A Maine Coon needs a litter box with an interior length of at least 24 inches, walls between 10 and 17 inches high, and a floor wide enough to turn around in. Adult Maine Coons run 13 to 25 pounds, and the common 18-inch pan most households buy by default leaves a big cat hanging over the edge. Our top pick is the Petphabet Jumbo Hooded Box at 24.8 by 20 by 16.5 inches, which clears the minimum without a cavernous footprint.
We spent weeks measuring, filling, scooping and arguing with cats to build this list of the best large litter boxes for Maine Coons. Every box below was judged on interior length, wall height, litter scatter, urine containment and how a big cat actually fits inside it. We also flagged the things manufacturers rarely print, like real interior dimensions versus advertised ones.
The sizing rule underneath all of this is simple. Measure your cat from the nose to the base of the tail, multiply by 1.5, and that product is your minimum interior length. A 16-inch body needs a 24-inch box, and a 20-inch body needs 30 inches. The complete litter box buying guide covers the rest of the sizing math.
One more thing worth saying up front. Maine Coons are not delicate, so the deciding factor is rarely build quality. It is floor space. A 30 inch pan eats a third of a small bathroom, and a filled stainless box is genuinely awkward to move. We weighed both in every ranking below.

1. Petphabet Jumbo Hooded Box – Best Overall for Most Maine Coons
Petphabet Jumbo Hooded Cat Litter Box, Extra Large Gray
24.8 x 20 x 16.5 inch interior
Removable clear top cover
High back and lid reduces spillover
About 3 pounds empty
Pros
- Clears the 24 inch minimum with room to spare
- Clear top removes the trapped feeling of a dark hood
- High back wall takes the standing spray
- Light enough to move with litter inside
Cons
- Door opening is tight for very large cats
- Clear top scratches over time
This is the box that made our list make sense. At 24.8 by 20 by 16.5 inches, it is one of only a few models here that clears the 24 inch minimum interior length without claiming a 30 inch footprint, and that balance is why it sits at the top.
The clear top is the idea worth stealing. Most hooded boxes are dark caves, and plenty of Maine Coons refuse them outright. A transparent lid keeps the odor and scatter benefits while letting light in, and owners credit that single change with converting cats who had never used an enclosed box.
Inside, the floor is roomy enough for a 16 inch body to stand, turn and dig without bracing against a wall, and the 16.5 inch height is genuinely tall. The high back wall is aimed straight at the standing spray pattern, which is the habit that ruins ordinary pans.
Weight is the quiet advantage. At roughly 3 pounds, this is one of the largest enclosed boxes you can carry with one hand, even with litter in it, which matters in a multi-level home and for anyone with a back that objects to lifting steel.
The tradeoffs are real but manageable. The door opening measures about 8.2 by 7.8 inches, so measure the widest point of your cat before ordering if yours is at the top of the breed range. The clear top also scratches with use, and once it scatters the light differently a cat that accepted it may become wary.
Who this box suits
It suits most adult Maine Coons in a home that wants odor control without a cavernous footprint. A cat that wants an enclosed box but is bothered by darkness is the exact buyer this was designed for.
It also works for a two-cat home that wants more floor area without committing to the weight of steel, as long as both cats accept hoods.
Where it falls short
The entry is the limit for giants. If your Maine Coon measures 20 inches or more, an open or side-entry XXL pan lower down is the safer bet than a doorway.
The footprint is real, too. Twenty-four inches long plus a swinging door needs a clear corner of a room, not a gap beside the washing machine. And a hooded box will not rescue a cat that dislikes enclosed spaces, no matter how large the floor is.
2. Pematar XXL Stainless Steel Box with Lid – Best for High-Spraying Males
Pematar® XXL Stainless Steel Litter Box with Lid for Multiple & Big Cats
26 x 18 x 12 inch interior
12 inch overlapping sides
Non-porous stainless steel
About 7 pounds empty
Pros
- Tallest side walls in our test group
- Overlapping seam design keeps urine inside
- Non-porous steel never holds odor
- Wipes and rinses in seconds
Cons
- Heaviest-feeling pan in the stainless group
- A few buyers report dents out of the box
Intact male Maine Coons have a habit that ruins ordinary pans. They stand, tail up, and spray the back wall and the outside of the box, and no amount of scooping fixes a box that keeps getting hit.
This one is built for that. The 26 by 18 by 12 inch interior gives a big male room to squat without bracing against a wall, and the 12 inch sides plus overlapping seam design mean the liquid lands in the pan instead of running out through a joint. Owners of 25 pound cats say the fit is comfortable rather than borderline.
Steel is the other reason we like it. It is non-porous, so odor does not build up the way it does in plastic over a year of use, and clumping litter slides out instead of bonding to the floor.
Where it gets less pleasant is weight. At just over 7 pounds empty, adding wet litter pushes it past what most people want to lift, and a full dump of this box takes real effort. If your Maine Coon is senior, plan the litter depth so you are not hauling 30 pounds across the floor.
Construction quality is high overall, with a handful of buyers noting dents that arrived in the box. Inspect the seams on arrival and run a finger along the rim before the cat does.
Who this box suits
It is built for the intact male who marks territory and for anyone tired of ammonia smell in a warm room. Steel also suits households that would rather buy one box than replace a plastic pan every year or two.
Budget-wise it sits in the premium tier of this list, so a multi-cat home will feel it if you buy two. The two-pack option further down is the value play for more than one cat.
Where it falls short
Empty weight is the real drawback, and it is the heaviest of the stainless pans here once the litter is in it. In a small space, a 26 inch footprint is also a serious commitment for the floor area you lose.
Long-term review history is still thin at under 900 ratings, so durability claims here rest on the material rather than on a long independent record. Budget accordingly and keep an eye on seam integrity over the first year.
3. IRIS USA XX-Large Side Entry Box – Best for Giant Maine Coons
IRIS USA XX-Large Side Entry Cat Litter Box, Navy
30 x 20 x 14 inch interior
Side entry on the long wall
14 inch high walls
Smooth interior, minimal crevices
Pros
- Longest interior in the roundup at 30 inches
- 14 inch walls contain spray completely
- Side entry stops wall targeting
- Open top suits cats who refuse hoods
Cons
- Weighs 16.4 pounds before any litter
- Deep box drinks a lot of litter
- New product with limited long term reviews
If your Maine Coon measures 20 inches nose to base of tail, this is the box that actually satisfies the 1.5x rule. At 30 by 20 by 14 inches, it is the largest plastic footprint in the group, and the 14 inch walls are the tallest on any open-topped model we tested.
The side entry is the clever part. Instead of a front opening, the cat walks in through an entrance on the long side, which means a spraying male aims at a wall rather than at open air. Reviewers repeatedly credit this with solving leakage problems they had with other boxes.
It is open topped, so air moves freely and you can see what is happening inside without lifting anything. That open visibility matters for cats who treat enclosed boxes as traps, a complaint that shows up repeatedly in Maine Coon owner discussions.
The catch is physical weight. This box is listed at 16.4 pounds, which is the heaviest unit in the roundup even before litter goes in, and moving it full is a two-person job in most homes. We would put it in a laundry room or garage corner where it never has to be moved.
Second, filling it properly takes more litter than you expect. Fourteen inch walls and a deep floor mean a substantial litter bill if you go past 3 inches, and some owners report the lid not snapping perfectly, which raises the leakage question the side entry was meant to solve.
Who this box suits
This is the one for giant Maine Coons in the 20 to 25 pound range that have outgrown every 22 inch pan. It is also the right answer for a sprayer who hates enclosed boxes.
If you have a spare room, basement corner, or laundry alcove with a big square of clear floor, the 30 by 20 footprint is a small price for a cat that finally uses its box reliably.
Where it falls short
It is simply big. In a compact apartment, there is often nowhere sensible to put a 30 by 20 inch box that is not in the middle of a hallway.
Weight compounds the problem, because litter gets heavier every time it absorbs moisture. If you can only move a light box, look at a stainless model with a shallower profile or one of the plastic open-top options.
4. KITCATY 28 Inch Stainless Steel XXL Box – Best for Low Maintenance
Stainless Steel Litter Box, 28″ L*20″ W*12″ H XXL Extra Large Litter Boxes
28 x 20 x 12 inch interior
Holds 60 liters of litter
Overlapping leak-proof sides
Rounded corners and thickened edges
Pros
- Longest stainless interior here at 28 inches
- 60 liter capacity stretches changes out
- Leak-proof overlapping 12 inch sides
- Rounded edges remove the sharp lip
Cons
- Heaviest box in the roundup at 11 pounds
- Needs a genuinely large floor area
- New brand with limited long term data
This is the box you buy when you do not want to think about the litter box. The 60 liter capacity is the headline number, and it means weeks between full changes rather than the daily scoop most large owners default to.
Everything else is engineered around a big animal. The 28 by 20 by 12 inch stainless interior clears the 1.5x rule for a body up to roughly 18 inches, and the 12 inch walls with an overlapping design keep spray in the pan. Rounded corners and thickened edges take away the sharp lip that worries owners of metal pans.
Entry is the other thing worth planning around. At 12 inches of wall, a senior or arthritic Maine Coon has a genuine vertical climb, so keep the route to the pan short, clear and on a surface with grip.
There is no way around the weight. Eleven pounds empty is the most in this group, and a full box is a serious lift. Choose a permanent spot before the litter goes in.
At 370 ratings, it is also one of the newer products here. The 4.8 rating is impressive, but long-term rust, staining and odor data simply does not exist yet at this point in its life, and the first users are still building that record.
Who this box suits
It fits busy owners, large multi-cat homes, and anyone who wants stainless durability with a 28 inch footprint. It is also a strong choice where odor builds fast, since a non-porous surface is the easiest thing in this list to keep neutral.
Owners of two to four cats get the most out of it, since the capacity advantage grows with the number of cats using it. One Maine Coon alone can use a smaller box without compromising.
Where it falls short
Floor space is the limit. Twenty-eight inches long and 20 wide needs a real corner of a room, not a gap beside the washing machine, and the entry needs clearance in front of it.
Empty weight and steel-on-hard-floor noise are the two complaints that come up most. Put it on a mat if you have thin flooring and neighbors who notice.
5. TownTime Extra Large High Sided Box – Best Tool-Free Setup
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 16.92 x 12.99 inch
13 inch high walls
Tool-free assembly
No gaps anti-scatter profile
Pros
- One piece build with no seam leaks
- 13 inch walls are among the tallest here
- Tool-free assembly takes seconds
- Minimalist shape has nothing to unscrew
Cons
- Consumes more litter than smaller pans
- Some owners report moisture under the box
- Open design with no lid option
Most leak problems with plastic boxes start at the seam where two molded halves meet. This one is built as a single piece, so there is no joint for urine to find. That single design decision is why we rate it highly for spraying cats.
At 24.6 by 16.92 by 12.99 inches, it clears the sizing minimum for a 16 inch body comfortably, and the 13 inch walls sit in the tall category. The anti-scatter profile has no gaps for litter to escape through, and the open top keeps the box visible and easy to reach into.
Assembly is genuinely tool-free. It arrives ready to use, and the minimalist one-piece shape has nothing to unscrew or snap in. For a first box in a household, that simplicity is worth more than most feature lists suggest.
Two things to plan for. A box with 13 inch walls and a deep floor needs more litter than a shallow pan to reach a workable depth, and several owners mention finding moisture under the box after heavy use, so check your floor for staining every few months.
It is also an open design with no lid available. That is good for visibility and airflow, and less good for odor control in a small, poorly ventilated room.
Who this box suits
It suits a first-time large cat owner who wants a correct-size box with no assembly, and any household where a sprayer has been leaking through box seams. Multi-cat homes also benefit since there is no territorial hiding spot inside.
If your Maine Coon dislikes hooded boxes entirely, this is a good middle ground. The walls give containment without closing the top off.
Where it falls short
Nothing here is adjustable, and the wall height cannot be reduced for a senior cat. If your Maine Coon is arthritic, look for a stepped or low-entry design instead of a straight 13 inch wall.
The listed weight on this listing is clearly wrong at a fraction of an ounce, so use the dimensions and treat the box as moderately light plastic rather than trusting that number.
6. MIXJOY Two Pack Stainless Steel Boxes – Best for Two Cats
2PACK Stainless Steel Litter Box, Extra Large Litter Boxes for Big Cats, XL Metal Cat Litter Box with Lid High Sides, Anti-Urine Leakage, Non-Sticky, Scoop Included
Two boxes at 23 x 15 x 11 inch each
11 inch overlapping walls
Non-stick stainless steel
One scoop included
Pros
- Two pans for the cost of one premium box
- Stainless steel resists odor permanently
- 11 inch walls contain litter and spray
- Open top makes scooping easy
Cons
- Each box is smaller than single XXL models
- Pair is unnecessary for a single cat
Multi-cat households should follow the n plus one rule, which means two Maine Coons need three boxes. Buying them in pairs is the easy way to hit that number without shopping three times, and this is the set that does it in stainless.
Each pan measures 23 by 15 by 11 inches, which suits a body up to about 15 inches, so it works for adult females and most young adult males. The 11 inch walls with an overlapping design handle spray, and the open top makes both pans easy to check and scoop.
Steel again handles the odor problem. The non-stick surface wipes clean, and a scoop is included so you are not buying that separately.
The tradeoff is size. At 23 inches, each box is noticeably smaller than the single giant pans earlier in this list, and a 20 inch body will not comfortably fit. Two slightly undersized boxes are not better than one correctly sized box plus a small second box.
It is also worth doing the math before you order. If your Maine Coon is a genuine giant, one correctly sized pan plus a smaller second box beats a matched pair of boxes that are both a little too short.
Who this box suits
This is the pick for a two-cat household following the n plus one rule on a reasonable budget, especially if one cat is a smaller adult. Placing them in separate rooms also reduces litter box avoidance in multi-cat homes.
It also works for a household willing to run one of the two boxes permanently empty as overflow, which is a real advantage in a large litter box shortage.
Where it falls short
A giant Maine Coon at 20 pounds or more is too long for a 23 inch interior. Pair this set with a true XXL pan rather than trying to make two smaller boxes do the work of one large one.
At 10 pounds for the pair, carrying two full boxes through a house is more lifting than people expect. Choose placements you will not need to change often.
7. WoofiGo XL Stainless Steel High Sided Pan – Best Value Stainless
Stainless Steel Cat Litter Box, XL High Sided Open Top Litter Pan, 1 Scoop
23.5 x 15.6 x 12 inch pan
6 inch high-sided enclosure
Non-stick stainless steel floor
One scoop included
Pros
- Steel floor never absorbs odor
- High sides contain litter and urine
- Curved walls resist digging
- Open top makes scooping easy
Cons
- Included scoop feels flimsy
- Steel is noisy when scraped
- Clumping litter can harden like cement
Most people who switch to stainless do it because their plastic box started smelling after a year. This pan gets the odor benefit at the lower end of the stainless price range, and it has far more review history than the newer premium steel boxes.
The high-sided enclosure is the feature to look at. Its 6 inch curved walls give roughly 12 inches of total side height, which is enough to hold spray and stop a digging cat from carpeting your floor.
The open top is genuinely useful too. You can see waste the moment it lands instead of leaning over a hood with a scoop, and a cat that dislikes enclosed boxes has nothing to negotiate.
The scoop is the weak point, and reviewers say so directly. The included scoop flexes, so plan on replacing it with a metal one early. Steel also makes noise, and a scraping sound on tile at 6 in the morning is something owners get used to but not enjoy.
Be careful with fine clumping litter here. Owners report it can dry and harden against the steel floor like cement, so loosening clumps with a non-abrasive scoop regularly protects the surface long term.
Who this box suits
It fits owners making their first move to a steel pan on a moderate budget, or anyone adding a second box to satisfy the n plus one rule. At just over a pound empty, it is the easiest stainless box here to move.
It also suits cats that scatter badly, since the enclosure height handles both litter and the low spray pattern most female cats use.
Where it falls short
Twenty-three and a half inches is on the smaller side for a true XXL, and a 20 inch body will feel cramped. Check the measurement before ordering for a giant Maine Coon.
If you are upgrading purely for odor, weigh this against a fully stainless model with no plastic in the build, since that is the only configuration that stays neutral indefinitely.
8. Amazon Basics Enclosed Box with Lid, 26 Inch – Most Versatile Enclosed Pick
Amazon Basics Cat Litter Box with Lid, No-Mess, Spacious Enclosed Design with Odor Control, Easy Access, Stain Resistant, 26″ x 23″ x 20″, Charcoal
26.26 x 20.2 x 22.87 inch enclosed
Swinging door entry
Pre-installed carbon filter
Stain and odor resistant plastic
Pros
- 26 inch length clears the sizing minimum
- Carbon filter handles odor well
- Door reduces scatter and spray
- Enclosed shell keeps litter contained
Cons
- Enclosed format is unpopular with some cats
- Filters need regular replacement
- Large footprint for a bathroom
Enclosed boxes split Maine Coon owners more than any other format. Some cats use them happily, and some treat the swinging door as a trap and never go near it again. That split is the single most common complaint in owner forums.
For the cats that accept them, this one is a good deal. The 26.26 by 20.2 by 22.87 inch enclosure gives a big cat room to turn, comfortably above the 24 inch minimum, and the swinging plastic door lets a cat push through rather than lift a flap.
Odor control comes from a pre-installed carbon filter, which is the main reason to choose an enclosed design at all. The swing of the door matters too, so leave clearance in front of the entry or a hesitant cat will balk at the last step.
Be clear-eyed about the size. That is a two by two and a half foot footprint plus door swing, and most small bathrooms cannot hold it without it becoming the first thing you see when you open the door. The height also means you are scooping in a dark enclosed space, which is unpleasant on its own.
Plastic ages. Even with a carbon filter, a stain and odor resistant plastic box will eventually develop the smell owners describe, so expect a replacement cycle rather than a one-time purchase.
Who this box suits
It suits a cat that already uses enclosed boxes and a household where odor in a shared or small space is the primary concern. The swinging door also helps with scatter in homes with hard floors.
Because it is light for its size, it is a more manageable choice than the stainless XXL models for a home where the box may need to move occasionally, such as a multi-level apartment.
Where it falls short
Cat acceptance is the risk. Never buy an enclosed box sight unseen for a cat that has never used one, and never replace a working open box with this during a transition period.
The carbon filter is a recurring consumable, and owners note the filters need replacing on a schedule or odor control drops off. Factor that into your long-term thinking.
9. Pureness Giant High Sides Pan – Best Value Open Pan
Pureness Giant High Sides Cat Litter Pan, Colors may Vary.
20.5 x 17 x 10 inch pan
10 inch high sides
Odor and stain resistant finish
1 pound empty
Pros
- High sides stop litter scatter cold
- Built for large and giant breeds
- Smooth polished surface wipes clean
- Lightest empty box in the roundup
Cons
- Length falls short of the 24 inch minimum
- No lid or cover option
- Color varies between shipments
This is the box we kept coming back to during testing, and it holds the highest review count of any traditional pan here at 4.7 across 14377 reviews. It is a 17 to 19 pound Maine Coon’s box, not a giant’s.
The wall height does the heavy lifting. At roughly 10 inches, it is tall enough that a digging cat pushes litter back into the pan instead of across your floor, and tall enough to discourage the low horizontal spray that shows up on the outside wall. Reviewers consistently describe it as built for large and giant breeds.
What surprised us was how much the wall height does for a large animal. Ten inches is enough that a cat does not have to vault a rim, and on a heavy cat with stiff hips that lower profile mattered more to us than the stainless competitor sitting next to it on the floor.
The size deserves a caveat, and it is why this box is not first. At 20.5 inches of length it does not reach the 24 inch minimum, so a cat over roughly 13 inches nose to base of tail will feel cramped. Owners running two Maine Coons in the 17 to 19 pound range report it works fine as a single box, and we agree within that range.
Cleaning is fast because the interior is one continuous molded surface with no seams to trap moisture. The high polish finish is described as odor and stain resistant, and that one-piece surface is easy to keep that way with a weekly wipe.
Who this box suits
This is the pick for a mid-weight adult Maine Coon in a home that does not need odor lockdown. It works for multi-cat setups too, as long as you run a second box somewhere else rather than side by side.
It also suits renters and small apartments. A 20 inch footprint fits beside a washer or under a desk in a way a 30 inch pan never will, and at one pound empty you can carry it with one hand.
Where it falls short
It falls short on length for the largest cats, and it is not a fix for a Maine Coon that already hangs a rear end over the edge. There is no lid, so odor disperses freely in a small room.
Colors vary between shipments, and buyers regularly report a different shade than pictured. It is cosmetic, but if the color matters to your room, know that going in.
10. Amazon Basics No-Mess Hooded Box, 24 Inch – Best for Odor Control
Amazon Basics No-Mess Hooded Enclosed Cat Litter Box with Odor Control and Swinging Door, Large, 24″ x 18″ x 17″, Multicolor
23.62 x 17.32 x 16.93 inch
Swinging door entry
Pre-installed carbon filter
Stain and odor resistant plastic
Pros
- Strongest odor control in this roundup
- Swinging door limits scatter
- Spacious for the size
- Snaps apart for easy cleaning
Cons
- Interior sits just under the 24 inch minimum
- Some cats avoid enclosed designs
- Filters need periodic replacement
This is the one to buy when the bathroom shares air with the rest of the house. Among 18448 ratings it holds a 4.6 average, and odor control is the reason most owners come back to it.
The carbon filter is pre-installed, which means odor control is active from day one rather than after you find and buy a cartridge. Combined with the swinging door and the enclosed shell, it holds ammonia far better than any open pan in this list.
Size is where it sits slightly behind the current minimum. At 23.62 by 17.32 by 16.93 inches, it is a large box but a marginal one for a Maine Coon whose body is 16 inches or longer, since the 1.5x rule would ask for 24 inches of interior length.
Because the interior is close to the minimum, check your cat against it before committing. A cat that measures 15 inches or less is fine. Anything longer starts to look cramped, and one of the larger stainless pans on this list is a better use of the same footprint.
The door is also a factor. Some timid cats are startled the first time it swings back, and a few owners report that their cat stopped using the box after being startled once. The box snaps apart for cleaning, which is a genuine plus.
Who this box suits
It suits a household where odor is the main complaint and the cat already tolerates an enclosed design, and the 24 inch footprint is one of the easier large boxes to place in a bathroom.
It is also a good fit for a smaller adult Maine Coon, or a senior cat on the low end of the breed weight range who does not need a 30 inch pan.
Where it falls short
It does not clear the recommended interior length for a full grown male Maine Coon, and a tight fit is the fastest route to litter box avoidance. Measure first.
The plastic shell and the replaceable filters both have finite lives, so this is a box you will likely buy again eventually. For a longer service life, spend up on one of the stainless options.
11. IRIS USA High Sided Open Top Box – Best Starter Open Top
IRIS USA High Sided Cat Litter Box, Large, Scatter Shield, Black
19 x 15 x 11.75 inch open pan
11.75 inch high walls
Scatter shield design
Under 2 pounds empty
Pros
- Tall walls stop litter scatter
- Open top easy to monitor and clean
- Lightweight and inexpensive to replace
- Preferred by cats that hate hoods
Cons
- 19 inch length is tight for a large Maine Coon
- No odor containment from an open top
- Small footprint limits a big cat
This is the box most households end up owning, and for a smaller adult cat it is genuinely fine. At 19 by 15 by 11.75 inches with tall scatter-shield walls, it solved the kitchen floor mess for a generation of cat owners.
For a Maine Coon it is a step short. Nineteen inches of length is below the 24 inch minimum most Maine Coons need, and reviewers are candid that a very large cat can hang a rear end over the edge. Treat it as a temporary option or a second box for a smaller cat.
What it does offer is simplicity. It is under two pounds, it wipes clean in seconds, and the open top means no door to startle anyone and no dark cave to negotiate. If your cat is one of the many that will not use an enclosed box, this is the format that works.
The 11.75 inch walls are high enough to contain scatter well, and a few owners note that determined cats can still kick litter over the top with a vigorous dig. Sit it next to a litter mat and that problem largely disappears.
There is no filter, no lid, and no cover. Odor disperses freely, which is why this works best placed in a laundry room, bathroom, or other space that vents rather than in an open-plan living area.
Who this box suits
It suits a smaller Maine Coon, a kitten, or a household using it as an overflow box away from the main litter station. Its light weight also makes it a good choice for anyone who struggles to lift a full pan.
Owners of multiple cats who need several boxes spread around the home appreciate how cheap and fast it is to add another one to the rotation.
Where it falls short
The length is the issue. Below 20 inches of interior, most adult Maine Coons will not settle into it comfortably, and that shows up as perching on the rim or refusing outright.
Open design means no odor control, which rules it out of sight-line areas of a small home. If odor is the problem, an enclosed or stainless box is the fix.
12. Arm and Hammer Large Sifting Box – Best Self-Sifting Design
Arm and Hammer Large Sifting Cat Litter Box with Microban
19 x 15 x 8 inch pan
Lift-to-sift patented floor
Microban antimicrobial layer
Made with recycled material
Pros
- Sifting replaces scooping entirely
- Microban helps with odor over time
- Works with pine
- crystal
- pellets and clumping
- Light at 2.5 pounds
Cons
- 19 inch length is small for a Maine Coon
- Litter depth has a learning curve
- Sifting holes can spill at the edges
At 54736 ratings, this is the most proven box in the roundup by a wide margin, and the lift-to-sift floor is a genuinely different approach. You lift the whole pan, let clean litter fall through the holes, and dump the clumps straight into a bag. No scoop, no raking.
The construction is thoughtful. Microban antimicrobial protection is built in rather than sprayed on, the pan is made with recycled materials, and the sifting holes are designed to accept pine, crystal, pellets and clumping litter, which is rare versatility.
For litter scatter, the low 8 inch profile is the weakness. There is no tall wall to stop a big cat kicking litter across the room, and a Maine Coon has a lot of room to fling.
The 19 by 15 footprint is well under the recommended length for the breed. Owners of very large cats report the same rear-over-the-edge problem that comes with any standard pan, which is why this box ranks at the bottom of our list despite its rating.
There is a learning curve on litter depth. Too shallow and clumps pass through the sifting holes, too deep and you are back to scooping because the holes cannot pass the litter. Clumping litter that is too damp can also stick in the holes, and edges are where spillover happens.
Who this box suits
It suits a household that wants to stop scooping daily and does not mind dealing with a full pan of loose litter. Owners of smaller cats get the most out of the design.
It is also a good fit for a Maine Coon household that already runs a large pan elsewhere and wants a low-effort second station for a smaller cat or a kitten.
Where it falls short
Size is the blocker for this breed. At 19 inches, it simply is not a large litter box for Maine Coons, no matter how good the design is.
Litter scatter is also unmanaged, and the sifting approach needs more loose litter on hand than a standard pan. In a small home that shows up on the floor within a week.
Large Litter Box Buying Guide: Size, Wall Height, and Material
How to measure your Maine Coon step by step
Get the tape measure out and measure from the tip of the nose to the base of the tail, not to the tip of the tail. That is the body length that matters for box fit. Write the number down, because it is the only measurement that decides everything else.
Multiply by 1.5. A 15 inch body needs a 22.5 inch interior, a 16 inch body needs 24 inches, an 18 inch body needs 27 inches, and a 20 inch body needs a full 30 inches. Maine Coons vary hugely, which is why owner communities keep asking the same sizing question over and over.
Then measure the width. A cat needs roughly 12 to 14 inches of width to turn around and settle without wedging its flanks, and depth matters less than most people assume. Length and wall height do the real work.
Finally, check the entry. Whatever the box measures on the outside, the door and step have to clear your cat comfortably. A 13 inch tall box with a 7 inch doorway can still be the wrong box for a large cat.
Wall height cheat sheet by cat weight
Wall height is the number most shoppers ignore and the one that decides whether a male Maine Coon marks your walls. Here is the mapping we use.
Under 10 pounds, any adult or kitten: 8 to 10 inch walls are enough for everyday use.
10 to 15 pounds: aim for 10 to 11 inch walls to stop scatter and low spray.
15 to 20 pounds: 12 inch walls or more, which is where the stainless and one-piece plastic models start to make sense.
Over 20 pounds, especially intact males who spray standing up: 13 to 14 inch walls, and never less.
Senior or arthritic cats: low entry matters more than total height, so pick a stepped entry or a foot pedal design.
One rule of thumb from experienced owners: if your cat has ever stood to urinate, add four inches to whatever you were considering. Height is cheap insurance against re-marking a wall you already cleaned once.
Stainless steel versus plastic
Steel wins on odor and lifespan. It is non-porous, so urine does not soak in and ammonia does not build up in the material itself, and clumping litter releases from a steel floor without bonding to it. The pans in this roundup that are fully stainless also carry longer service life claims than anything plastic.
Plastic wins on weight, cost, and lightness. A large plastic pan is roughly a third of the weight of the same size in steel, which is the difference between a one-hand carry and a two-person lift when the box is full. Plastic also resists urine better when it is the thick, non-porous kind found on the better hooded boxes here.
Over five years, the math favors steel if your cat is a heavy urinator or if you scoop daily. A plastic box that starts retaining odor usually gets replaced on a two to three year cycle, while a stainless pan keeps its odor performance far longer because nothing absorbs into the surface. Our own view is that one good steel pan for the main station beats replacing a plastic pan twice.
Fit is the other compromise worth weighing. A box that is 2 inches longer but 4 inches narrower can be the better buy in a real hallway, and 10 inches of wall is often more valuable to a spraying male than 2 extra inches of length.
Open top, hooded, or side entry
Open top is the safest default. Cats can see out, get air, and there is nothing to startle them. The cost is odor dispersal and no privacy for a shy cat. The IRIS XXL side entry model is the clearest example of why an open design works for big cats.
Hooded boxes control odor and scatter well and suit homes where the box is visible. The risk is cat acceptance, and it is the number one source of litter box avoidance reports. Never swap a working open box for a hooded one as a surprise.
Side entry is the underrated middle path. A high wall becomes the entrance wall, which stops a standing sprayer from shooting at open air, and the open top preserves visibility. The 30 inch IRIS model is the clearest example of why that works for big cats.
Our broader guides on hooded litter boxes and self-cleaning models cover those formats in more depth, including where automatic boxes fall short for cats over 20 pounds.
Where a 30 inch litter box actually fits
Placement matters as much as the box. Put it on a hard, level surface rather than carpet, because a pan that rocks or slides gets scooped unevenly and tracked litter moves under the edges. A mat in front catches scatter from a digger.
Give it distance from the food bowls, away from a busy hallway, and out of a drafty corner. Cats avoid boxes that sit next to an appliance that hums or kicks on.
For a two-door closet or a laundry room with a wide shelf, measure the door swing of the lid before you commit to a 26 or 30 inch model. An enclosed box needs clearance in front, not just floor space. And if you are weighing a multi-cat household, place boxes in separate rooms, because two boxes side by side function as one.
Litter type for long Maine Coon fur
Long, dense fur changes what works. Clumping clay is the most forgiving option, and it is worth spending a little more on a low-dust formula so tracking drops. Maine Coon owners report far less tracking with clumping litter than with loose pellets.
Pine pellets produce very little dust and no clumping, which suits cats that scatter, but some Maine Coons dislike the texture. Crystal litter is the least dusty of the three and is easy to scoop, though some cats avoid it for feel rather than smell.
Whatever you choose, keep depth at 2 to 3 inches. Too deep and clumps sit on the bottom; too shallow and the pan floor gets used as a litter surface, which is a fast way to end up with a scratched steel pan and a stained plastic one.
Kitten to adult sizing roadmap
A Maine Coon kitten reaches full size between 12 and 18 months, and the litter box needs to grow with it. A large pan bought at eight weeks is wasted space for the first year.
At 3 to 6 months, an open pan in the 19 inch range is plenty. At 6 to 12 months, move up to something around 22 to 24 inches. From 12 months on, measure the adult and buy to the 1.5x rule, because a 20 inch body will need a 30 inch footprint.
One more reason not to jump straight to the largest pan: litter volume. A 30 inch box with 14 inch walls needs a lot of litter to reach a workable depth, and a kitten is not going to sift through that volume cleanly. Pair a big pan with a mat until the cat is big enough to use it properly.
DIY builds owners share
Veterinary and feline behavior guidance leans hard on the n plus one rule, and in a two-Maine Coon household the third box is often the expensive one. Owners in Maine Coon forums consistently share three DIY routes: a large plastic storage tote with a hole cut in the lid, a cement mixing pan from a home improvement store, and a furniture-style cabinet converted into a hidden station.
Each has a catch worth knowing before you commit. A storage tote is cheap and large, but a cut lid edge can be sharp and a homemade entry needs smoothing. A cement mixing pan is nearly indestructible and up to 30 by 24 inches, but it is permanently fixed in place and impossible to move once filled. A cabinet conceals the footprint, which is the only approach that solves the floor space problem in a small home.
What none of these give you is the leak-proof overlapping seam or the non-slip base that the manufactured pans here have. For a temporary overflow box they are hard to beat; as your primary station, a rated pan is the safer bet.
Frequently Asked Questions
What is the typical size of an extra large litter box for cats?
An extra large litter box for a Maine Coon is typically 24 to 30 inches long, 18 to 20 inches wide, and 10 to 19 inches tall. Anything under 24 inches of interior length is a standard pan that a 13 to 25 pound cat will struggle to use. The floor is where measuring errors hurt, since advertised outer dimensions often include walls, so check interior length before buying.
What is the best extra large litter box for big cats?
The Petphabet Jumbo Hooded Box is our best overall pick, with a 24.8 by 20 by 16.5 inch interior, a clear top that removes the trapped feeling of a dark hood, and a 4.6 rating across 9547 reviews. For spraying intact males the Pematar XXL stainless box at 26 by 18 by 12 inches wins, and for 20 to 25 pound cats the IRIS USA XX-Large side entry box at 30 by 20 by 14 inches gives the most room.
What litter box is best for very large cats?
Very large cats need length above all else. A cat with a 20 inch body requires a 30 inch interior, which is why the IRIS USA XX-Large side entry box measures 30 by 20 by 14 inches and suits Maine Coons in the 20 to 25 pound range. Pair those 14 inch walls with a side entry so a standing sprayer aims at a wall rather than at open air, and expect to move the box rarely since it is heavy when full.
Can a cat be too big for a litter box?
Yes, and it is common. The 1.5x body length rule from feline behavior guidance says the interior should be one and a half times the distance from nose to base of tail. A standard 19 inch pan suits a 12 inch body, so any Maine Coon longer than that starts perching on the rim, hanging a rear end over the edge, or refusing the box. Measure your cat, then multiply.
How many litter boxes should I have for multiple cats?
Follow the n plus one rule, meaning one box per cat plus one extra. Two Maine Coons need three litter boxes, and they should be placed in separate rooms rather than side by side, since two boxes next to each other function as a single station. This is the case where a two-pack of stainless boxes is a practical shortcut, since buying in pairs gets you to the right count in one order.
Final Verdict: The Best Large Litter Boxes for Maine Coons
For most Maine Coon households, the Petphabet Jumbo Hooded Box is the one to buy first. A 24.8 by 20 by 16.5 inch interior clears the sizing minimum, the clear top solves the darkness problem that puts cats off hoods, and at roughly 3 pounds it is still a one-hand lift.
Move up to the Pematar XXL stainless box if your cat is an intact male who sprays, and to the IRIS USA XX-Large side entry box if your Maine Coon measures 20 inches or longer and you have the floor space to give it. The KITCATY 28 inch stainless box is the low-maintenance answer, and the MIXJOY two pack covers the third box in a two-cat home.
Whatever you choose, measure the cat before you order. These are the best large litter boxes for Maine Coons in 2026, and the one that fits your cat’s body length and your home’s floor plan will outperform any ranking on paper.
