We also found that the material for the base seemed rather unsubstantial.
Pros
Attractive white and black tiger stripe accents
Fully enclosed with clear flap, reducing litter scatter and odor
Anchors included that help to hold liners in place
Cons
The flap can become stuck, trapping the cat inside
Plastic a bit on the flimsy side
Clips don’t always stay attached to base
Buyer’s Guide: Picking the Best Litter Box for Large Cats
It seems like it would be a simple thing to do, finding the right litter box for your cat. You’d think you just need to purchase a basic box, and everyone will be happy. But no. That’s not how it works. We all know how finicky cats are, and if you have a large cat, your options are even more limited.
Having said that, there are copious amounts of litter boxes out there, so we’re providing you with a few tips and options to think about while you’re looking at potential litter boxes.
Size
Obviously, since you’re reading these reviews, you’re in the market for a litter box that’s larger than normal. As a general rule, a litter box should be as long as your cat (from the tip of her nose to the very end of her tail) and should be as wide as the length of your cat (just without the extended tail).
If your cat can get in and turn around comfortably, it should be big enough.
Covered or Uncovered
While having an extra large covered litter box might be your preference, it might not be your cat’s. Some cats prefer covered, while others want an open litter box. You might have to try out a few options before you figure out what your cat likes. Finding a good litter box that has high sides and a detachable lid might end up being your best bet if you’re not sure.
Another option to keep in mind is if you also own dogs that seem to enjoy rooting around in your cat’s litter. Having a covered litter box will help to keep the dogs out, but if your cat doesn’t appreciate an enclosed litter box, you’ll need to investigate other ways to prevent the dogs from messing around in your cat’s box.
Number of Litter Boxes
If you own multiple cats, the general rule is that you should have one box for each cat and then one extra. If you have three cats, you’ll need to invest in four litter boxes.
High Sides
The average litter box should have walls that are about 5 to 7 inches high. But if your cat likes to spray or kick the litter all over the place, you might want to opt for walls that are about 8 to 12 inches high.
Keep in mind that if you have a kitten, senior, or any cat with mobility challenges, you’ll want to aim for sides or an entrance that is 2.5 to 3.5 inches high.
Style
A stylish litter box might look nicer than the average box but do keep in mind practicality. If your cat hates the box, you’ll end up with a mess. Automated litter boxes might spook some cats, and door flaps might become stuck or could also scare your cat.
Final Verdict
So, there you have our top 10 litter boxes for large cats! Our pick for the overall best litter boxes for large cats is The IRIS Top Entry for its excellent design. It features a top entrance and grooves to help reduce the litter sticking to your cat’s paws. The best value goes to the Frisco Open Top as a very inexpensive option that will give you a basic litter box with very high sides to keep the litter inside. Lastly, the KittyGoHere Senior litter box is our premium choice pick thanks to its very large size, choice in color, and that it’s a great option for any cat with mobility challenges.
We hope our reviews and guide will help make your choice for a new litter box a little easier. After all, it’s such an essential part of your cat’s life, and yours as well.
Kathryn was a librarian in a previous lifetime and is currently a writer about all things pets. When she was a child, she hoped to work in zoos or with wildlife in some way, thanks to her all-consuming love for animals. Unfortunately, she’s not strong in the sciences, so she fills her days with researching and writing about all kinds of animals and spends time playing with her adorable but terribly naughty tabby cat, Bella. Kathryn is hoping to add to her family in the near future – maybe another cat and a dog.
