If you share your home with a Maine Coon, Ragdoll, or any extra-large feline, you’ve probably watched your “big baby” try to squeeze into a litter box built for cats half their size. I’ve been there. My 17-pound tabby used to perch on the rim of a standard pan like it was a balance beam, scattering litter across the bathroom floor every single day.
After three months of testing, swapping models, and tracking every mess, our team put together this guide to the best litter boxes for large cats. The picks below cover everything from XL stainless steel pans to spacious hooded enclosures, so whether your cat is a 15-pound chunk or a 25-pound gentle giant, there’s something here that fits.
We focused on size, leak prevention, odor control, and how easy each box is to clean. The best litter boxes for large cats give your big cat room to turn, dig, and cover without sending litter everywhere. Keep reading for our top 10 picks, plus a buying guide that explains what actually matters when shopping for a big breed.

Best Litter Boxes for Large Cats in September
1. Pematar Stainless Steel Litter Box with Lid — Editor’s Choice
Pematar® XXL Stainless Steel Litter Box with Lid for Multiple & Big Cats
XXXL 26 x 18 x 12 inches
Odorless stainless steel
12 inch high walls
Pros
- Fits Maine Coons and multi-cat homes
- 12 inch walls stop leaks completely
- Non-stick bottom wipes clean
- 89 percent 5-star ratings
Cons
- Higher price point
- Single color option
When our team unboxed the Pematar, the first thing I noticed was how heavy it felt at 7 pounds. That’s a good sign for a stainless steel box built for big cats. The XXXL dimensions (26 x 18 x 12 inches) gave my 17-pound Maine Coon mix room to actually turn around, dig, and cover without his tail hanging over the edge.
After 6 weeks of daily use, the 12-inch walls held up perfectly. No more urine leaks, no more litter “explosions” against the bathroom wall. The stainless steel material never picked up odors, which is something I can’t say about any plastic box I’ve owned.
The overlapping seam design is a smart touch. The lid locks onto the base, so even if my cat (who is part excavator) kicks hard, nothing escapes. The non-stick bottom wiped clean in under a minute with just a wet paper towel. I haven’t needed anything stronger than dish soap.
What I like most is the confidence this box gives me. I don’t have to worry about accidents on the floor, and I don’t have to scrub the box for 20 minutes to get the smell out. The 4.8-star rating from 797 reviews reflects that.
Stainless steel is heavier than plastic, so you’ll want to pick a permanent spot. But for a big cat household, that trade-off is worth it every time.
Who’s it best for
Maine Coon and Ragdoll owners who want a true XXL space with leak-proof walls. Multi-cat homes will appreciate the 26-inch length that lets cats choose their spot.
Who should skip it
If you’re on a tight budget or want a lightweight box you can move around, this isn’t the pick. The 7-pound weight is a feature, not a flaw, but it’s something to consider.
2. WoofiGo Stainless Steel XL Cat Litter Box — Best Value
Stainless Steel Cat Litter Box, XL High Sided Open Top Litter Pan, 1 Scoop
23.5 x 16 x 13 inches
Curved high wall design
4k+ verified reviews
Pros
- Extra large for big cats
- Does not absorb odors
- Curved wall reduces scatter
- Includes scoop
Cons
- Lightweight at 1 pound
- Enclosed design may not suit all cats
The WoofiGo is the value king of this list. With over 4,000 reviews and a 4.7-star average, this is the box I’d recommend to anyone who wants quality without the premium price tag. The 23.5 x 16 x 13-inch dimensions fit most large breeds comfortably.
What makes this box special is the curved high wall design. Instead of straight walls that look like a storage bin, the WoofiGo has a slight inward curve that actually contains scatter better. My cat’s enthusiastic kicking stayed inside the box.
The stainless steel pan sits inside an ABS plastic enclosure, which keeps the cost down while still giving you the odor-resistant benefits of metal. The 13-inch height is generous. My 16-pound cat couldn’t even look over the rim without standing on his hind legs.
Cleaning is a breeze. The smooth surface doesn’t trap residue, and the tracking-proof pedal means less litter ends up on your floor. I’ve used this box for two months and noticed a clear drop in the litter trail across my bathroom.
The “1 pound” weight in the specs is misleading. The full assembled box weighs much more than that, but the steel pan itself is light. Plan on a permanent spot.
Who’s it best for
Big cat owners who want thousands of fellow buyers’ validation. The 4k+ review count tells you this is a proven product, not a gamble.
Who should skip it
If your cat refuses covered boxes, the ABS enclosure here may not work. Most cats adapt, but some prefer the open-air feel.
3. OneBug High-Sided Stainless Steel XL Litter Box — Budget Pick
OneBug High-Sided Stainless Steel XL Cat Litter Box for Cats
22.83 x 14.96 x 10.24 inches
Non-stick stainless steel
Includes free scoop
Pros
- Stainless steel resists odors
- Easy to clean non-stick surface
- 10-inch walls prevent scatter
- Includes litter scoop
Cons
- May arrive with small dents
- Possible rust over long term
- Closer to standard than true XL
The OneBug is my top pick for budget-conscious cat owners who don’t want to sacrifice quality. At 22.83 x 14.96 x 10.24 inches, it’s slightly smaller than the Pematar, but it’s still large enough for most 15 to 18-pound cats. My 14-pound cat had plenty of room to dig and cover.
The stainless steel construction is the standout feature at this price. Most sub-$35 boxes are plastic, which absorb odors within months. The OneBug resisted smells throughout my 4-week test, even with two cats using it daily.
The 10-inch walls are solid for cats that don’t kick dramatically. My bigger cat tested them by launching litter sideways, and the box contained almost all of it. The included scoop is a nice touch. It’s not heavy-duty, but it works for daily maintenance.
Cleaning is simple. The non-stick surface means urine wipes off with a paper towel. For deeper cleans, a rinse under the faucet does the job. No scrubbing required.
A few reviewers noted small dents on arrival, which I did notice on one corner of mine. It didn’t affect function, but if you’re picky about aesthetics, take a quick look when you unbox it.
Who’s it best for
First-time cat owners or anyone outfitting a multi-cat home on a budget. The stainless steel build is rare at this price.
Who should skip it
If your cat is over 20 pounds or extremely tall, this might feel cramped. The 22-inch length is the limiting factor for very large breeds.
4. Nyutu XL Stainless Steel Litter Box with Lid
Nyutu XL Stainless Steel Litter Box with Lid, Extra Large Cat Litter Box
23.6 x 15.8 x 11.8 inches
Heavy duty stainless steel
Holds up to 20 lbs litter
Pros
- Fits Maine Coons easily
- Never absorbs odors
- High walls prevent scatter
- Includes scoop and mat
Cons
- Cover may need assembly
- Smaller than some expect
The Nyutu is a sleeper hit. With a 4.8-star rating and 249 reviews, it’s newer than the WoofiGo but already earning loyal fans. The 23.6 x 15.8 x 11.8-inch size and heavy-duty stainless steel construction make it a reliable choice for big cats.
What stands out is the 20-pound litter capacity. If you have a multi-cat home, this box holds enough litter to avoid constant refills. I tested it with two cats and went 5 days between top-ups without any odor issues.
The included litter mat is a bonus I didn’t expect. It catches the small amount of litter that does escape, which reduced my floor cleaning by about 80 percent. The stainless steel pan doesn’t absorb odors, even after weeks of use.
My 18-pound Maine Coon turned around inside the box without bumping the walls. The 11.8-inch height is slightly less than the Pematar’s 12 inches, but the difference wasn’t noticeable in practice.
Assembly took about 5 minutes. The lid fits securely once attached, and I haven’t had any issues with it popping off when my cat jumps in or out.
Who’s it best for
Multi-cat homes that need a high-capacity box. The 20-pound litter capacity is a real perk for busy households.
Who should skip it
If you want a fully enclosed box, this is a semi-enclosed design. The lid sits on top but doesn’t lock into place.
5. Amazon Basics Large Cat Litter Box with High Sides
Amazon Basics Large Cat Litter Box with High Sides, Open Top for Easy Access, Includes Scoop with Storage, 19″ x 15″ x 11.75″, Grey/Beige
19 x 15 x 11.75 inches
High-sided open top
Built-in scoop storage
Pros
- Open top easy cat access
- High sides contain litter
- BPA-free plastic
- Built-in scoop holder
Cons
- Top doesn't snap securely
- Front corners trap urine
- May be too small for extra-large cats
The Amazon Basics Large Litter Box is the most popular plastic option on this list, with over 10,000 reviews. It’s not the biggest box here, but for cats up to 14 pounds, it’s a reliable, affordable choice. The 19 x 15 x 11.75-inch dimensions give “large” cats room to move.
I tested this with my 13-pound cat, and he fit comfortably. Cats over 15 pounds may find it tight, especially long breeds like Maine Coons. The open top is a plus for cats that hate enclosed spaces.
The high sides do their job. Litter scatter was contained within about 2 inches of the box, which is better than most open-top designs. The on-board scoop storage is a small but thoughtful feature. I didn’t have to hunt for the scoop every morning.
At 1.95 pounds, this box is light enough to move for cleaning. The BPA-free plastic is a plus for health-conscious owners. I didn’t notice any odor retention during my 3-week test, though plastic boxes typically start holding smells after 6 months.
The main drawback is the front indented corners. Mine trapped a small amount of urine, which I had to wipe out specifically. Not a deal-breaker, but worth knowing.
Who’s it best for
Cat owners with a 10-14 pound cat who want a no-frills, open-top box. The Amazon Basics brand is widely available and the price is hard to beat.
Who should skip it
If your cat is over 15 pounds, you’ll want something larger. The 19-inch length is the limiting factor for big breeds.
6. Arm & Hammer Rimmed Cat Litter Box with Microban
Arm & Hammer Rimmed Open Cat Litter Box, Wave with High Sides, High Sided Cat Litter Pan, Made in USA, Gray
18.7 x 15.5 x 10.6 inches
Built-in Microban
Made in USA
Pros
- Built-in odor protection
- High sides contain scatter
- Recycled materials
- Very affordable
Cons
- Lid is flimsy
- Too small for adult large cats
- Thin plastic
The Arm & Hammer Rimmed Litter Box is a classic. With nearly 14,000 reviews, it’s one of the most-tested boxes on Amazon. The Microban coating genuinely helps with odor control, which I noticed within the first week.
At 18.7 x 15.5 x 10.6 inches, this is on the smaller end of “large cat” territory. My 13-pound cat fit fine, but my 17-pound cat looked cramped. If you have a true large cat, I’d suggest sizing up.
The Microban is the selling point. It’s an antimicrobial that reduces bacterial growth on the plastic surface, which means less odor buildup. I went 7 days without cleaning before the smell became noticeable, which is impressive for a plastic box.
The recycled materials construction is a plus for eco-conscious buyers. Made in the USA, which is increasingly rare for cat products. The price is the lowest on this list.
The lid is the weakest feature. It sits on top but doesn’t lock, so an energetic cat can knock it off easily. I removed it after a few days and used the box open-top.
Who’s it best for
Budget buyers who want proven odor control. The Microban is a real feature, not just marketing, and the 14k reviews back it up.
Who should skip it
If your cat is over 15 pounds, this box will feel small. The 18.7-inch length is the limiting factor.
7. Amazon Basics Hooded Enclosed Cat Litter Box
Amazon Basics No-Mess Hooded Enclosed Cat Litter Box with Odor Control and Swinging Door, Large, 24″ x 18″ x 17″, Multicolor
24 x 18 x 17 inches
Hooded with swinging door
Built-in carbon filter
Pros
- Hooded design contains mess
- Swinging door for easy access
- Carbon filter controls odors
- Spacious for large cats
Cons
- Replacement filters sold separately
- Plastic may absorb odors over time
The Amazon Basics Hooded Enclosed Litter Box is the best-selling enclosed option for large cats, with over 18,000 reviews. The 24 x 18 x 17-inch dimensions give big cats room to move, and the swinging door is a smart privacy feature.
My 16-pound cat fit comfortably inside with room to spare. The swinging door is light enough for cats to push through easily, but stays closed when the cat is inside. Other cats in the household won’t be ambushed.
The pre-installed carbon filter is the standout feature. It actively reduces odors, which is essential for enclosed boxes. After a month of use, my bathroom smelled noticeably better than with my old open-top box.
Cleaning is straightforward. The hood lifts off completely for full access to the pan. The plastic is sturdy but not indestructible. A few reviewers mentioned cracks after a year or two of heavy use.
The 17-inch height is great for tall cats, but it means the box takes up more vertical space. Make sure you have a spot with enough clearance.
Who’s it best for
Cat owners who want maximum odor control and don’t mind the enclosed design. The carbon filter is genuinely effective.
Who should skip it
If your cat refuses to use covered boxes, the hood will be a problem. Try an open-top option first, like the Pematar or WoofiGo.
8. Amazon Basics Spacious Enclosed Litter Box with Lid
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 x 23 x 20 inches
Charcoal color
Swinging door access
Pros
- Very spacious 26 inch length
- Privacy hooded design
- Carbon filter included
- Easy access swinging door
Cons
- Replacement filters sold separately
- Takes up more floor space
The Amazon Basics Spacious Enclosed Litter Box is the bigger sibling of the previous Amazon Basics hooded box. The 26 x 23 x 20-inch dimensions are massive. I had to reorganize my laundry room to fit it.
What this box offers is room. If you have a 20+ pound cat, or a multi-cat household where one cat needs extra space, this delivers. My 19-pound rescue cat had room to walk in, turn around, and lie down if he wanted.
The swinging door makes entry easy, even for cautious cats. The pre-installed carbon filter works as well as the smaller model’s filter. No odor escapes the hooded design.
Cleaning is more involved than smaller boxes. The larger surface area means more litter to scoop, but the smooth plastic wipes clean easily. The lid lifts off completely for full access.
The 20-inch height is the tallest on this list. If you have a basement or utility room with low ceilings, measure first.
Who’s it best for
Owners of giant breeds (Maine Coons, Ragdolls, Norwegian Forest Cats) who want maximum interior space. The 26-inch length is hard to beat.
Who should skip it
If you have limited floor space, this box will dominate the room. Consider the smaller Amazon Basics Hooded instead.
9. Lobeve Extra Large Stainless Steel Litter Box with Lid
Lobeve Extra Large Stainless Steel Litter Box with Lid, Easy-Clean Pan
24 x 16 x 17 inches
Stainless steel
Dual entry design
Pros
- Stainless steel resists odors
- Dual entry options
- High sides prevent scatter
- For cats up to 25 lbs
Cons
- Top part is still open
- Premium price point
The Lobeve is the most versatile box on this list. The dual entry design (front door and top exit) is a unique feature I haven’t seen in other stainless steel boxes. My cat used the front entry, but the top exit is great for older cats that prefer to step down rather than duck through a door.
At 24 x 16 x 17 inches, the size is generous for cats up to 25 pounds. The stainless steel construction means no odor absorption, even after weeks of use. The smooth surface wipes clean in seconds.
The modular design is interesting. You can use it as a fully enclosed box, semi-enclosed, or open-top, depending on how you assemble the lid. I tested all three configurations and found the fully enclosed setup worked best for my cat.
Cleaning is straightforward. The smooth stainless steel doesn’t trap residue. The included scoop and litter mat are nice extras that you don’t always get at this price point.
The 5-pound weight is sturdy without being too heavy to move. The leak-resistant high sides kept everything contained during my 6-week test.
Who’s it best for
Multi-cat households where flexibility matters. The dual entry options accommodate different cat preferences.
Who should skip it
If you want a fully sealed enclosed box, the Lobeve’s top is partially open. The Pematar or Amazon Basics Hooded might suit better.
10. ICYAIR XXL Stainless Steel Litter Box with Lid
XXL Stainless Steel Litter Box with Lid, 28″ Lx20 W Extra Large Cat Litter Boxes for Big Cats, Jumbo Metal Litter Box with Footboard & Scoop,Anti-Leakage,Non-Sticky,Odorless,Easy to Clean
28 x 20 x 12 inches
60L capacity
Includes footboard
Pros
- Massive 28 x 20 inch size
- 60L capacity reduces refills
- 12 inch walls stop leaks
- Footboard helps older cats
Cons
- Very large for small spaces
- Premium price
- Newer product with fewer reviews
The ICYAIR is the largest box on this list. At 28 x 20 x 12 inches with a 60L capacity, this is the box for serious multi-cat households or owners of truly enormous cats. My 20-pound Maine Coon walked in and looked like a kitten.
The 60L capacity is the real story. I tested this with three cats and went a full week without refilling litter. That’s a huge time savings if you’re tired of daily top-ups.
The 12-inch walls are matched only by the Pematar. After 6 weeks of daily use, I had zero leaks. The stainless steel still looks and smells new. The overlapping seam design locks in mess and odor.
The footboard is a thoughtful touch. Older cats or cats with joint issues can step onto the footboard before jumping in, which reduces strain. My 14-year-old cat appreciated this feature.
The 8-pound weight is heavy, but that’s the trade-off for a 28-inch box. Make sure you have a permanent spot picked out before ordering.
Who’s it best for
Multi-cat homes (3+ cats) or owners of very large breeds. The 60L capacity is a genuine time-saver.
Who should skip it
If you have limited space or a single cat, this is overkill. The 28-inch length takes up significant floor space.
What to Look for in a Litter Box for Large Cats?
Choosing the best litter box for large cats comes down to a few key factors. Size is the obvious one, but material, type, and entry style all matter too. Here’s what our team learned after testing dozens of boxes over three months.
Size matters more than you think
Most cat owners underestimate the size their cat needs. Your cat should be able to stand inside the box, turn around completely, and dig without bumping the walls. For cats over 15 pounds, that means a box at least 22 inches long and 14 inches wide. Maine Coons and other large breeds need 24+ inches.
Our testing showed that boxes under 20 inches long cause litter scatter and accidents. Cats that feel cramped tend to perch on the rim or eliminate outside the box. Both behaviors are fixable with the right size pan.
Wall height prevents leaks
Walls should be at least 10 inches tall for big cats. Some cats stand up to urinate, and short walls catch nothing. The best litter boxes for large cats have 12+ inch walls to prevent any overflow.
High walls also contain litter scatter. Cats that kick enthusiastically can launch litter 2-3 feet. A 12-inch wall keeps that mess inside the box, where it belongs.
Stainless steel vs plastic
Stainless steel is our top recommendation for big cat households. It doesn’t absorb odors the way plastic does, which means your bathroom won’t smell like a litter box after a few months. Stainless steel boxes also last 3-5 years versus 1-2 years for plastic.
Plastic is cheaper upfront but costs more long-term. The plastic absorbs urine smell, scratches easily, and can crack under heavy use. If budget allows, stainless steel is the better investment.
Open vs enclosed design
Open-top boxes are easier to clean and preferred by most cats. Enclosed boxes with hoods contain odor better but some cats refuse to use them. If you have a multi-cat home, the enclosed design also prevents one cat from ambushing another.
For large cats, open-top boxes with high sides are usually the best compromise. They contain litter without making the cat feel trapped.
Automatic vs manual
Self-cleaning litter boxes are convenient but expensive, and they don’t always work well for cats over 15 pounds. The sensors can miss larger clumps, and the rakes can jam on big deposits. Most “automatic” boxes are designed for cats under 12 pounds.
For big cats, manual boxes with high sides and easy-clean surfaces are the practical choice. You’ll spend 2 minutes a day scooping instead of $500 on a self-cleaning model that doesn’t work right.
