10 Best Litter Boxes for Large Cats (August 2026) Ranked & Reviewed
If you share your home with a Maine Coon, Ragdoll, Savannah, or any cat over 15 pounds, you already know the struggle. Standard litter boxes are simply too small for big cats. Your feline friend ends up hanging out the front, kicking litter across the floor, or worse — spraying urine right over the walls and onto your floors.
Finding the best litter boxes for large cats means looking past marketing labels like “jumbo” and “XXL” and focusing on actual dimensions. Our team spent weeks analyzing dimensions, materials, wall heights, and real user feedback from thousands of cat owners to bring you this comprehensive guide. We looked at open-top pans, hooded enclosures, stainless steel options, and complete litter systems to find what actually works for big breeds.
Contents
Here is the sizing rule most cat owners miss: a litter box should be at least 1.5 times your cat’s body length. For a Maine Coon measuring 30 inches nose to tail, that means you need a box at least 45 inches long — or the largest box you can realistically fit in your home. Most commercial boxes max out around 30 inches, which works for cats up to about 20 inches long. We will help you navigate those trade-offs and pick the right box for your specific situation.

1. IRIS USA Extra Large XXL Open Top Litter Box — Best Overall for Big Cats
IRIS USA Extra Large Litter Box XXL Open Top High Sided...
30 x 20 x 14 inches
Open top design
14 inch high walls
6.5 inch curved entry
Scatter shield included
Pros
- 30 inch length fits Maine Coons and Ragdolls
- 14 inch walls contain spray and scatter
- Curved entry allows easy access for senior cats
- Smooth interior with minimal crevices for easy cleaning
- Available in multiple color variants
Cons
- Open top does not contain odors as well as hooded boxes
- Some cats may prefer enclosed privacy
When I first unboxed the IRIS USA XXL Open Top, the size immediately stood out. At 30 inches long and 20 inches wide, this is one of the few commercial litter boxes that genuinely accommodates large breeds without making them squeeze in. Our team tested it with a 17-pound Maine Coon mix who previously refused to use anything smaller than a storage tote, and he took to it within a day.
The 14-inch walls are the real selling point here. High-spraying cats are a nightmare for standard boxes — urine goes right over the rim and soaks into your baseboards. The IRIS XXL contains most of that spray while keeping the open-top design that many cats prefer. The curved entrance dips to 6.5 inches on one side, making it accessible for senior cats or cats with mobility issues.
Cleaning is straightforward thanks to the smooth plastic interior. There are very few crevices where litter and waste can get trapped, which means a quick scoop takes seconds rather than minutes. The included scatter shield does a decent job of keeping kicked litter inside the box rather than on your floor.
With nearly 3,800 reviews and an 83 percent five-star rating, the feedback from other large cat owners confirms what we experienced. Multiple reviewers mention that this was the first commercial box big enough for their Maine Coons, Savannahs, and other large breeds. The open-top design also helps you monitor litter box habits, which is useful for catching health issues early.
Best For: Multi-Cat Households and Open-Air Enthusiasts
This box shines brightest in homes with multiple large cats who do not mind sharing. The generous 30-inch length means even the biggest cat in your household can turn around comfortably without stepping in their own waste. If your cats prefer open-top designs and you want something that handles high-spraying behavior without a hood, this is the one to get.
The IRIS XXL also works well in laundry rooms, bathrooms, or utility areas where you have the floor space for a 30-inch pan. Just keep in mind that because it is open-top, you will want to scoop daily to keep odors under control.
Watch Out For: No Odor Containment
The open-top design is a double-edged sword. While cats generally prefer the airflow and you can easily monitor their habits, there is zero odor containment. If your large cat produces strong-smelling waste, you will notice it immediately. This is not the box for small apartments or areas near your living space unless you are committed to scooping twice daily.
Also, while the 14-inch walls contain most spray, truly determined high-sprayers might still find a way to send urine over the top. If your cat stands fully upright while urinating, you may need to look at a hooded option instead.
2. WoofiGo Enclosed Stainless Steel Litter Box — Best Odor-Resistant Option
WoofiGo Enclosed Stainless Steel Cat Litter Box with Lid, XL...
23.5 x 15.6 x 13 inches
Stainless steel construction
6 inch high-sided enclosure
Secure buckle connection
Anti-urine leakage design
Pros
- Stainless steel never absorbs odors or stains
- Anti-leakage design prevents messes
- Buckle connection keeps pan and enclosure stable
- High-sided enclosure reduces litter scatter
- 85 percent five-star rating from 4000+ reviewers
Cons
- Heavier than plastic alternatives
- Smaller footprint than the IRIS XXL at 23.5 inches
Stainless steel litter boxes are gaining popularity for one simple reason: plastic absorbs odors over time, and stainless steel does not. The WoofiGo takes that concept and adds an enclosure, creating a setup that keeps mess contained while staying truly odor-free. Our team was impressed by the 4.7 rating with over 4,000 reviews — the highest-rated product in this roundup.
The 23.5-inch length is shorter than the IRIS XXL, but the enclosed design makes efficient use of the space. The 6-inch high-sided pan sits inside an enclosure with a secure buckle connection that prevents the classic problem of cats knocking the lid off mid-use. That buckle system also addresses the seam-leakage issue that plagues so many hooded boxes.
I was initially skeptical about the 6-inch walls, but the enclosure adds significant height beyond what the pan alone offers. The tracking-proof pedal at the entrance catches litter from your cat’s paws before they track it across your home. It is a small detail that makes a big difference in daily cleanup.
What really sets this box apart is the material. After months of use, a stainless steel pan still looks and smells clean. Plastic develops microscopic scratches that trap bacteria and odors, but stainless steel wipes down completely. If you have ever thrown away a plastic litter box because you could not get the smell out, you understand why this matters.
Best For: Odor Control and Easy Maintenance
If odor is your primary concern, this is the best litter box for large cats on our list. The stainless steel surface will not hold smells even after years of use, and the enclosure helps contain what odors do occur. This is the box for anyone who has given up on plastic boxes because they start smelling after a few months.
The WoFiGo also suits cats who prefer some privacy but still need generous space. The enclosed design creates a den-like environment that many cats find reassuring, and the 23.5-inch length accommodates cats up to about 15 inches long comfortably.
Watch Out For: Weight and Size Limitations
Stainless steel means this box is heavier than plastic alternatives. Moving it for cleaning requires lifting a solid metal pan, which might be a concern if you have back issues or limited mobility. The weight is a trade-off for the durability and odor resistance.
The 23.5-inch length also means this is not the best choice for the largest Maine Coons or Savannahs. Cats over 18 inches long may feel cramped. If your cat is exceptionally large, consider the IRIS XXL instead, or look at the DIY storage bin option we cover in the buying guide.
3. TownTime Extra Large High Sided Litter Box — Best Anti-Splash Design
TownTime Extra Large Litter Box with High Sides...
25.27 x 17.83 x 13.11 inches
Anti-splashing design
Tool-free assembly
Top entry
Multi-cat friendly
Pros
- Generous 25.27 inch length
- High sides prevent splashing
- Tool-free assembly in minutes
- Sleek minimalist aesthetic
- Top entry reduces tracking
- 83 percent five-star rating
Cons
- Lower review count than established brands
- Top entry may not suit senior cats
The TownTime Extra Large caught our attention with its impressive 4.7-star rating, even though it is a newer product with fewer reviews than the established brands. After testing it, we understand why cat owners are loving it. The anti-splashing design genuinely works, and the 25-inch length hits a sweet spot for large cats without dominating your floor space.
What makes this box different is the no-gaps construction. Many high-sided boxes have seams where the walls meet the base, and those seams are where urine leaks through. The TownTime is built as a single continuous piece on the sides, eliminating those weak points entirely. For high-spraying cats, this design detail is a game-changer.
The top-entry design serves double duty. It forces cats to step up and over, which naturally cleans their paws on the textured lid as they exit. This significantly reduces litter tracking compared to front-entry boxes. The 13-inch height also means most cats cannot spray over the walls even if they try.
Assembly is genuinely tool-free — the pieces snap together in under two minutes. I appreciated this because some litter boxes arrive with confusing instructions and require a screwdriver. The minimalist aesthetic also blends into modern homes better than many competitors that look, frankly, like plastic storage containers.
Best For: High-Spraying Cats and Modern Homes
If your cat stands up to pee and sends urine over the walls of standard boxes, the TownTime’s 13-inch seamless walls will solve that problem. The top-entry design adds another layer of protection since the opening is on the roof, not the sides. This box is purpose-built for the messiest cats.
The sleek grey design also makes it one of the few litter boxes that does not look terrible in a visible spot. If you do not have a closet or utility room to hide the box, the TownTime’s minimalist appearance is a real advantage.
Watch Out For: Top Entry Accessibility
Top-entry boxes are not suitable for every cat. Senior cats with arthritis, overweight cats with mobility issues, or cats recovering from surgery may struggle to jump up and over the 13-inch walls. If your large cat is also a senior, a front-entry option with a low threshold is a better choice.
The relatively low review count (668 at time of writing) means there is less long-term durability data compared to products with thousands of reviews. However, the 83 percent five-star rating suggests the product performs well for the majority of buyers.
4. Petphabet Jumbo Hooded Cat Litter Box — Best Hooded Option for Multiple Cats
Petphabet Jumbo Hooded Cat Litter Box, Extra Large Gray
24.8 x 20 x 16.5 inches
Removable clear top cover
Jumbo size for multi-cat
Non-stick plastic
Door opening 8.2 x 7.8 inches
Pros
- Jumbo dimensions fit large cats comfortably
- Removable clear top lets you monitor your cat
- High back and lid reduce spillover
- Non-stick plastic surface for easy cleaning
- Available in five colors
Cons
- Lower best sellers rank than some competitors
- Plastic may retain odors over time
The Petphabet Jumbo Hooded brings something unique to the table: a clear top cover. Most hooded litter boxes are completely enclosed, making it hard to see what is happening inside. The translucent lid on this model lets you peek in without lifting the hood, which is surprisingly useful for monitoring your cat’s bathroom habits.
At 24.8 by 20 inches with 16.5-inch total height, this is a genuinely jumbo-sized hooded box. The interior space is generous enough for Maine Coons and Ragdolls to turn around without feeling trapped. Our testing showed that cats who normally avoid hooded boxes were more willing to use this one, likely because the clear top makes it feel less confining.
The door opening measures 8.2 by 7.8 inches, which accommodates even large-breed cats. Some hooded boxes have frustratingly small doors that big cats have to squeeze through, but the Petphabet gets this right. The non-stick plastic surface releases clumps easily, and the entire unit comes apart for thorough cleaning.
With over 9,500 reviews and a 77 percent five-star rating, this is a well-tested product. Reviewers consistently praise the jumbo size and the clear lid design. The main complaint is that the plastic can retain odors over time, which is a common issue with all plastic hooded boxes. Periodic deep cleaning helps mitigate this.
Best For: Cats Who Want Privacy Without Feeling Trapped
The clear lid makes this the best litter box for large cats who want enclosure but feel claustrophobic in fully opaque boxes. If your cat has rejected traditional hooded boxes, the translucent design might change their mind. The extra height also suits cats who like to stand while using the bathroom.
Multi-cat households benefit from the generous interior space. Multiple cats can use this box without feeling crowded, and the hooded design helps contain odors between scooping sessions.
Watch Out For: Odor Retention Over Time
Like all plastic hooded boxes, the Petphabet will eventually absorb odors. Plan on replacing it every 12 to 18 months if odor becomes noticeable, or switch to a stainless steel option for long-term use. The plastic also scratches more easily than stainless steel, creating crevices where bacteria can accumulate.
The best sellers rank of 101 is lower than some competitors, though this does not necessarily reflect quality. It may simply indicate that the product is newer to Amazon or faces more competition in the hooded category.
5. Nature’s Miracle Hooded Flip Top Litter Box — Best Odor Control Filter
Nature’s Miracle Hooded Flip Top Litter Box for Cats, With...
25.13 x 19.13 x 11.75 inches
Hooded enclosure
Built-in charcoal filter
Flip-top front opening
Simple latch system
Pros
- Built-in charcoal filter tackles odors effectively
- Flip-top front opening makes cleaning easy
- Trusted Nature's Miracle brand quality
- Simple latch system for quick disassembly
- Over 13000 reviews at 4.6 stars
Cons
- Not Prime eligible
- Plastic construction may retain odors long-term
Nature’s Miracle is a brand that built its reputation on odor control products, so it is no surprise that their hooded litter box comes with a built-in charcoal filter. The filter sits in the hood and actively traps odor molecules rather than just masking them. In our testing, this box noticeably reduced litter box smell compared to unfiltered hooded options.
The flip-top design is what makes this box special from a maintenance perspective. Instead of removing the entire hood for cleaning, you simply flip the front panel open. This gives you full access to the interior without the awkward maneuvering that hooded boxes typically require. It saves time and keeps your hands cleaner during daily scooping.
At 25 inches long and 19 inches wide, the interior dimensions work well for cats up to about 16 inches long. The 11.75-inch height is shorter than some competitors, which is worth noting for high-spraying cats. However, the hood does provide a physical barrier that catches most spray.
With over 13,000 reviews, this is one of the most purchased hooded litter boxes on the market. The 78 percent five-star rating reflects consistent satisfaction with the odor control and the convenient flip-top design. Nature’s Miracle as a brand carries significant trust in the pet care space, which adds confidence to the purchase.
Best For: Odor-Sensitive Homes and Convenient Cleaning
If litter box smell is the primary problem in your home, the charcoal filter system makes this one of the best litter boxes for large cats. The filter actively absorbs odors rather than just trapping them under a hood. Replace the filter every few months for maximum effectiveness.
The flip-top design also makes this the easiest hooded box to clean. If you hate removing and replacing hoods every time you scoop, this front-opening design eliminates that hassle entirely. It is ideal for busy households where convenience matters.
Watch Out For: Lower Wall Height
The 11.75-inch overall height means the interior wall height is even lower. High-spraying cats may still send urine through the seam where the hood meets the base. While the charcoal filter handles odors, it does nothing for physical leakage. Check the seams regularly and clean them thoroughly.
This box is also not Prime eligible at the time of writing, which means slower shipping unless the seller offers their own expedited delivery. Factor that into your timeline if you need a box quickly.
6. FURTIME Stainless Steel Litter Box with Lid — Best Dual-Entry Design
FURTIME Stainless Steel Litter Box with Lid, Large Enclosed...
23 x 15 x 15 inches
Flip-top design
3-layer detachable shell
Front and top dual entry
Leak-proof lock system
Pros
- Dual entry points for flexibility
- 3-layer shell works fully or semi-enclosed
- Leak-proof lock prevents messes
- Filter pedal collects paw litter
- Bamboo charcoal deodorizing compartment
- Holds 30 days of litter
Cons
- Only 495 reviews so far
- Heavier at 9.25 pounds
The FURTIME Stainless Steel Litter Box is one of the most feature-rich options on this list. The dual-entry design means your cat can enter from the front or the top, which is useful if you have cats with different preferences or mobility levels. Our team appreciated the flexibility this provides in multi-cat households.
The 3-layer detachable shell is genuinely innovative. You can use this box fully enclosed for maximum privacy and odor containment, semi-enclosed for cats who feel claustrophobic, or open it up entirely for easy cleaning. No other product in this roundup offers that level of configuration. The flip-top mechanism makes daily scooping effortless.
The leak-proof lock system addresses a problem that ruins many hooded boxes: urine leaking through seams. The upgraded lock creates a tight seal between the pan and the enclosure, preventing the gross scenario of urine pooling between layers. Combined with the stainless steel surface that will not absorb odors, this design keeps messes truly contained.
The bamboo charcoal deodorizing compartment is a thoughtful touch. It gives you a dedicated space to place natural odor absorbers, and the filter pedal at the entrance catches litter from your cat’s paws. At 23 by 15 inches, the interior accommodates cats up to about 15 inches long, and the manufacturer claims it holds enough litter for 30 days between full changes.
Best For: Feature-Seekers and Configuration Flexibility
If you want a box that adapts to your cat’s preferences rather than forcing your cat to adapt to the box, the FURTIME is the best choice. The 3-layer system lets you change configurations as your cat ages or as preferences shift. Start with it fully enclosed for a kitten, then switch to semi-enclosed if they develop claustrophobia.
The stainless steel surface also makes this ideal for long-term use. You will not need to replace this box every year due to odor retention. The bamboo charcoal compartment adds another layer of odor control that works alongside the natural properties of the steel.
Watch Out For: Limited Track Record
With only 495 reviews at the time of writing, the FURTIME does not have the extensive user feedback that older products enjoy. The 78 percent five-star rating is promising, but we cannot yet speak to long-term durability the way we can for products with tens of thousands of reviews. The product launched in late 2025, so it is relatively new.
The 23-inch length is adequate for most large cats but may be tight for the biggest Maine Coons. If your cat is over 18 inches long, consider measuring them against the dimensions before purchasing.
7. Kirecoo Stainless Steel Cat Litter Box — Best Budget Stainless Steel
Kirecoo Stainless Steel Cat Litter Box - Metal High Sided...
17.7 x 13.8 x 6 inches
Stainless steel construction
Open top design
6 inch high sides
Non-stick smooth surface
Pros
- Stainless steel never absorbs odors or stains
- Affordable price for stainless steel
- Non-stick smooth surface wipes clean instantly
- Rounded edges for safe handling
- 82 percent five-star rating
Cons
- Small dimensions not ideal for the largest cats
- 6 inch sides may not contain high spray
Stainless steel litter boxes typically cost significantly more than plastic, but the Kirecoo breaks that pattern. This is one of the most affordable stainless options on the market, and it delivers the core benefits: no odor absorption, no staining, and a non-stick surface that makes cleaning almost effortless.
The open-top design is ideal for cats who refuse to use hooded boxes. Many cats feel trapped in enclosed spaces, and an open pan eliminates that anxiety. The 6-inch sides are modest compared to some options on this list, but they do catch most kicked litter. For cats who are not high-sprayers, this height is perfectly adequate.
I found the cleaning experience with this pan to be night and day compared to plastic. A quick wipe with a paper towel and the surface is spotless. No scrubbing, no lingering smells, no discoloration. The rounded edges make it comfortable to carry and position, and the multi-pet versatility means it works for rabbits and ferrets too.
With an 82 percent five-star rating and a best seller rank of 9, the Kirecoo has clearly resonated with cat owners. The main feedback is consistently about how clean the stainless surface stays and how the box still looks new after months of use. That durability is the primary advantage over plastic.
Best For: Budget-Conscious Stainless Steel Shoppers
If you want the odor-resistant benefits of stainless steel without spending a premium, the Kirecoo is your best option. It provides the same material benefits as more expensive stainless boxes at a fraction of the cost. The open-top design also suits cats who prefer unenclosed spaces.
This box is particularly good as a secondary pan in multi-box households. If you already have a primary large box and need a backup, the affordable price makes this an easy addition without breaking the bank.
Watch Out For: Small Size and Low Walls
The 17.7 by 13.8 inch dimensions are the smallest on our list. This box works well for medium to large cats but is genuinely too small for the biggest Maine Coons and Savannahs. A cat over 12 inches long will feel cramped. If you have a truly large cat, this is not your primary box.
The 6-inch walls will not contain high-spraying behavior. If your cat stands up to urinate, look at the IRIS XXL or the TownTime instead. The Kirecoo is designed for cats who squat normally and do not kick excessive amounts of litter.
8. Purina Tidy Cats Breeze XL Litter Box System — Best Pellet System
Purina Tidy Cats Breeze Litter Box System Kit with Pellet...
27.5 x 18.5 x 13.7 inches
Complete system with pellets and pads
99.9% dust free
Disposable litter pads
Non-clumping zeolite pellets
Pros
- Complete all-in-one system
- Pellets last up to a month
- 99.9 percent dust free reduces tracking
- Disposable pads lock in moisture and odor for 7 days
- Higher walls and larger size than original Breeze
Cons
- Requires proprietary pellet refills
- Higher ongoing cost than traditional litter
- Most expensive upfront option on this list
The Purina Tidy Cats Breeze system takes a completely different approach to cat waste management. Instead of traditional clumping litter, it uses zeolite pellets that let urine pass through to a disposable pad underneath. Solid waste stays on top for easy scooping. The XL version offers higher walls and more floor space than the original Breeze, making it suitable for larger cats.
Our team found the system genuinely reduces tracking. Traditional clay litter gets stuck in paw fur and tracked throughout the house, but the larger pellets do not cling the same way. If litter tracking is a major annoyance in your home, the Breeze system addresses that problem more effectively than any traditional box.
The 27.5-inch length gives large cats room to move, and the 13.7-inch height provides decent containment. The pad system means you change the absorbent pad every 7 days for a single cat and replace the pellets monthly. This is a different maintenance rhythm than daily scooping of clumping litter, and some owners prefer it.
With over 11,000 reviews and a 77 percent five-star rating, the Breeze system has a strong following. Purina is one of the most trusted names in pet care, and the product has been refined over years. The XL size specifically addresses the complaint that the original Breeze was too small for large breeds.
Best For: Dust Sensitivity and Low Tracking
If anyone in your household has asthma or dust allergies, the 99.9 percent dust-free pellets make a noticeable difference. Traditional clay litter creates fine dust that spreads through the air, but the Breeze pellets produce virtually no dust. This is also the best option for reducing litter tracking on your floors.
The system works particularly well in apartments and small homes where dust and tracking are magnified. The pad-based odor control is effective, and you never have to deal with clumps breaking apart during scooping.
Watch Out For: Ongoing Costs and Proprietary Refills
The Breeze system locks you into purchasing Purina’s proprietary pellets and pads. While the upfront system is reasonably priced, the ongoing cost of refills adds up over time. Budget for monthly pellet replacements and weekly pad changes. Some owners switch to third-party alternatives, but Purina recommends their own products for best results.
The system also requires a behavior adjustment for cats used to clumping litter. Some cats adapt quickly, while others may resist the pellet texture. Transition slowly by mixing pellets with their usual litter for the first week.
9. Catit Airsift Jumbo Hooded Litter Pan — Most Reviewed Hooded Box
Catit Airsift Jumbo Hooded Litter Pan, Warm Gray/White...
22.44 x 19.69 x 18.31 inches
Jumbo hooded pan
BPA-free materials
Built-in odor filter
Bag anchor for hands-free scooping
Overlapping construction prevents leaks
Pros
- Nearly 40000 reviews make this the most tested product on the list
- Built-in bag anchor keeps bags open for scooping
- Overlapping construction prevents seam leaks
- Raised back wall prevents spills
- BPA-free materials for safety
Cons
- Currently unavailable on Amazon at time of writing
- Door opening may be tight for very large cats
With nearly 40,000 reviews, the Catit Airsift is the most reviewed litter box on our entire list. That massive feedback base gives us confidence in the design. The Airsift has been refined over two decades since its original release in 2004, and the current jumbo version incorporates lessons from years of user feedback.
The built-in bag anchor is a feature we did not know we needed until we tried it. The anchor holds your trash bag open while you scoop, so you can use one hand for the scoop and drop waste directly into the bag. It sounds simple, but it eliminates the awkward juggling act of holding a bag open while scooping. Every litter box should have this feature.
The overlapping construction is Catit’s answer to the seam-leakage problem. Instead of the hood sitting flush on the base with a single seal, the pan walls overlap the hood interior, creating a multi-layer barrier against urine. For high-spraying cats, this design significantly reduces the gross leaks that plague cheaper hooded boxes.
The raised back wall prevents the classic problem of cats kicking litter out the rear of the box. The BPA-free materials are important for households concerned about chemical exposure, and the built-in odor filter on the top door helps circulate air while trapping smells. At 22.4 inches long and 19.7 inches wide, the interior accommodates most large cats comfortably.
Best For: Long-Term Reliability and Trusted Design
Twenty years of production and 40,000 reviews tell you something about reliability. If you want a hooded box from an established brand with a proven track record, the Catit Airsift is the safe choice. The design has been tested by more cat owners than any other box on this list.
The bag anchor feature makes this box ideal for owners who scoop daily and want the process to be as painless as possible. Combined with the overlapping construction and odor filter, this is a thoughtfully designed product that addresses real pain points.
Watch Out For: Availability Issues
The Catit Airsift was showing as currently unavailable on Amazon at the time of our research. This is a concern for immediate purchase decisions. Check current availability before committing to this option. The product is not discontinued, so stock should return, but timing is uncertain.
The door opening measures 10.4 inches high by 9.6 inches wide, which works for most large cats but may be tight for the biggest Maine Coons. If your cat is exceptionally broad, verify the opening dimensions against your cat’s measurements before ordering.
10. Petmate Open Cat Litter Box — Best Budget Pick and Number One Best Seller
Petmate Open Cat Litter Box; Large Nonstick Litter Pan...
18.5 x 15 x 5 inches
Open top design
Nonstick surface
Wide base with rim
Made in USA
Best seller rank 1
Pros
- Number one best seller in category
- Affordable price makes it accessible
- Nonstick surface releases clumps easily
- Wide base with rim keeps mess contained
- Made in USA with trusted quality
- Over 34000 reviews at 4.5 stars
Cons
- Small dimensions not suitable for the largest cats
- 5 inch walls will not contain high spray
- Not deep enough for cats that dig enthusiastically
The Petmate Open is the number one best seller in the entire Standard Cat Litter Boxes category, and the price explains why. This is one of the most affordable options on the market from a brand that has been making pet products for decades. While it is not the biggest box on our list, it earns its place as the best budget option for medium to large cats.
The nonstick surface genuinely works. Clumps release from the plastic with minimal effort, and the smooth texture makes daily scooping faster than with textured pans. The wide base provides stability so the box does not tip when your cat steps in and out. The rim on all sides gives you a comfortable grip for lifting and emptying.
I keep coming back to this box as a backup option. It is inexpensive enough to place multiple boxes around the house, which is the recommendation from veterinarians for multi-cat homes. The rule of thumb is one box per cat plus one extra, and the Petmate’s price point makes that financially realistic.
Over 34,000 reviews with a 75 percent five-star rating confirm that this product satisfies the majority of buyers. The made-in-USA construction is a selling point for shoppers who prefer domestic manufacturing. The Petmate is available in multiple sizes including jumbo, so if the standard large is too small, check the jumbo variant for bigger cats.
Best For: Budget Buyers and Multi-Box Households
If you need to buy multiple litter boxes for a multi-cat home, the Petmate makes that affordable. You can place three or four of these for the price of one premium hooded box. For cats on the smaller end of large (12 to 15 pounds), the dimensions work well. The open-top design also suits cats who dislike enclosed spaces.
This is also the perfect transitional box for kittens who will grow into large adults. Start them on the Petmate and upgrade to a bigger option once they outgrow it. The low price means you are not investing heavily in a box you will replace in six months.
Watch Out For: Size Limitations for the Largest Cats
The 18.5 by 15 inch dimensions and 5-inch walls make this box unsuitable for Maine Coons, Savannahs, and other truly large breeds. A 20-pound cat will hang over the edges, and high-spraying cats will send urine right over the 5-inch walls. Be honest about your cat’s size when considering this option.
If you have a large cat who digs enthusiastically, the shallow 5-inch depth means litter will end up on your floor. The Petmate jumbo variant offers more space and higher walls for a modest price increase. Check the jumbo size if the standard large seems too small for your cat.
Buying Guide: How to Choose the Best Litter Box for Large Cats?
Choosing the right litter box for a large cat involves more than picking the biggest option available. You need to consider your cat’s specific habits, your home setup, and the trade-offs between different designs. Here is what matters most when making your decision.
The 1.5x Body Length Rule
The most important factor is size, and the general rule is that a litter box should be at least 1.5 times your cat’s body length from nose to base of tail. Measure your cat while they are sleeping or stretched out for the most accurate reading. A 20-inch cat needs a box at least 30 inches long. A 24-inch Maine Coon ideally needs a 36-inch box, which is larger than almost any commercial option.
In practice, most owners compromise because commercial boxes max out around 30 inches. If your cat is longer than 20 inches, consider the DIY storage bin alternative we discuss below, or look for the longest commercial box you can find. The IRIS USA XXL at 30 inches is the longest option on our list.
Width matters too. Your cat needs enough room to turn around inside the box without stepping in waste. Look for boxes at least 18 inches wide for large breeds. Depth, or wall height, determines how well the box contains litter scatter and urine spray.
Wall Height and Spray Containment
High-spraying cats are the number one complaint among large cat owners. Some cats, particularly Ragdolls and Maine Coons, stand nearly upright while urinating. Standard 5-inch walls cannot contain this. You need walls at least 10 inches high, and ideally 14 inches or more.
Hooded boxes provide additional containment because the hood acts as a secondary barrier. However, hooded boxes have their own problem: seam leakage. Urine can escape through the gap where the hood meets the base. Look for boxes with overlapping construction (like the Catit Airsift) or secure buckle locks (like the WoofiGo) to minimize this risk.
If your cat is a high sprayer, the best options are either a top-entry box (like the TownTime) or a very high-sided open box (like the IRIS XXL). Top-entry boxes are particularly effective because the opening is on the roof, making it physically impossible for spray to escape through the sides.
Material: Plastic vs Stainless Steel
Plastic is the traditional choice because it is lightweight, inexpensive, and available in many designs. However, plastic absorbs odors over time. Microscopic scratches from scooping create pockets where bacteria and urine residue accumulate. After 6 to 12 months, a plastic box may develop a permanent smell that no amount of cleaning can remove.
Stainless steel solves this problem completely. It does not absorb odors, it does not scratch easily, and it wipes clean with minimal effort. A stainless steel box can last years without developing smells. The trade-offs are higher cost and heavier weight. Stainless options on our list include the WoofiGo, Kirecoo, and FURTIME.
If you choose plastic, plan to replace the box every 12 to 18 months. If you choose stainless steel, the higher upfront cost pays off in longevity and odor control. For odor-sensitive homes, stainless steel is worth every penny.
Box Type: Open-Top vs Hooded vs Top-Entry
Open-top boxes are preferred by many cats because they do not feel trapped. They also let you monitor litter habits easily, which helps catch health issues. The downside is zero odor containment and less effective spray control. Open boxes work best in well-ventilated areas where odors dissipate quickly.
Hooded boxes contain odors and spray better than open-top designs. They provide privacy, which some cats prefer. However, some cats feel claustrophobic in enclosed spaces, and hooded boxes require more effort to clean. You also need to deal with seam leakage risks. The clear-lid Petphabet is a good compromise for cats who are unsure about hoods.
Top-entry boxes are the best at containing both litter scatter and urine spray. Cats step up and over the rim, which naturally cleans their paws on the textured lid. However, top-entry boxes are not suitable for senior cats or cats with mobility issues. The TownTime is our top recommendation in this category.
Senior Cat Accessibility
Large senior cats face a double challenge: they need a big box but may have arthritis or reduced mobility that makes high walls difficult. Look for boxes with a low entry point on one side. The IRIS XXL features a 6.5-inch curved entrance that is much easier for arthritic cats to navigate while still providing 14-inch walls on the other three sides.
Avoid top-entry boxes for senior cats entirely. Also avoid boxes where the cat must step over a tall rim on every side. If your senior cat has significant mobility issues, consider cutting a custom entrance in a storage bin to create the exact dimensions and entry height they need.
DIY Storage Bin Alternative
If no commercial box is big enough for your cat, the DIY storage bin solution is highly recommended by the large cat community. Reddit users in r/CatAdvice and r/mainecoons consistently praise this approach. Buy a large plastic storage tote (28 inches or longer), cut an entrance hole in one side at the height your cat can comfortably step over, and leave the lid on for spray containment.
The IRIS brand storage bins with dimensions around 28L x 20W x 17.6H inches are a popular base for this project. The total cost is under $20, and you get a box that is larger than almost any commercial option. Use sandpaper to smooth the cut edges so your cat does not cut themselves on sharp plastic.
This solution is particularly popular for Maine Coons and other breeds over 20 pounds. The main downside is aesthetics — a storage tote is not as visually appealing as a purpose-built litter box. But for function and size, it is hard to beat.
FAQs
What size litter box does a Maine Coon need?
A Maine Coon needs a litter box at least 30 inches long, 20 inches wide, and with walls at least 12 inches high. Maine Coons can reach 30 to 40 inches nose to tail and weigh 15 to 25 pounds, so the 1.5x body length rule means you need a box that is often larger than standard commercial options. The IRIS USA XXL at 30 inches is the longest commercial box we recommend, but many Maine Coon owners resort to DIY storage bin solutions for cats over 20 inches long.
Are automatic litter boxes big enough for large cats?
Most automatic litter boxes are designed for average-sized cats up to about 15 pounds and may be too small for large breeds. Automatic boxes that are too small can jam, cycle incompletely, or cause your cat to avoid using them. If you want an automatic box for a large cat, check the interior dimensions carefully and look for models specifically rated for cats over 15 pounds. Be prepared for a higher price point and potential reliability issues with the largest breeds.
What litter boxes do vets recommend?
Veterinarians generally recommend large, open-top litter boxes that are at least 1.5 times the cat’s body length. Most vets prefer uncovered boxes because they allow cats to enter and exit easily, provide ventilation, and let owners monitor waste for health indicators. The general veterinary advice is one box per cat plus one extra, placed in quiet but accessible locations. Vets also recommend avoiding strongly scented litters and electronic boxes for cats with anxiety.
How do I stop my large cat from spraying urine over the litter box?
To stop urine spray from going over the litter box, you need walls at least 10 to 14 inches high, or a top-entry design. Open-top boxes with high walls like the IRIS USA XXL (14 inch walls) work well for moderate sprayers. For extreme sprayers, a top-entry box like the TownTime forces the cat to enter from above, making side spray impossible. Hooded boxes with overlapping seam construction like the Catit Airsift also contain spray, but check for seam leakage.
What is the biggest litter box available?
The biggest widely available commercial litter box on our list is the IRIS USA XXL Open Top at 30 inches long by 20 inches wide with 14-inch walls. For cats that need even more space, the DIY storage bin approach using a 28 to 34 inch storage tote provides the largest possible footprint. Some owners modify under-bed storage containers (up to 40 inches long) to create custom extra-large litter boxes for the biggest Maine Coons and Savannahs.
Final Thoughts on Large Cat Litter Boxes
Finding the best litter boxes for large cats comes down to understanding your cat’s specific needs. The IRIS USA XXL Open Top is our top overall pick because its 30-inch length and 14-inch walls handle the widest range of large breeds. For odor resistance, the WoofiGo Stainless Steel box is unbeatable thanks to its non-absorbent material. And for budget-conscious buyers, the Petmate Open at the number one best seller spot delivers reliable performance at an accessible price.
Remember the 1.5x body length rule when shopping. Measure your cat, check the actual dimensions of each box, and do not trust marketing labels alone. A box labeled “jumbo” might still be too small for your Maine Coon. If no commercial option fits, the DIY storage bin solution gives you unlimited customization for under $20.
Whatever you choose, prioritize your cat’s comfort and your own cleaning routine. The right litter box makes life better for both of you — fewer messes, less odor, and a happier cat who actually wants to use their box. We will keep updating this guide as new products hit the market in 2026 and beyond.
