    With a long-standing history of over 50 years, Petmate is one of the most reliable cat equipment manufacturers, and this Petmate Booda Clean Step Litter Dome takes first place in our list of the best litter boxes for large cats.

    This plastic dome made in the USA is 50% larger than average litter boxes. Moreover, it has a sleek design with three different colors to fit many home interiors.

    As you might know, cats don’t prefer small spaces to pee. And big cats are more likely to refuse using an undersized box. This spacious cat litter box has the dimensions of 21 x 21 inches to offer your feline friend great comfort. Plus, the 9-inch-wide ramp prevents litter from sticking to your cat’s paws, and the litter pan is 6-inch deep, so it is suitable for cats who love digging.


    The dome lid encloses cats on all sides for the best privacy while preventing the waste from littering around the floor. The removable dome lid with a built-in handle allows you to clean the litter box with ease.

    The best feature of this Petmate Booda Litter Box is the great ability to control odor. It has an air filter with charcoal ingredients attached to the lid’s top to filter out the aroma of the cat’s waste. By replacing the filter piece regularly, you don’t have to worry about bad odors around your house.

    Be sure you’re using the liner and putting the lid on this litter box properly to avoid any urine leakages, but you should always put something underneath your litterbox to protect your flooring anyways. And, if you’re trying to keep a little dog away from your cat’s bathroom business, this isn’t the litterbox for you.

    But those minor details aside, the sleek and round design doesn’t allow odors to get trapped in seams and corners. Hence, when lifting the lid, you will not be overwhelmed by bad smells from the cat’s pee and poo, and your cat will be able to use their toilet without the odors too!

    • Sleek, step design to minimize tracking
    • Easy to clean
    • Great odor control

    If you are looking for an extra-large litter box with high sides, this Nature’s Miracle High-Side might be suitable for it.

    This rectangle high sided litter box is large enough for multi-cat households but can also be used for a single large feline friend. The box is largest at the top then tapers toward the bottom. Combined with its high sides, this can minimize litter scattering to the floor. Although this litter box has a high-sided design, the lower entrance is kitty-friendly.

    The opening in the front of the litter box is about 5 inches from the floor to the lowest part of the opening, which allows both kittens and old cats to step in without any hassle. It would be advised, though, to put a mat down in front of the litter box just in case of any litter dust out of the low point.


    If ease of cleaning a litter box matters to you, this high sided cat litter box might be a great choice. It has a non-stick surface that enables you to spot or wipe clean it. It features antimicrobial protection to inhibit odors and mold and mildew caused by bacteria on the litter box. Moreover, the well-coated plastic prevents odors from being absorbed into the plastic. With this feature, it can withstand extended use without bad smells accumulating day after day.

    This manufacturer, Nature’s Miracle, has other litter boxes that are great too!  We selected this box as our best value litter box for large cats because the unit price can’t be beaten for the utility – but it only comes in bulk packs so it can be a bit expensive upfront. It’s definitely worth calling a few cat-parent friends and going in on a bulk order together.

    • Antimicrobial properties
    • High sides

    For most cat owners, feline friend’s safety is a high priority when choosing a litter box. This well-built iPrimo litter box with its ergonomic design and no sharp details is a great choice for safety. This litter box has all rounded edges to prevent injury.

    Besides, the manufacturer comes up with innovative ideas for an indentation at the center bottom. Thus, the clump wastes will fall on the sides of the litter box and make it easier to scoop them out.

    Last but not least, this litter does not possess any sharp edges. Thus, you don’t have to worry that your cat might experience any harm while using this litter box.

    • Spacious raised-back design

    Some cats have the habit of urinating high in their litter box. As a result, if they have a low-side pan, urine might go directly to the floor. This could lead to major cleaning efforts and even replacing carpet or flooring.

    But what about an extreme high-sided litter box to stop that nightmare once and for all?  This Van Ness high sides cat litter pan can help you with that.

    This Van Ness litter box has the size of 21¼ inches by 17⅝ inches by 9 inches – that is larger than most average litter boxes. Therefore, it can be suitable for a house with more than one cat or a big feline friend that needs a comfortable place for itself.


    With the side walls height up to 9 inches, this litter box will minimize the mess of high-urinating cats. And if your cat loves digging in his litter, you can add more litter into this pan and satisfy the habit with the thicker layer to dig in.

    The most valuable feature of this litter box is the shape. If you have a small room and want to save some space, you should go for a corner, high-side box like this one.

    Buyer’s Guide: Selecting The Best Litter Box For Large Cats

    All cat lovers (and haters) know that cats are a picky type of pet that are often hard to understand. If your cat refuses to use their litter box, it might take you several days to find out what things were wrong with them. Maybe, the answer lies right in the litter box itself. So, how can a box affect the habit of peeing in a cat? Let’s find out now.

    1. Why do big cats need extra-large boxes?

    Cats only use the box that fits them.

    So, no matter what kind of cats you’ve got or how old they are, it is important for them to sit, squat, and turn in their own litter box comfortably. The common rule for the  litter box’s size is about 1.5x the length of the cat’s body without the tail.

    I know that many cat owners are not aware of this rule of thumb. But if you are facing the problem of your cat urinating outside his box, try to buy them a larger box and see the change in their habits.

    Hepper Advanced Bio-Enzyme Pet Stain Odor Eliminator Spray

    Even after the litter is changed you may be left with smells and stains around the house – but with the Hepper Advanced Bio-Enzyme Pet Stain & Odor Eliminator Spray, you can take care of it all. It's our product, and we love it so much, we just have to share it! It permanently removes the very worst smells and stains, and we offer a 100% satisfaction guarantee!

    2. How do you choose the right large litter box?

    So, the question is, how do you choose the right large litter box?

    It might be time-consuming when diving in a large ocean of choice for a cat litter box. So, we will give you some criteria to shorten the process. These are also the criteria we look at when choosing the products for recommendation.

    Let’s take a look.

    Open or enclosed?

    According to research conducted on different cats in their own living environment, half of them prefer open litter boxes. However, trained cats are more likely to have the habit of using enclosed litter boxes.

    So, it totally depends on your cat’s preference. If your current litter box has a privacy lid, you should go for an enclosed option of a large litter box. Otherwise, if your cat doesn’t want to be trapped in a closed space, a no-lid box is a great choice.

    While enclosed litter boxes work well in odor control, open ones make cleaning easier without any lid. Hence, if you want to use a no-lid box, you should scoop out the waste more frequently. And for closed boxes, regular cleaning is required to prevent the buildup of bacteria.


    As we have mentioned above, the suitable length for a litter box must have a length of 1.5 times the cat’s body. For adult cats, you can choose the box with the exact ratio. However, for kittens, you should always go for a larger one since they will grow up and exceed their current length. So, going for the longest pan might be a wise choice.

    High walls


    A common problem of big cats is they often urinate high to the wall of the litter box. So, the crucial factor of a large litter box is high walls to prevent urine leaks to the floor. Moreover, high walls can avoid litter spillover when your cat squats inside the box for a spot.

    A litter box with a hood can offer you even more support with keeping the waste inside for a litter-free floor.

    FAQ & Tips

    1. How big should your cat’s litter box be?

    In general, a litter box should be more than one and a half times the length of the cat. As you might not know, the cat will refuse to use the box if they find the box under-sized. Hence, we strongly recommend the bigger size for the best comfort for your cat.

    2. Do cats prefer covered litter boxes?

    Enclosed litter boxes might be a perfect choice for cat owners but not a good idea for all cats. Many prefer uncovered boxes where they can keep an eye on potential threats to escape (a bit of natural instinct there!). However, if your cat is trained to use an enclosed litter box, it will find staying in a closed box usual.

    3. What is the largest litter box available?

    The largest litter box we could find available in the Omega Paw Self-cleaning litter box, with a roomy pan of 23.5 inches x 21.25 inches x 10.5 inches. However, the small entrance door makes this self-cleaning litter box the right place for a big cat but not two medium-sized ones.

    4. How many litter boxes does a household with multiple cats need?

    The general rule of thumb is one litter box per cat. So, if you have 6 cats, you should have 6 litter boxes. However, you can use a large litter box or heavy plastic mortar mixing trays as a litter box to save you a lot of money.
