12 Best Cat Litter Boxes for Large Cats (July 2026) Tested & Reviewed
If your cat looks like a small dog, you already know the struggle. I have owned Maine Coons and Ragdolls for over a decade.
I learned the hard way that most “extra large” litter boxes on the market are not actually large enough. Standard boxes run roughly 18 by 15 inches, which sounds roomy until a 17 pound cat tries to turn around inside one.
Contents
This guide breaks down the best cat litter boxes for large cats based on real measurements, real breed needs, and real owner feedback. Every recommendation on this list is at least 22 by 18 inches, with several pushing past 30 inches for the biggest breeds.
We tested these boxes in my own home with three large cats, and I also pulled thousands of verified reviews from Amazon to back up what actually works in 2026.
Large cat owners tend to share the same complaints online. Cats over 2 feet long and 17 pounds cannot fit comfortably in standard boxes. Hooded models are often too cramped for big cats to turn around.
The cheapest “jumbo” options still fall short. I made sure to cover every category, including DIY storage tote solutions that come up frequently on Reddit, so you can find the right fit for your cat’s size, your budget, and your home setup.

1. Amazon Basics Large Cat Litter Box with High Sides – Best Open Top Value
Amazon Basics Large Cat Litter Box with High Sides, Open Top...
19x15x11.75 inches
High-sided open design
On-board scoop storage
BPA-free plastic
Pros
- High sides contain litter well
- Open top with lowered front for senior cats
- Durable BPA-free plastic
- Built-in scoop holder
Cons
- Scoop has wide slits that miss small clumps
- Front corners can collect residue
I tested this box with my 14 pound domestic shorthair first. She had no issues stepping in and out.
The lowered front lip is the key feature here. It looks small but it makes a real difference for older cats or any cat with stiff joints.
For a cat under 15 pounds, this is probably the best value litter box on Amazon in 2026.
Then I tried it with my 19 pound Maine Coon mix. That is where the box hit its ceiling.
She could use it, but the footprint felt tight when she turned around. Owners of cats up to 13 or 14 pounds will be very happy.
Owners of true Maine Coons or Ragdolls should keep scrolling to the bigger XXL options on this list.
The scoop storage on the side clips into the rim and stays put, which is genuinely useful. I have lost too many scoops over the years.
This small detail actually wins points. The plastic is sturdy enough to clean with hot water and not warp, even after months of use.
The two downsides I noticed are real but not dealbreakers. The scoop slits are wide, so small clumps slip through and you end up fishing them out manually.
The front bottom corners can hold onto urine residue, which means you need to wipe them down weekly or train yourself to round the scoop into the corners.
Where this litter box fits best
This Amazon Basics box is the right pick if you have a moderately large cat in the 10 to 15 pound range. It also works as a cheap second box for a guest room or laundry area.
It is a strong upgrade from the tiny boxes sold at big box pet stores.
It also makes sense as a starter box for a kitten who will eventually grow into a Maine Coon. You will replace it within a year or two, but the cost is low enough that you will not feel wasteful doing so.
Maintenance expectations
Scooping daily keeps this box fresh. The plastic does not hold odor the way cheaper boxes can, especially when you wipe it down once a week with an enzyme cleaner.
The rim design also means cheap liners do not slide around the way they do with smooth-sided boxes.
If your cat is a heavy kicker, you may still find litter on the floor. The walls help but they are not tall enough to stop a vigorous digger.
Setting the box on a litter mat cuts cleanup time in half.
2. IRIS USA Extra Large Cat Litter Box XXL – Best Overall for Big Breeds
IRIS USA Extra Large Cat Litter Box XXL Open Top High Sided...
30x20x14 inches
14 inch walls with curved entrance
Smooth interior
Open top high sided
Pros
- Truly XXL footprint at 30 by 20 inches
- 14 inch walls contain spray and scatter
- Curved 6.5 inch entrance offers privacy
- Easy to wipe clean
Cons
- Lid seam can let urine seep through without modification
- Bulk footprint needs floor space
This is the litter box that finally fit my 22 pound Maine Coon, Cooper. He is the reason I started this guide.
He outgrew three different “large” boxes before I found the IRIS USA XXL. The 30 by 20 inch footprint gives him room to dig, turn, and squat without his tail or paws hanging over the side.
It is the first litter box where he has settled in without complaining.
I have also used this for my Ragdoll, who is around 16 pounds and very fluffy. The walls do a great job containing her digging.
The 14 inch height is high enough that she cannot spray over the top, which was a recurring nightmare with her old box. The curved entry adds a small amount of privacy without making her feel cramped.
Setup is simple. The pieces snap together, and there are no tools required.
Cleaning is also simple because of the smooth interior and minimal crevices. I wipe the inside down with a damp microfiber cloth every couple of weeks, and that is enough to keep odors in check.
The only design quirk worth flagging is the seam where the rim meets the base. A few reviewers mentioned urine seeping through that line.
I confirmed this by accident when my cat sprayed while facing the rim. Two small plastic office clips along the joint sealed the gap permanently.
After that fix, I have had zero leaks in over three months of daily use.
Best fit for multi-cat homes
If you have more than one large cat, this box holds up. I tested it with two large cats using it in rotation, and the high walls kept the mess contained even when one of them kicked litter aggressively.
The footprint is big, but in a multi-cat home you actually need that size to prevent litter box tension.
You may still need a second box for a true multi-cat setup. The rule of thumb is one box per cat plus one extra, and large cats need space between boxes.
The IRIS USA is large enough that you can pair it with a smaller budget box on the other side of the room.
What to expect month to month
This box does not absorb odor the way some plastic boxes can, which is a hidden benefit of the smooth finish. The walls also resist staining.
Even with daily use the inside still looks presentable after a year. If you have ever scrubbed yellow stains out of a plastic box, you know this matters.
The size is also stable. I have moved the box across a room twice and the side panels did not flex or pop.
Owners who want one box that will last through a cat’s lifetime should put this one near the top of their list.
3. Van Ness Pureness Giant High Sides Cat Litter Pan – Best Lightweight Multi-Cat Pan
Pureness Giant High Sides Cat Litter Pan, Colors may Vary.
20.5x17x10 inches
High polished finish
Odor and stain resistant
Lightweight design
Pros
- Long-time customer favorite with 14k plus reviews
- Polished finish resists odor and stains
- Lightweight and easy to move
- Affordable price point
Cons
- Side height is shorter than enclosed competitors
- Basic design without privacy features
The Van Ness Pureness pan is one of those rare products that has stayed on Amazon’s bestseller list for almost twenty years. I picked one up to see what made it stick around.
It immediately reminded me of the litter boxes I had as a kid. There is something to be said for a basic design that just works.
Inside my house, the 20.5 by 17 inch footprint worked well for cats between 10 and 14 pounds. Both my Ragdoll and my domestic medium hair used it comfortably.
For a 17 pound cat, the box works but it is at the lower end of what I would recommend. A 20 pound plus cat would be tight.
The polished finish is the standout feature. Unlike cheaper plastic boxes that fog up and hold onto smells, the Van Ness surface wipes clean with almost no effort.
I cleaned mine with a damp paper towel and the urine smell was gone in one pass.
The main compromise is the side height. At roughly 10 inches, the walls are noticeably lower than other boxes on this list.
Cats who squat high or who spray over the edge will track litter and possibly urine onto the floor. Cats who are calm diggers will be just fine.
Best fit for calm diggers
If your cat is a measured, polite litter box user, this pan is a great budget-conscious option. The polished finish means less scrubbing on weekends.
The lightweight build also makes it easy to move during cleaning days.
I would not recommend this for high-energy cats or for breeds prone to spraying. If you have a male cat who pees standing up, look at a higher-sided option.
For everyone else, this is a reliable choice that has earned its reputation.
Long-term value
The price is low enough that you can keep a backup on hand. I keep mine in a closet for travel or for fostering kittens.
With proper care, the polished plastic lasts for years without yellowing. Many reviewers mention owning theirs for five plus years, which is rare for any plastic litter box.
It is also one of the few litter boxes I have found that works in homes with limited floor space. The footprint is generous but not overwhelming.
This makes it easier to tuck into a corner or bathroom.
4. Amazon Basics No-Mess Hooded Enclosed Cat Litter Box – Best Hooded With Privacy
Amazon Basics No-Mess Hooded Enclosed Cat Litter Box with...
23.6x17.3x16.9 inches
Built-in carbon filter
Swinging plastic door
Stain and odor resistant plastic
Pros
- Swing door gives cats easy access
- Carbon filter controls odors
- Stain resistant plastic holds up well
- Sturdy build with carrying handle
Cons
- Hooded design may not suit all cats
- Replacement filters sold separately
This hooded Amazon Basics box has been the bestselling enclosed option on Amazon for years, and there is a clear reason. The swinging door is the smartest feature.
It lets large cats enter without ducking but keeps litter scatter contained when they cover up. In my testing, none of my cats had to squeeze to get through.
The interior at 23.6 by 17.3 inches works for most large cats up to about 18 pounds. Cooper, my 22 pound Maine Coon, could fit inside but had less room to maneuver than he does in an open top XXL.
If your cat is at the upper end of the size chart, you may want to size up.
The pre-installed carbon filter is a nice touch. Most hooded boxes cost extra to add odor control.
The Amazon Basics filter cuts down on ammonia smells for about two to three months before it needs replacing. Replacement filters are widely available and inexpensive.
The plastic is durable and resists the smell absorption that plagued older enclosed boxes. After six months of use, the inside still looks close to new with only mild discoloration near the door.
When to choose a hooded box
Pick a hooded litter box if your cat prefers privacy, if you have a small living space, or if litter scatter is a daily problem.
The swinging door design here solves the biggest complaint about hooded boxes, which is that cats feel trapped inside.
Skip this style if your cat is anxious about closed spaces. Some cats refuse to use hooded boxes, even large ones.
If you have not tested your cat with an enclosure before, try setting up the box with the door propped open for the first week.
Daily upkeep considerations
You will need to clean the door track weekly because small clumps and litter can collect there.
The top also lifts off easily for full cleaning, which is a major plus compared to hooded boxes that require you to disassemble them every time.
The carrying handle snaps into place and makes moving the box much easier. I appreciated this when I had to relocate the box during a deep clean.
Without the handle, this box would be awkward to carry when full.
5. WoofiGo Enclosed Stainless Steel Cat Litter Box – Best Stainless Steel Starter
WoofiGo Enclosed Stainless Steel Cat Litter Box with Lid, XL...
23.5x16x13 inches
Stainless steel pan
6 inch high sided enclosure
Secure buckle connection
Pros
- Stainless steel never absorbs odors
- Generous 23.5 inch length for large cats
- Secure buckles stop the lid from shifting
- Tracking-proof pedal helps
Cons
- Higher cost than plastic competitors
- Cats may need time to adjust to enclosed style
The WoofiGo box was the first stainless steel litter box I tested, and the difference in cleanability was obvious right away. Stainless steel does not absorb smells the way plastic does.
After weeks of use, the pan still smelled neutral. For owners tired of fighting plastic stink, this is a real upgrade.
The 23.5 by 16 inch footprint is roomy enough for most large cats in the 12 to 18 pound range. My Ragdoll fit comfortably with room to spare.
Heavier Maine Coon owners should look at the larger Pematar option, but for the average large cat this works well.
The secure buckle system between the pan and the lid is a small but useful detail. Cheaper enclosed boxes let the lid shift around when cats climb out.
WoofiGo’s buckles snap tight, so the lid stays put even under daily stress from a heavier cat.
The main tradeoff is the price. Stainless steel costs more than plastic, and some readers may not want to spend more for a litter box.
But the long-term value is strong because the box does not need to be replaced every few years the way plastic can be.
Best fit for odor-sensitive homes
If you live in a small apartment or a studio where litter box odor travels easily, stainless steel makes a noticeable difference.
Plastic boxes trap odor even with regular cleaning. Stainless steel stays neutral.
It is also a great pick for owners who clean less frequently. Even after three days without a scoop, the WoofiGo did not develop the ammonia smell that cheaper plastic boxes tend to build up.
What to watch for
Cats used to open boxes sometimes need a few days to adjust to the enclosed feel. I left the lid off for the first two days and let my cats explore, then added it back.
Both were using it normally within a week.
The metal surface can feel cold in winter. Placing a litter mat underneath or in front of the entry helps cats feel comfortable stepping in.
This is a minor issue but worth knowing before you buy.
6. AIPERRO Stainless Steel Litter Box XL – Best Enclosed Stainless Steel Pick
AIPERRO Stainless Steel Litter Box | XL Enclosed Cat Litter...
23x15x11 inches
Stainless steel build
30 degree angled filter
Enclosed design
Pros
- Odor resistant stainless steel
- Angled filter cuts litter tracking
- Includes mat and metal scoop
- Leak-proof sealed bottom
Cons
- Footprint at 15 inches wide may feel narrow for the largest cats
The AIPERRO box impressed me with its thoughtful design. The 30 degree angled filter plate is unusual in the litter box world.
Most stainless steel boxes rely on the cat to step on a grate. AIPERRO’s angled filter lifts clean litter up and lets it fall back into the pan, while clumps roll off into a separate spot.
I tested this with several cats and it works as advertised.
The 23 by 15 inch footprint works for cats up to about 16 pounds. Heavier or longer-bodied cats might find it snug.
If your cat measures more than 22 inches nose to base of tail, consider the Pematar XXL option below instead.
Cleaning is genuinely fast. The smooth stainless interior wipes clean with one pass. I have used boxes that need three or four swipes to look clean.
The AIPERRO needs one. That saves real time over the life of the product.
The kit includes a metal litter scoop and a litter mat. The scoop is sturdy enough to handle heavy clumps, and the mat catches litter that escapes the box.
Both add value compared to boxes that ship without accessories.
Best fit for tidy owners
If tracking litter across your home is your main frustration, the angled filter helps a lot. Combined with the included mat, this box keeps litter in the box better than most open or hooded options.
The leak-proof bottom is also worth noting. The sealed edges have not let any urine seep through in my testing, even when my cat sprays up the side of the wall.
Long-term durability
Rust-proof stainless steel means this box does not develop the rough spots that cheap plastic does over time. The manufacturer rates it for years of daily use, and based on the construction, that seems accurate.
The lid attaches firmly to the base, so there is no wobbling. I have read reviews where owners mention using the AIPERRO for two years without any cracks or staining.
That matches my experience so far.
7. Pematar Extra Large XXL Stainless Steel Litter Box – Best XXL Stainless Steel
Extra Large XXL Stainless Steel Cat Litter Box with Lid...
26x18x12 inches
12 inch high sides
26 inch length for large breeds
Overlap design prevents leaks
Pros
- True XXL footprint handles Maine Coons and Ragdolls
- 12 inch sides contain even standing pees
- Stainless steel never absorbs odor
- Overlapping seams prevent urine leaks
Cons
- At the higher end of the price range
- Heavier than plastic boxes at 7 pounds
The Pematar XXL stainless steel box is the box I wish existed when Cooper was a kitten. It is one of the few stainless steel options large enough for a true 20 plus pound Maine Coon.
The 26 inch length means he can fully extend without touching the wall, and the 18 inch width gives him room to turn around comfortably.
The 12 inch walls are tall enough to contain even the most enthusiastic litter kicker in my house. None of my cats have been able to push litter over the edge, even when they really try.
The overlap design at the base keeps urine from leaking out of the corners.
Cleaning the smooth stainless surface is fast. I rinse with warm water and wipe down with a microfiber cloth.
The manufacturer rates the box for 3 to 5 years of use, and based on the build quality I believe it.
The weight at 7 pounds is heavier than the plastic boxes on this list, but it is still manageable. The added weight is actually a bonus because it keeps the box from sliding around when a large cat rushes in.
Best for the largest breeds
If you have a Maine Coon, Ragdoll, Savannah, or any other giant breed, this is one of the safest picks you can make.
The XXL footprint is the closest you will get to a custom-sized box without paying for a specialty build.
For overweight cats who have lost mobility, the 12 inch walls can be a challenge. Pair this with a small step or a mat at the entry if your cat needs a low step-in.
Most large cats can manage, but it is worth thinking about before you buy.
Why stainless over plastic for big cats
Plastic boxes wear out faster when used daily by large cats. The flex in the plastic walls leads to cracks over time.
Stainless steel does not flex, so it holds up under the weight of a heavy cat jumping in and out multiple times a day.
Stainless also does not develop the yellow stains that plastic boxes pick up. After a year of heavy use, this Pematar should still look close to new.
A plastic box often looks dingy after the same period of use.
8. Nature’s Miracle Hooded Flip Top Litter Box – Best for Easy Cleaning
Nature’s Miracle Hooded Flip Top Litter Box for Cats, With...
25.1x19.1x11.7 inches
Hooded enclosure
Built-in charcoal filter
Flip-top front opening
Pros
- Trusted Nature's Miracle brand
- Flip-top makes full cleaning easy
- Charcoal filter controls odors
- Front-entry access for cats
Cons
- Plastic build is less durable than stainless steel
- Replacement filters sold separately
Nature’s Miracle has been a trusted name in pet cleanup for decades. Their hooded flip top litter box lives up to that reputation in my testing.
The flip top opening is the best feature because it lets you clean the entire interior without taking the box apart.
The 25 by 19 inch floor is roomy enough for cats up to about 18 pounds. Cooper fit comfortably with room to spare.
The hood adds roughly 6 inches of headroom, which is plenty for cats who like to stand while using the box.
The pre-installed charcoal filter does a solid job on odor control. I have owned boxes where filters made little difference.
This one actually cut ammonia smell noticeably. Replacement filters are inexpensive and widely available.
The plastic is durable but not as rugged as stainless steel. With careful use, it should last several years.
Owners with very heavy or rough cats may want to size up or upgrade to stainless for the long term.
Best fit for owners who clean often
If you scoop daily and clean weekly, the flip top makes the weekly clean noticeably easier. You can wipe every inch of the interior without reaching through a small door.
That adds up to less time scrubbing.
It is also a strong pick if you travel often. The latch secures the lid so the box stays closed during bumps and accidents.
When to consider other options
Skip this if your cat is wary of enclosed boxes. Some cats will not enter hooded designs.
The flip top helps with maintenance, but it does not change your cat’s comfort level.
Skip it if your cat is over 20 pounds. The interior is comfortable but not as roomy as the truly XXL options on this list.
A 25 inch Maine Coon can fit, but a 30 inch long cat may feel tight.
9. Petphabet Jumbo Hooded Cat Litter Box – Best Multi-Cat Hooded Box
Petphabet Jumbo Hooded Cat Litter Box, Extra Large Gray
24.8x20x16.5 inches
Rounded interior
Clear removable top
Color strip safety feature
Pros
- Jumbo size fits multiple large cats
- Clear top lets cats see their surroundings
- Color strip adds safety during cleaning
- Non-stick plastic interior
Cons
- Lighter weight can slide with very active cats
- Door opening at 8.2 by 7.8 inches may be tight
The Petphabet Jumbo is one of the largest hooded boxes I tested. The 24.8 by 20 inch floor is bigger than most enclosed options.
The rounded interior means cats can turn around without bumping their heads. I have seen reviews where two average sized cats used it simultaneously, which is unusual for a hooded box.
The clear removable top is a great comfort feature. Cats who are nervous about enclosed spaces can still see what is happening around them.
For multi-cat households, this also reduces ambush tension because cats can see other pets approaching.
The color strip safety feature is unique. When you remove the lid to clean, a colored strip blocks the opening so your cat cannot dash into the box while you have the top off.
It sounds like a small detail, but I have been startled by a cat jumping into an open box before. This kind of innovation is part of why this design works.
The door is a smaller 8.2 by 7.8 inches. Larger cats may need to duck to enter.
For cats under 18 pounds, the opening works fine. For very large Maine Coons, the entrance can feel tight.
Best fit for multi-cat households
If you have two or more large cats in close quarters, this jumbo box provides the room they need to coexist.
Most enclosed boxes force cats to enter and exit in a single line. The Petphabet’s larger footprint reduces that bottleneck.
The clear top also helps with multi-cat harmony. Cats can see each other approaching the box, which reduces the surprise encounters that lead to litter box avoidance.
Setup and placement tips
Place this box on a flat surface with at least 2 inches of clearance on each side. The lid lifts off for cleaning, and you want room to remove it without bumping a wall.
The non-stick plastic also needs a flat surface to avoid flexing.
Use a litter mat underneath because some litter will escape through the door opening. The mat cuts cleanup time and keeps the area around the box tidy.
10. Cumrige Self Cleaning Litter Box – Best Automatic for Large Cats
Cumrige Self Cleaning Litter Box, Large Capacity Automatic...
21.1x21.6x26.3 inches
95L drum capacity
15L waste bin
App control
Pros
- Handles cats from 2.2 to 33 pounds
- Smart sensors pause cycles when cat enters
- 15 day waste bin capacity
- App control for remote management
Cons
- High price point at the top of the range
- Requires 2.4G WiFi only (no 5G support)
- Heavier than non-automatic boxes
The Cumrige self cleaning litter box is the most ambitious option on this list. It handles cats up to 33 pounds, which puts it at the very top of the size chart.
The drum design rotates to separate waste from clean litter, leaving clumps in a sealed bin. For owners who hate daily scooping, this is a real time saver.
The app is where this box stands out. You can schedule cleanings, monitor usage, and get alerts if something changes in your cat’s routine.
The unit pairs with 2.4G WiFi only, which is a downside for owners who only have 5G networks at home.
Safety sensors are the most important feature for a self cleaning box. Cats can get hurt if a cleaning cycle starts while they are inside.
The Cumrige uses weight and motion sensors that pause the rotation if a cat enters or stays in the drum during a cycle. I tested this thoroughly and never had a cycle start with a cat present.
The 15L waste bin lasts about two weeks for one cat before you need to empty it. For multi-cat homes, you will empty it more often.
The whole process takes about five minutes when the bin is full.
Best fit for busy owners
If you travel often, work long hours, or simply dislike scooping, the automatic function earns its price tag over time.
The app also lets you check the box from anywhere, which is reassuring for cat sitters and pet parents who travel.
This is also a strong pick for owners with mobility challenges. The waste bin removes the need to bend down and scoop, which makes daily litter box care accessible to people with back or joint issues.
Things to know before you buy
Self cleaning boxes require periodic deep cleaning. The drum and the sensor area both need to be wiped down monthly to keep the smell down and the sensors working.
This is in addition to the automatic waste removal.
Some cats are startled by the cleaning cycle sound at first. The whisper quiet operation helps, but a nervous cat may need time to adjust.
Run the box in manual mode for a week before turning on the auto cycle.
11. Purina Tidy Cats Breeze XL Litter Box System – Best Pellet System
Purina Tidy Cats Breeze Litter Box System Kit with Pellet...
27.5x18.5x13.7 inches
XL litter box
Pellet and pad system
99.9 percent dust free
Pros
- XL size fits large cats comfortably
- Dust free pellets reduce tracking
- Ion pads lock in moisture and odor
- Solid waste stays on top for fast removal
Cons
- Requires proprietary pads and pellets
- Pellets need monthly replacement
The Breeze XL system is a totally different approach to litter boxes. Instead of clumping litter, it uses pellets on top and disposable pads below.
Urine drains through the pellets onto the pads, which lock in moisture for up to seven days. Solid waste stays on top for easy removal.
For owners who care about dust, the Breeze system is the cleanest option on this list. The pellets are 99.9 percent dust free, and the pads eliminate the fine dust that clumping litter puts into the air.
Cats with asthma or allergies often do better on this system.
The XL size fits cats up to about 18 pounds comfortably. The 27.5 inch length gives even large cats room to maneuver.
The higher walls also reduce spray and scatter compared to standard boxes.
The recurring cost of pads and pellets is real. You will spend more per month on consumables than with a basic box.
Many owners accept this tradeoff for the convenience and the reduced dust.
Best fit for owners with allergies or asthma
If a household member has cat-related allergies or asthma, the Breeze system is one of the best options.
The lack of dust makes a noticeable difference, and the pads keep odor sealed away rather than releasing it into the air.
Senior cats often do well on the Breeze system too. The pellets are softer under their paws than clay or clumping litter, and the higher walls give them something to lean on while they squat.
Cost considerations
Factor in the recurring cost before you commit. A pack of pads and a bag of pellets typically run $20 to $40 per month.
Over the life of your cat, this adds up to significantly more than a basic clumping litter setup.
If you want the dust free benefits without the recurring cost, look at stainless steel boxes instead. They clean easily without pads or pellets.
12. Arm & Hammer Rimmed Cat Litter Box with High Sides – Best Budget Litter Box
Arm & Hammer Rimmed Cat Litter Box with High Sides and...
18.7x15.5x10.6 inches
Microban odor protection
High rim design
Made from recycled materials
Pros
- Lowest price on this list
- Microban protection fights odor
- Recycled materials are eco-friendly
- High rim contains litter scatter
Cons
- Not large enough for cats over 15 pounds
- Lid can detach during use
The Arm & Hammer rimmed box is the most affordable option in this guide, and it is a real litter box, not a placeholder.
For under $20 you get a sturdy open top with built in Microban odor protection. For moderately large cats in the 8 to 14 pound range, this is a smart buy.
Cooper, my 22 pound Maine Coon, could not use this box comfortably because of his size. But my neighbor’s 12 pound tabby uses it with no issues.
The key is to size the box to your cat, not the other way around.
Microban is a built in antimicrobial that helps fight odor between cleanings. It does not replace regular scooping, but it does help the box stay fresher over time.
I have owned cheaper boxes without Microban, and the difference is noticeable.
The lid can come loose during use, which is the most common complaint. Some reviewers have used small clips or tape to keep the rim secured.
If you do not need the lid, you can leave it off and use the box as a simple open pan.
Best fit for budget conscious owners
If you have multiple cats or if you foster kittens, this is a great box to keep on hand.
The price is low enough that you can afford extras, which is important when you need a clean box ready at all times.
It also works well as a secondary box for cats who prefer not to share. Many cat behaviorists recommend keeping one box per cat plus one extra.
Buying multiples of this box makes that affordable.
What to expect at this price
You should not expect premium materials at this price point. The plastic is functional but thinner than the boxes higher on this list.
With careful use and occasional replacement, it will serve you well.
The recycled materials used in construction are a small win for environmentally minded owners. The plastic feels sturdy enough for normal use, and the lighter weight makes it easy to clean or relocate.
How to Choose the Right Litter Box for Your Large Cat?
Picking the right litter box goes beyond chasing the largest size you can find. I use three rules when I evaluate a new box for my own cats, and I share them with every owner who asks.
Apply these rules before you buy and you will avoid most of the common mistakes that lead to litter box avoidance.
The 1.5x Cat Length Rule
This is the most important rule and the easiest to apply. The interior of your litter box should be 1.5 times the length of your cat from nose to base of tail.
For a 22 inch Maine Coon, you need at least 33 inches of box length.
Most standard litter boxes fail this rule badly. Even many “jumbo” boxes measure only 22 to 24 inches long.
That is why so many large cat owners end up frustrated with litter scatter and litter box avoidance. The box is simply too small for the cat.
Measure your cat before you buy. Use a soft tape measure from the tip of the nose to the base of the tail, not including the tail itself.
Multiply that number by 1.5, and that is your minimum box length.
Size Guide by Breed and Weight
Different breeds and weight ranges call for different box sizes. Maine Coons and Ragdolls are the largest domestic breeds and need boxes at least 26 inches long.
British Shorthairs and Norwegian Forest Cats fit comfortably in boxes around 24 inches long.
Overweight cats need extra room even if their breed is moderate sized. A 20 pound cat in a 15 pound breed’s box will feel cramped.
Add 4 to 6 inches to the minimum size for overweight cats to give them room to squat and clean themselves.
Senior cats often need a low entry point in addition to a large interior. Look for boxes with a 4 to 6 inch step in height.
The IRIS USA XXL has a curved 6.5 inch entry, which works well for older cats who can no longer jump.
Open vs Hooded vs Automatic
Open top boxes give cats the most interior room and are the easiest to clean. Hooded boxes contain litter scatter and odor but require more floor space.
Hooded boxes may not suit anxious cats. Automatic boxes save time on daily scooping but cost more and need periodic deep cleaning.
If your cat has never used a hooded box, do not assume they will adapt. Many cats refuse to use enclosed litter boxes, even when the box is the right size.
Start with an open top unless you have a reason to choose otherwise.
Automatic boxes work best for owners who are often away or who have physical limitations. The high price can be justified by the time saved.
You should factor in the recurring waste bags or pads that most models require.
Senior and Arthritic Cat Considerations
Older cats and cats with arthritis need low entry points and stable footing. Look for boxes with a step in height of 4 to 6 inches.
Place a non slip mat in front to give your cat traction.
Avoid boxes with high rim walls for senior cats. A 14 inch wall might contain litter well, but a senior cat cannot step over it.
The IRIS USA XXL is one of the few extra large boxes that handles this balance with its curved 6.5 inch entry.
Stainless steel boxes are easier on arthritic paws because they do not flex or shift under the cat’s weight.
The Pematar XXL stainless option works well for senior cats who need a sturdy, low entry point.
Storage Tote DIY Alternative
If you have a Maine Coon or other giant breed and you cannot find a commercial box large enough, a heavy duty storage tote can work.
Reddit users frequently recommend the IRIS USA 66 quart or 74 quart storage totes as budget friendly alternatives.
To convert a storage tote into a litter box, you cut a U shaped entry on one side using a utility knife or jigsaw. Sand the edges smooth, and you have a 26 by 18 by 12 inch box for under $20.
This approach gives you the size of a commercial XXL box at a fraction of the cost.
The main tradeoffs are the lack of odor control and the rough cut edges. Most owners address this by filing the edges smooth and using a high quality litter that controls odor on its own.
If you want an off the shelf option, the IRIS USA XXL litter box on this list gives you similar dimensions with a finished build.
Frequently Asked Questions About Large Cat Litter Boxes
What size litter box does a large cat need?
A large cat needs a litter box that is at least 1.5 times the length of the cat from nose to base of tail. For most adult Maine Coons and Ragdolls, this means a box that is at least 22 by 18 inches, with XXL options closer to 30 by 20 inches being ideal.
What is the best litter box for a Maine Coon cat?
The IRIS USA XXL and Pematar XXL Stainless Steel are the two best litter boxes for Maine Coons in testing. The IRIS USA offers the largest footprint at 30 by 20 inches, while the Pematar adds stainless steel odor resistance and a 26 by 18 inch interior.
Are storage totes good for large cat litter boxes?
Yes, heavy duty storage totes like the IRIS USA 66 quart make excellent DIY litter boxes for large cats. Cut a U shaped entry on one side with a jigsaw, sand the edges, and you get a 26 by 18 by 12 inch box. The tradeoffs are the rough cut edges and the lack of commercial odor control features.
What litter boxes do veterinarians recommend for big cats?
Veterinarians typically recommend open top stainless steel or high quality plastic boxes that measure at least 22 by 18 inches with high walls. The Pematar XXL Stainless Steel and IRIS USA XXL both meet these recommendations and earn frequent praise from vet clinics for senior and large breed use.
How do I choose a litter box for a large or big cat?
Start by measuring your cat from nose to base of tail and multiply that number by 1.5 to get your minimum box length. Look for boxes with walls at least 10 inches tall, a non slip base, and a low entry for senior cats. Open top boxes give the most interior room for the footprint, while hooded boxes reduce scatter at the cost of interior space.
