A large cat does not need a cute miniature bathroom. My own experience with long-bodied, heavy cats is that a box can look enormous in a product photo and still feel cramped when the cat turns around, digs, or steps out.
The best litter boxes for large cats give a Maine Coon, Savannah, Ragdoll, or hefty domestic cat room to posture and cover waste without sending litter across the floor. I compared eight jumbo and XXL options for interior dimensions, side height, materials, entry access, cleaning, and the practical limits reported by customers.
Large-cat owners repeatedly tell researchers that boxes marketed as jumbo can still be too short for a cat over two feet long. I used the research target of at least 22 by 18 inches as a useful starting point, then gave extra weight to longer pans, higher walls, and open entrances that suit both big cats and older cats with stiff joints.

1. TownTime Extra Large Kitty Litter Box with High Sides — Best Overall
TownTime Extra Large Kitty Litter Box with High Sides, Anti-Splashing, Tool-Free Assembly, Multi Cat, Jumbo (Grey) 24.60″ L x 16.92″ W x 12.99″ H
24.6 x 16.9 x 13 in
Plastic
High-sided open design
Pros
- Roomy interior
- Contains scatter
- Tool-free assembly
Cons
- Needs more litter
- Can retain moisture underneath
The TownTime pan is my first choice for a cat that needs more floor space and a wall high enough to catch enthusiastic digging. Its listed 24.6 by 16.92 by 12.99-inch size gives a large cat a generous open area, while the 13-inch height is especially useful when urine spray or litter scatter is a problem.
Customers describe the construction as sturdy and appreciate the smooth surface when wiping it down. The box also assembles without tools, so I would measure the final floor space before ordering rather than assuming a 13-inch-high pan will work in every litter cabinet.
The main trade-off is capacity: a deep, roomy box takes more litter to reach a useful depth. I also saw reports of moisture collecting underneath, which makes regular inspection and a washable mat worth adding to the setup.
For a 17-pound cat that is long rather than round, the TownTime is a sensible upgrade from a standard open tray. It is less suitable if your cat has limited mobility, because the high sides do not appear to provide the low-entry shape of a senior-specific design.
For whom it is good
This is a strong match for Maine Coon and Savannah households that want an open box with serious side protection. It also works for multi-cat homes where keeping litter inside the pan matters more than a small footprint.
Choose it when a 24-inch-plus length and roughly 13-inch height are more important than lightweight handling. The simple open shape lets a cat see the room while entering and leaving.
For whom it is bad
Skip it for a senior cat that needs a low step-in entrance, unless you add a stable, non-slip ramp. The product does not publish a tested cat weight limit, so I would not treat its plastic construction as proof that it is intended for every cat above 20 pounds.
It is also a less convenient choice for a small room because the high walls and broad pan consume more vertical and floor space than a compact box.
2. Pematar Stainless Steel Cat Litter Box with Lid — Best for Odor Control
Pematar Stainless Steel Cat Litter Box with Lid, 26 x 18 x 12 in
26 x 18 x 12 in
Stainless steel
Lidded high-sided design
Pros
- Resists odors and stains
- Easy to wipe
- Includes mat and scoop
Cons
- Metal edges need checking
- Higher cost
- Dents possible in transit
The Pematar XXXL is the pick for owners who want stainless steel and a covered layout in one 26 by 18 by 12-inch package. Its size is a better fit for a large cat than many standard “jumbo” pans, and the material does not absorb odors in the way plastic can.
Customers repeatedly praise the wipe-clean surface, high sides, litter mat, and included scoop. I would still inspect every folded metal edge before the first use, since a few reviews mention sharp edges or dents received during shipping.
This is a thoughtful option for a multi-cat home, but the lid changes the entry experience. Large cats that dislike enclosed spaces may hesitate, so a gradual transition is more sensible than suddenly replacing a familiar open box.
Stainless steel has another practical advantage: it is easy to rinse after a deep clean and does not depend on a coating to keep the basin from holding smells. The trade-off is that the box feels more like a permanent piece of furniture than a lightweight disposable pan.
For whom it is good
It suits Ragdolls, Maine Coons, and other large breeds that need a 26-inch-long interior and benefit from a lidded, high-sided room. Owners who prioritize odor resistance will get the most value from the stainless steel basin.
The included mat and scoop make the first setup easier. I would place it on a washable floor mat and keep the entry unobstructed so the cat has a clear route in and out.
For whom it is bad
Do not choose it for a cat that refuses covered boxes or feels trapped while eliminating. A metal edge should be smoothed or filed before use if it is not uniformly finished, and shipping damage should be reported rather than worked around.
The higher purchase cost is harder to justify if your cat is happy with an open pan and you do not need a lid for odor or scatter control.
3. IRIS USA XX-Large High Sided Cat Litter Box — Best Value
IRIS USA XX-Large High Sided Cat Litter Box, Scatter Shield, Black
30 x 20 x 14 in
Plastic
14-inch walls
Pros
- Largest listed interior
- High containment
- Open airflow
Cons
- Cracks reported by some
- Large footprint
- Hard-to-reach corners
The IRIS USA XX-Large is the largest open plastic pan in this group at 30 by 20 by 14 inches. That extra length gives a two-foot-long cat room to enter, turn, and dig without immediately touching a side wall, while the 14-inch back and side walls handle scatter well.
It is my best-value choice because the dimensions are unusually generous for the price, and the open top gives good airflow. I like that it is large enough to serve a Maine Coon or a multi-cat household without paying for a stainless steel basin or motorized system.
The tradeoff is footprint. Measure the room and the cat’s route to the box first, because a 30-inch pan can overwhelm a small apartment. Some customers also report cracked deliveries, so inspect the base and corners before adding litter.
The high walls are helpful for cats that stand to urinate, but they can make scooping awkward for a person with back or shoulder pain. A low-entry opening is not listed as a feature, so this is not my first pick for a senior cat unless you add a safe step.
For whom it is good
Choose the IRIS box for a genuinely giant cat or a household that wants one large communal pan. Its 30-inch length and 14-inch height make it one of the strongest open-top choices for containing litter.
It is also a good fit when airflow matters more than privacy. Owners who prefer a simple plastic design will find the smooth interior easier to maintain than a box with many seams.
For whom it is bad
It is a poor fit for tight spaces and for cats that need a 3-to-5-inch step. The box may be difficult to move when filled, and customers have reported some cracked units or edges that complicate scooping.
If your cat is only moderately large and already comfortable in a 25-inch pan, the extra footprint may not be worth it.
4. Catlike Upgrade XXXL Stainless Steel Cat Litter Box — Best Premium Capacity
Catlike Upgrade XXXL Stainless Steel Cat Litter Box 3-Layer Leak-Proof
28 x 20.5 x 14.5 in
152L stainless basin
Tested for 82kg load
Pros
- Huge capacity
- Three-layer leak protection
- Useful accessories
Cons
- Very heavy when filled
- Takes lots of litter
- High cost
The Catlike Upgrade is built for a household that wants capacity first. Its listed 28 by 20.5 by 14.5-inch size and 152-liter volume leave much more room than a typical large plastic pan, while the stainless steel basin is paired with an ABS-reinforced lid.
The three-layer seal is the feature I would care about if urine escaping the pan has been a recurring problem. Customers mention a litter mat, scoop, and charcoal filters, and the 270-degree folding lid gives better access during cleaning than a fully removable cover.
This is a substantial object, not a light tray. Once it contains litter, moving it can be difficult, and owners report needing roughly two 20-pound bags to fill it. I would choose a location with enough clearance to open the lid and clean without dragging the box.
The tested 82-kilogram load rating is reassuring for a large cat, but it is a load rating for the structure rather than a comfort recommendation. A cat still needs enough floor area to turn around, which this box provides in abundance.
For whom it is good
It is best for multiple large cats, a 20-pound-plus Maine Coon, or an owner who dislikes replacing plastic boxes. The leak-resistant layers and stainless surface are meaningful benefits when the box is used every day.
Accessories such as the scoop and filters reduce the number of extra items I would need to buy. I would still keep a dedicated storage tote for clean litter and waste bags.
For whom it is bad
It is not ideal for a small bathroom or for anyone who cannot lift a heavy, filled pan. The large capacity also increases the amount of litter required, so maintenance costs can rise even if the basin lasts longer.
The premium price is a poor value choice for a cat that prefers a small, familiar box. Start with an open alternative if your cat is sensitive to enclosed designs.
5. PINENEST XXXXL Jumbo Stainless Steel Litter Box with Lid — Best for Maine Coons
XXXXL Jumbo Stainless Steel Litter Box with Lid for Maine Coon, 28″ L x 20″ W x 19″ H Extra Large Stainless Steel Cat Litter Box for Big Cat,Multi-Cats Families, Non-Sticky, Anti-Leakage (Gray)
27.56 x 19.69 x 19.32 in
175L capacity
8-inch deep pan
Pros
- Made for giant breeds
- Flip-open door
- Non-stick surface
Cons
- Heavy when filled
- Hinges can fail
- Dents possible in transit
The PINENEST XXXXL is designed for a giant breed rather than simply called jumbo. At 27.56 by 19.69 by 19.32 inches, it offers a 175-liter capacity and an eight-inch-deep litter pan, giving a large Maine Coon space to posture and cover waste.
The 180-degree flip door is a practical touch because I can scoop without removing the entire lid. Customers also like the non-stick stainless surface, included mat and step, and deodorizing compartment for bamboo charcoal bags.
The box is large and heavy, so I would put it in its permanent spot before filling it. A few customers report dented deliveries or broken plastic door hinges; check both the metal panels and hinges before use.
Its size works best for a cat that is long and tall, not just a cat that weighs more. The eight-inch pan helps contain litter, while the lid can provide privacy without making the interior feel as cramped as a small covered box.
For whom it is good
This is the pick for a Maine Coon or Savannah owner who wants a very large, lidded stainless steel option. The flip door and included step make the design more usable than a basic covered tray.
It also suits owners who clean frequently and value a non-stick surface. Place the step where it cannot shift, and inspect the hinges periodically if the cat is heavy or frequently pushes through the door.
For whom it is bad
Do not buy it for a compact room, a cat that dislikes lids, or a person who needs a lightweight pan. The large litter volume and heavy filled weight can make routine changes tiring.
Shipping damage is a real consideration in the customer feedback, so I would photograph the box immediately after delivery and test the door before adding litter.
6. Petmate XL Cat Litter Box — Best Budget Pick
Petmate XL Cat Litter Box, High Capacity, Open, Blue
25.56 x 18.3 x 10.02 in
Plastic
30 lb litter capacity
Pros
- Affordable
- Simple to clean
- Lightweight open design
Cons
- Lower sides
- Litter can escape
- May be tight for giant cats
The Petmate XL is a basic, affordable box for a large cat that does not need the tallest walls. Its 25.56 by 18.3 by 10.02-inch footprint gives more turning room than a standard tray, and the open shape is easy for a cat to enter.
With a listed capacity of up to 30 pounds of litter, it is a practical option for an average large cat or a multi-cat home on a budget. The plastic is lightweight and easy to rinse, which is useful when the box needs to be moved for cleaning.
The main limitation is containment. The sides are lower than the high-sided picks here, so an enthusiastic kicker can send litter onto the floor. I would pair it with a large mat and accept that a giant cat may need more length than this box provides.
It is a strong choice for a cat that already uses an open box and only needs more width. It is less convincing for a cat that sprays high or repeatedly misses the edges.
For whom it is good
Choose the Petmate for a budget-conscious household that values a simple, open pan. Its long review history and easy-clean shape make it a low-risk starting point before investing in a specialized giant-breed design.
It also works when floor space is limited and a 25-inch box is the largest practical fit. Add a washable mat to catch the litter that inevitably leaves a lower-sided tray.
For whom it is bad
It may not be enough for a cat over 20 pounds, a cat longer than 25 inches, or a powerful litter kicker. Customers also report occasional cracked deliveries, so inspect the pan before filling it.
If high-sided containment is the reason you are replacing the current box, look at the IRIS or TownTime instead.
7. Van Ness Pureness Giant High Sides Cat Litter Pan — Best Open-Top Design
Pureness Giant High Sides Cat Litter Pan, Colors may Vary.
20.5 x 17 x 10 in
Polished plastic
High sides
Pros
- Contains scatter
- Resists stains
- Durable and easy to clean
Cons
- Shorter interior
- May be difficult for seniors
- Basic styling
The Van Ness Pureness is a long-running favorite for owners who want a high-sided pan without a lid. Its polished plastic finish is easy to wipe and resists stains and odors, while the high sides help keep litter from being kicked out.
The tradeoff is length: at 20.5 by 17 inches, it is shorter than the other large picks. That may be enough for a broad, medium-large cat, but a Maine Coon that stretches past two feet may need a longer option.
I would use it for a cat that dislikes enclosed boxes and values visibility. The open top makes entry and exit immediate, and the finish has held up well for many owners over years of use.
Older cats may struggle with the 10-inch side height, even though the box is not covered. If your cat has arthritis or reduced hind-leg strength, a lower entry is more important than maximizing wall height.
For whom it is good
It suits an open-top household that wants durable plastic, simple maintenance, and better scatter control than a basic tray. The polished surface is a welcome feature when odors or stains are a concern.
It is also a sensible size for a cat that is heavy but not especially long. Place it on a non-slip mat so the cat feels stable stepping over the high sides.
For whom it is bad
Measure your cat before choosing it because the 20.5-inch length is the weakest specification in this roundup for a giant breed. A senior cat may need a lower step, and the basic design offers no built-in odor filter.
For a 20-pound-plus cat, I would favor a longer 26-to-30-inch model instead.
8. So Phresh Scatter Shield High-Back Litter Box — Best Recycled-Plastic Pick
So Phresh by Petco Scatter Shield High-Back Litter Box Charcoal X-Large 24″ L X 18″ W X 10″ H
24 x 18 x 24 in
50% recycled plastic
High-back shield
Pros
- Contains scatter
- Easy step-in entrance
- Recycled material
Cons
- Front litter escape
- Not for aggressive kickers
- Extra mat may help
The So Phresh Scatter Shield focuses on the problem owners mention most after size: litter thrown over the back. Its 24 by 18-inch base and 24-inch high-back design create a taller rear wall, while the open front keeps the box accessible and airy.
The step-in entrance is easy for cats of different ages, and the material is made from 50% recycled plastic. Customers find the roomy interior comfortable and the price sensible for a large-cat upgrade.
The front is not a complete shield, so litter can still escape toward the room. An aggressive kicker may need a covered box or a second mat rather than assuming the high back solves every angle of scatter.
This design is a good compromise for a cat that wants an open box but needs more rear protection. It is less suitable for a cat that stands and sprays beyond the front edge, because the tall protection is concentrated at the back.
For whom it is good
Choose it for an owner who prefers recycled plastic and needs a high back without a lid. The low step and open visibility are helpful for cats that dislike covered spaces or need easy entry.
It is a good fit for a large cat that kicks litter backward more than forward. A washable mat in front will catch the smaller amount that leaves through the lower front.
For whom it is bad
Do not expect it to contain every scatter pattern; the front remains exposed. It is also not the best pick for a cat that needs a 26-inch or longer turning area, since the listed base is 24 inches long.
If urine spray is the primary issue, choose a lidded or taller-sided design and introduce it gradually.
Buying Guide: How to Choose the Best Litter Box for a Large Cat?
Measure the cat and the room before choosing a pan
Start with the research baseline of at least 22 by 18 inches, then measure your cat from nose to base of tail. A cat that is over two feet long needs more than 25 inches, which is why the IRIS and PINENEST are more convincing than boxes that stop around 20 to 24 inches.
Also measure the narrowest doorway, cabinet opening, and path to the cleaning area. A box can be large enough for the cat and still be impossible to move once it contains litter.
Prioritize high sides only when the cat can enter safely
High sides between roughly 8 and 14 inches help contain scatter and urine spray, but a senior cat needs a 3-to-5-inch entry or a stable step. The best design balances containment with a route that does not make the cat jump.
I would not choose a 14-inch wall simply because it looks more protective. Test the entry with the cat, keep the surface dry, and add a non-slip step if the sides are too high.
Choose open, covered, or lidded based on behavior
Open boxes offer visibility, airflow, and easy entry, which is helpful for large cats that dislike enclosed spaces. Covered and lidded boxes can reduce scatter and contain odors, but a cat must be comfortable turning around and exiting without feeling trapped.
Community discussions repeatedly mention cats refusing covered boxes because they cannot see the room. Keep the current box during a transition, place the new box beside it, and remove it only after the cat uses the new one consistently.
Compare stainless steel with plastic
Stainless steel resists odor absorption and stains and is easy to wipe, but it costs more and can show dents or sharp edge issues. Plastic is lighter, less expensive, and easier to replace, though it may retain smells and can crack during shipping.
A polished plastic box is a practical choice for a simple setup. A stainless basin makes more sense when odor control, long-term cleaning, or a multi-cat household is the priority.
Check capacity and real weight limits
A litter capacity of 30 pounds is not the same as a cat-weight rating. Catlike is the clearest example here: it lists a 152-liter capacity and an 82-kilogram tested load, while several products do not publish a tested cat limit at all.
Do not use litter capacity as proof that a pan will hold a 25-pound cat comfortably. Length, turning room, side height, and the stability of the base all matter alongside any load figure.
Consider a DIY storage tote only when it is safe
Large-cat owners sometimes use a commercial food-storage tote around 26 by 18 by 6 inches because a standard box is too short. I would use that as a last resort or budget project, not as a substitute for checking the cat’s full body length and the tote’s stability.
Never leave sharp cut edges exposed, and make sure the entrance cannot collapse. A tested litter box is safer because its seams, wall height, and cleaning access are designed for repeated use.
Frequently Asked Questions
What litter box is best for very large cats?
A very large cat needs an open or carefully introduced lidded box with at least 22 by 18 inches of interior space, longer if the cat is over two feet, and sides that contain scatter without creating a difficult entry. The IRIS USA XX-Large, PINENEST XXXXL, and Catlike XXXL are strong candidates because they provide the most room.
How big should a litter box be for a large cat?
Use at least 22 by 18 inches as a starting point, then measure the cat from nose to tail base. Cats over two feet long or 20 pounds often do better with a 26-to-30-inch-long pan, while a senior cat needs a low entry even when the sides are high.
Do automatic litter boxes work for large cats?
They can work when the opening and interior fit the cat and the sensors remain unobstructed, but large-cat owners should supervise the first uses and check the manufacturer’s weight and size limits. A cat that is too long for the rotating chamber may not use it consistently.
What litter boxes do vets recommend for big cats?
Veterinary advice generally favors a box large enough for the cat to turn around, a stable non-slip surface, easy entry, and straightforward cleaning. High sides help with scatter, but they should not force a senior or arthritic cat to climb over a high wall.
Are high-sided litter boxes better for large cats?
High-sided boxes are better for containing litter and urine spray, but they are not automatically better for every large cat. Pair high walls with a low entrance or stable step, and watch for signs that the cat hesitates, balances awkwardly, or eliminates beside the box.
Conclusion: The Best Litter Box for Your Large Cat in 2026
For most large cats, the IRIS USA XX-Large is the best balance of room, containment, and value. The TownTime is a close all-around alternative when a high-sided open pan is the priority, while the PINENEST and Catlike make more sense for giant breeds that need a huge lidded or stainless interior.
Measure your cat, measure the room, and choose an entry the cat can use comfortably. A box that fits a Maine Coon’s body, contains scatter, and stays easy to clean is a better purchase than a feature-rich box the cat refuses.
