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.

A Quick Look at Our Favorites in 2024

The 8 Best Litter Boxes for Large Cats

1. IRIS Top Entry Cat Litter Box – Best Overall

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.

2. Frisco Open Top Cat Litter Box – Best Value

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.

3. KittyGoHere Senior Cat Litter Box – Premium Choice

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.

4. Van Ness High Sides Cat Litter Box

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.

5. Van Ness Enclosed Cat Litter Box

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.

6. Frisco High Sided Cat Litter Box

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.

7. Booda Dome Cleanstep Litter Box

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.

8. Frisco Flip Top Hooded Cat Litter Box

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.

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.
