Shopping for the best litter boxes for large cats gets weirdly frustrating, fast. “Large” often just means “slightly bigger than average,” which doesn’t help when your cat needs actual elbow room (or… paw room?).
And sure, some cats are naturally big, like Maine Coons, Ragdolls, Jamey’s Milo. Others just… grew into it. (Look, chonk happens.) Either way, if your cat has ever tried to use a too-small box and ended up half in, half out like they’re making a point, you already know the struggle.
This guide is for those cats. The big ones, the solid ones, the “how are you both graceful and somehow taking up this much space” types. We’re covering everything from automatic litter boxes to open-top options to traditional setups that actually give them room to do their thing—without turning your floor into a side project.

What to Look for in a Litter Box for Large Cats
Not all “large” litter boxes are created equal. Some are just slightly bigger with better marketing.
Here’s what actually matters:
Now let’s check out my favorite options for our XL (and XXL) kitties.
Litter-Robot 5 Pro — Best Automatic Litter Box
If you want the “never scoop again” lifestyle (and honestly, who doesn’t), this is the top-tier option right now.
Top Features
- Supports cats up to 30 lbs
- Fully automatic waste sifting after each use
- AI-powered dual cameras with tracking
- WasteID™ distinguishes #1 vs #2
- Tracks weight and litter box visits
- Works for multi-cat homes (up to 5 cats)
Pros and Cons at a Glance
What We Like
This is one of the few automatic litter boxes that actually feels designed with big cats in mind. That 30-pound capacity matters more than you think, especially if you’ve got a long-bodied cat who technically fits into smaller boxes but clearly hates it.
The interior space is generous enough that your cat can turn around without doing that awkward half-pivot shuffle (you know the one). And for multi-cat homes, it handles traffic really well without turning into a disaster zone by day two.
The tracking features are also surprisingly useful. Not in a gimmicky way, but in a “wait, this is actually helpful” way, especially if you’re keeping an eye on health changes.

What to Consider
It’s a big investment, both in price and space. Also, some cats need a little transition period before they fully trust it (understandable, honestly).

HomerunPet Self-Cleaning Litter Box CS106 — Best Runner-Up Automatic
The HomerunPet Self-Cleaning Litter Box CS106 is an extremely close runner-up, especially for XL breeds like the Maine Coon.
Top Features
- 106L dome (huge interior space)
- Supports cats up to 25 lbs
- 12L waste bin (up to 20 days hands-free)
- Auto-refill litter system
- Wide entrance for easy access
- Triple-layer safety protection
Pros and Cons at a Glance
What We Like
This thing is big in the way you actually want it to be. The dome design gives cats plenty of room to move naturally, which is especially helpful for larger breeds that hate feeling boxed in.
The auto-refill system is a nice touch (and one of those features you don’t realize you want until you have it). It keeps the litter level consistent without you thinking about it, which helps with both cleanliness and cat acceptance.
Also worth noting: the wide entrance. Some large cats don’t love squeezing into tight openings, and this avoids that entirely.
What to Consider
It tops out at 25 pounds, so if you’ve got a truly massive cat, the Litter-Robot still has the edge. Otherwise, this is about as close as it gets to a tie.

PetSafe Multi-Cat Litter Box — Best Open-Top Box Style
Sometimes simple is better. Especially if your cat has strong opinions about enclosed spaces (and many do).
Top Features
- Extra-large open design
- Includes metal scoop
- Built-in waste compartment
- Rubber-sealed lid for odor control
- Works with multiple litter types
Pros and Cons at a Glance
What We Like
This is one of those “why don’t more boxes do this?” designs. The built-in waste compartment means you’re not walking back and forth to the trash every time you scoop (small thing, big difference).
The size is generous enough for larger cats to actually feel comfortable, and the open-top design keeps things accessible, especially for cats that refuse anything with a lid.
What to Consider
You’re still scooping, so this isn’t a low-maintenance option. Also, open-top means less containment for enthusiastic diggers.

The ergonomically-designed handle helps you maintain a comfortable grip during cleanup.
IRIS Open Top Cat XXL Litter Box — Best Open Traditional
Big, simple, and surprisingly well-designed.
Top Features
- Jumbo size (30 x 20 inches)
- High walls with scatter shield
- Low entry for easy access
- Durable BPA-free plastic
- Open-top for visibility
Pros and Cons at a Glance
What We Like
This hits that sweet spot between “basic” and “actually thoughtful.” The high sides and shield do a solid job containing litter (not perfectly, but enough to notice the difference).
The low front entry is also a nice touch, especially for older or less agile cats who still happen to be… large.
What to Consider
No frills here. If you want odor control or automation, you’ll need to look elsewhere.
This jumbo litter box is perfect for larger breeds like Maine Coons, Norwegian Forest Cats, Ragdolls, and Savannahs. The tall walls and three-sided shield help contain litter and spray, reducing the need for constant cleanups and minimizing waste.
Van Ness EZ Clean Enclosed Cat Litter Box — Best Covered Traditional
For cats who want privacy (and owners who want less smell drifting through the house).
Top Features
- Jumbo enclosed design
- Flip-top lid for easy cleaning
- Odor-control door and filter
- High sides for containment
- Durable, easy-clean surface
Pros and Cons at a Glance
What We Like
For a covered box, this one actually feels roomy instead of claustrophobic. The flip-top lid is a small detail that makes a big difference when you’re cleaning (no awkward lid juggling).
It also does a solid job containing both odors and litter scatter, which is a win if your cat tends to treat the litter box like a construction site.
What to Consider
Not every cat likes enclosed spaces. If your cat already avoids covered boxes, this probably won’t change their mind.
The Van Ness EZ Clean Enclosed Cat Litter Box offers spacious comfort for large kitties and easy maintenance for owners. Featuring a flip-top lid with an odor-control door, it helps contain odors while providing convenient access for cleaning. The high sides minimize litter scatter, and the polished finish resists stains and odors.
Final Thoughts
Large cats don’t just need a slightly bigger litter box, they need a different kind of setup entirely.
If you want convenience and don’t mind the price, the Litter-Robot 5 Pro and the HomerunPet Self-Cleaning Litter Box CS106 are pretty evenly matched for top contenders.
And if you prefer to keep things simple (or your cat does), the oversized traditional options still hold their own.
At the end of the day, the best litter box is the one your cat will actually use. Preferably without stepping halfway out of it like they’re testing your patience. (They are.)
