The best cat litter box x large for most cats needing more room to turn is the IRIS USA XX-Large High Sided Cat Litter, with a 30 x 20 in footprint and open top. For privacy, choose the Amazon Basics hooded box; for a lidded steel option, consider ICYAIR.

The label “large” varies, so compare floor dimensions first. A box can have tall walls or a hood and still leave less room for a big cat to turn than a wider open pan.

If you want a broader starting point, see our best cat litter box guide. We compared conventional open, covered and steel boxes for cats that need more room, with entry style and cleaning access in mind.

How we chose extra large cat litter boxes

The most useful extra large litter box gives a cat enough clear floor area to turn, dig and settle without crowding. We compared stated dimensions, entry styles, wall height, material and included accessories.

Our score weighs specs, features and buyer feedback against what you're shopping for. A higher score means a closer fit for this search, while individual cats may prefer different entry styles or materials.

The products below are ordered by score, but the top score is not automatically the best fit for every home. Measure the available floor area, doorway and route for carrying a full box before you choose.

Compare extra large cat litter box sizes and entry styles

The IRIS USA XX-Large box has the broadest stated footprint here, while the covered choices trade some open access for a more enclosed space. Use the comparison to narrow down size, entry and material.

The best choice depends on whether your cat prefers an open pan, a hood or a steel surface. Each pick below addresses a different combination of room, access and mess control.

Amazon Basics No-Mess Hooded Enclosed Cat Litter: Best for a private enclosed space

9.7/10Our score

• 23.62 x 17.32 x 16.93 in
• Swinging door
• Pre-installed carbon filter
• Built-in handle

An enclosed design gives cats privacy, while the swinging door and pre-installed carbon filter add convenience. Check the interior space if your cat needs substantial room to turn.

See it on Amazon

Pros

• Enclosed design
• Carbon filter included
• Snaps into place for scooping

Cons

• Less open turning space than an uncovered pan
• Door may not suit cats that avoid flaps

The Amazon Basics No-Mess Hooded Enclosed Cat Litter suits cats that already use a hooded box and benefit from a private space. Its outer dimensions are 23.62 x 17.32 x 16.93 in, with a swinging door and built-in handle.

A pre-installed carbon filter is included for odor control, and replacement filters are sold separately. The hood snaps into place, which can make access for scooping or changing litter more straightforward.

This is a covered choice, so the outside measurements don't tell you exactly how much turning room the cat has inside. If your cat is long or tends to circle before settling, compare the interior space before deciding.

Choose this Amazon Basics box when an enclosed style is already familiar to your cat. If you want a bigger covered option, compare our best jumbo covered cat litter box guide.

Amazon Basics Large Cat Litter Box: Best for easy open access

9.6/10Our score

• 19 x 15 x 11.75 in
• Open top
• High sides
• Lowered front entry

The open top makes scooping and monitoring simple, with high walls and a lowered front. Its stated footprint is more modest than the extra-large picks.

See it on Amazon

Pros

• Open top is easy to monitor
• Lower front entry
• Scoop stores on the box

Cons

• Smaller footprint than several picks here
• Plastic rather than steel

The Amazon Basics Large Cat Litter Box offers a simple open top and high sides, with a lowered front to ease entry. Its dimensions are 19 x 15 x 11.75 in, so it fits homes that need a modestly larger pan without the footprint of the biggest options here.

Because the top is open, you can see the litter and scoop without removing a hood. The included scoop stores on the box, keeping it close to the cleanup area.

This is a useful step up from a small tray, but its 19 x 15 in footprint is not as roomy as the 30 x 20 in IRIS USA option. Measure the cat's turning space rather than relying on the word “large.”

Pick it for easy access and straightforward monitoring, especially if a very broad pan won't fit your room. For more ways to compare sizes and styles, see our best cat litter boxes.

3

Kirecoo Large High Sided Stainless Steel Cat: Best for a compact steel pan

9.5/10Our score

• 17.7 x 13.8 x 6 in
• Stainless steel
• Open top
• Rounded edges

This open stainless steel pan has rounded edges and a smooth surface. Its footprint is compact, so measure your cat and available space before treating it as an extra-large choice.

See it on Amazon

Pros

• Stainless steel surface
• Open design
• Rounded edges

Cons

• Smaller footprint than most picks here
• Sides are 6 in high

The Kirecoo Large High Sided Stainless Steel Cat Litter is an open steel pan with rounded edges and a smooth surface. At 17.7 x 13.8 x 6 in, it is one of the smaller choices here, so it suits buyers prioritizing material and easy wiping over a very broad floor area.

Kirecoo describes the stainless steel as non-porous and says waste is less likely to stick to the smooth surface. The 6 in sides are lower than the tall-wall picks, which may make stepping in easier for some cats.

The compact size is the key trade-off. A cat that needs substantial room to turn may do better in a wider pan, even if that means choosing plastic.

Choose Kirecoo for an open steel pan in a tight space, then check the dimensions against your cat before buying. Keep litter supplies nearby in a container from our best cat litter storage guide.

4

IRIS USA XX-Large High Sided Cat Litter: Best for roomy open turning space

9.4/10Our score

• 30 x 20 x 14 in
• 14 in walls
• 6.5 in curved entrance
• Open top

A 30 x 20 in footprint gives large cats room to turn, dig and stretch. The open top and curved entrance pair access with high walls.

See it on Amazon

Pros

• Largest stated floor footprint here
• High walls help contain scatter
• Open top is easy to monitor

Cons

• Needs substantial floor space
• Tall walls may not suit every cat

The IRIS USA XX-Large High Sided Cat Litter is the strongest fit when your priority is open turning room. Its 30 x 20 in footprint gives more floor area than the other listed boxes, and 14 in walls help contain litter and spray.

The curved entrance is 6.5 in high, creating a lower way into the tall-sided pan. The open top also makes it easy to monitor litter habits and reach inside for scooping.

This box needs real floor space, so measure the intended spot and the path through your home before bringing it in. The tall walls may also be a poor match for a cat that avoids stepping over a raised entry.

For a younger cat who needs an easier step, see our litter boxes for kittens guide.

Choose it for large cats that prefer an open box and have room for a broad footprint. If automatic cleaning is also on your mind, first read do automatic cat litter boxes really work? to compare the trade-offs.

IRIS USA Large Front Door Cat Litter: Best for covered front entry

9.2/10Our score

• 21 x 18.75 x 17 in
• Front door
• Carrying handle
• Scoop with hook

The covered design has a front door and carrying handle. Its interior dimensions are smaller than the outer size, so compare the inside measurements with your cat.

See it on Amazon

Pros

• Enclosed space
• Carrying handle and buckles
• Scoop hooks under the hood

Cons

• Interior is 15.25 x 14 x 15.5 in
• Designed for small to medium cats

The IRIS USA Large Front Door Cat Litter offers an enclosed setup with a front flap, carrying handle and buckles. Its outer size is 21 x 18.75 x 17 in, while the interior measures 15.25 x 14 x 15.5 in.

That difference between outside and inside measurements matters for bigger cats. The 9.25 x 9 in door opening is also worth checking if your cat is hesitant around flaps or needs a wide entrance.

A scoop hooks under the hood for storage. The maker describes this box as sized for small to medium cats, so it's a more cautious pick for a genuinely extra-large cat.

Choose it when a covered box and front-door entry are more important than maximum turning room. For another option that keeps the box portable for trips, see our best portable kitty litter box guide.

KISENG Stainless Steel Cat Litter Box: Best for steel with a high fence

9.0/10Our score

• 22.83 x 14.96 x 10.24 in
• Stainless steel pan
• High ABS fence
• Scoop and anti-slip pedal mat

The stainless steel pan has a high ABS fence, and the kit includes a scoop and anti-slip pedal mat. Its narrow width may matter for cats that turn in a wide circle.

See it on Amazon

Pros

• Steel pan with removable-style fence design
• Scoop and pedal mat included
• Roomier than compact pans

Cons

• Narrower than several picks here
• Fence material is ABS

The KISENG Stainless Steel Cat Litter Box combines a steel pan with a high ABS fence. Its stated dimensions are 22.83 x 14.96 x 10.24 in, with a scoop and anti-slip pedal mat included.

The fence may help catch kicked litter and splashes, while the open pan makes the interior visible. Stainless steel is the main draw for buyers who want a smooth surface instead of a plastic tray.

The width is under 15 in, which can feel narrow for a cat that turns in a wide circle. Measure the clear floor area inside the fence and compare it with how your cat moves in its current box.

Choose it if you want a steel pan with a fence and accessory kit. For a less conventional layout, use our guide to choosing a large corner litter box.

So Phresh by Petco Scatter Shield High-Back: Best for a step-in front

8.7/10Our score

• 24 x 18 x 24 in stated dimensions
• High back
• Step-in front
• 50% recycled materials

A high back and step-in entrance suit cats that prefer an open pan with a raised rear wall. The stated height is 24 in, so check the overall fit for your space.

See it on Amazon

Pros

• Step-in front
• High back helps contain scatter
• Made of 50% recycled materials

Cons

• Overall height is listed as 24 in
• Open front offers less privacy

The So Phresh by Petco Scatter Shield High-Back is an open plastic pan with a step-in entrance and raised rear wall. Its stated footprint is 24 x 18 in, which offers a broad base without a hood.

The high back is intended to help contain litter scatter and spray. The box is made with 50% recycled materials, and the front entrance leaves the top open for access.

The dimensions also give a 24 in height, unusually tall for an open pan. Check the full shape and where the high back sits to make sure it fits beneath nearby shelves or in its intended corner.

Choose it for a step-in front and a raised back, while confirming its overall fit at home. If your cat scratches nearby surfaces after using the box, see our best cat scratching post for large cats.

8

ICYAIR XXL Stainless Steel Litter: Best for an extra-wide steel box

8.5/10Our score

• 28 x 20 x 12 in
• Stainless steel
• Lid and footboard
• Scoop included

The 28 x 20 in size offers broad floor space, with a lid, footboard and scoop. Measure carefully because this box needs more room than a standard pan.

See it on Amazon

Pros

• Broad 28 x 20 in footprint
• Lid and footboard included
• Stainless steel bottom

Cons

• Requires ample floor space
• Heavier than plastic options

The ICYAIR XXL Stainless Steel Litter offers a broad 28 x 20 in footprint, stainless steel base, lid and footboard. It is one of the roomiest options here, but its size needs careful planning in a small bathroom or laundry area.

The included scoop and footboard make this a more complete setup out of the box. Its 12 in walls and lid form a more enclosed arrangement than a basic open steel tray.

Measure the space with the lid in place and allow enough room for your cat to enter and turn. The roomy floor area is useful only if the finished setup fits your home and your cat accepts the enclosure.

Choose ICYAIR when you want steel and a lid with a large footprint. If you are considering a self-cleaning model instead, read how quiet self cleaning litter boxes are before weighing noise and space.

MIXJOY Stainless Steel Litter Box: Best for a lidded steel setup

8.3/10Our score

• 23 x 15 x 11 in
• Stainless steel
• Lid with locking buckle
• Scoop included

A locking lid and stainless steel base make this a lidded option for buyers who want a smaller footprint than the 28 x 20 in box. Its 23 x 15 in size may not suit every large cat.

See it on Amazon

Pros

• Lid connects with a locking buckle
• Scoop included
• Stainless steel base

Cons

• Narrower than the largest picks
• Lid adds height to the setup

The MIXJOY Stainless Steel Litter Box pairs a steel base with a lid and locking buckle. Its 23 x 15 x 11 in dimensions make it more compact than the largest boxes here, while still offering high sides.

MIXJOY includes a scoop and describes an overlap design intended to keep urine inside the box. The lid creates a more enclosed setup, so consider whether your cat is comfortable using a covered space.

The 15 in width is the main size limit for cats that need a lot of room to turn. Compare that interior space with your cat's current box before choosing it for an extra-large breed.

Choose MIXJOY for a lidded steel setup where a 23 x 15 in footprint works. If tracking is the bigger concern, pair a suitable box with a mat and compare options in our litter access and care guide.

What should you measure before choosing an XL cat litter box?

Measure the floor space your cat can use, not just the box's outer length and width. For a covered model, check the interior dimensions and the door opening because the hood can reduce usable room.

Also measure the route into the room, including narrow doorways and turns. A 30 x 20 in pan may fit the room but be awkward to carry through a tight hall.

The entry matters as much as the pan. A low or curved opening can help a cat step in, while a swinging flap or tall wall may be unfamiliar or difficult for some cats.

Is an open or covered x-large cat litter box better?

An open box usually gives more direct access and makes scooping easy, while a covered box gives a more private space and can contain visible scatter. The better style is the one your cat will enter comfortably and that fits your cleaning routine.

For a large cat, open boxes also make it easier to compare usable floor space. A covered box may look large outside yet feel restrictive inside, so look for interior dimensions where available.

If your cat already uses a hood, a covered model may be the simpler change. If they avoid flaps or enclosed spaces, an open high-sided box is a safer style to consider.

Does stainless steel make a better XL litter pan?

Stainless steel can be appealing if you want a smooth pan that is easy to wipe, but size and entry still come first. The steel options here range from compact Kirecoo and KISENG pans to ICYAIR's wider 28 x 20 in setup.

A steel box can also be heavier than a basic plastic tray, especially when filled. Think about where you'll empty it and whether you need to lift it often.

Choose material after confirming the usable area. A steel pan that is too narrow won't solve a cat's need for more room to turn.

How do you keep a large litter box manageable?

Place the box where your cat can reach it without obstacles, then leave enough clearance for you to scoop it. A large footprint can make a cramped corner harder to clean around.

Use a litter mat only if it does not narrow the entrance or make stepping in harder. Keep spare litter in a sealed, easy-to-reach container, and scoop on a schedule that suits the number of cats using the box.

For a roomy open setup, the IRIS USA XX-Large is the clearest choice because of its 30 x 20 in base. Pick Amazon Basics for a familiar hooded format, or ICYAIR if you want a lidded steel box with a broad footprint.

Frequently asked questions

How large should a litter box be for a big cat?

Choose a box that lets your cat enter, turn around and dig without pressing against the walls. Compare the usable floor area with your cat's body length and turning style, then account for any hood or fence that reduces the open area.

A 30 x 20 in pan offers more floor space than a 19 x 15 in pan.

Are open or covered extra large litter boxes better?

Open boxes give you a clear view for scooping and monitoring, while covered boxes offer a more private space and can help contain litter. Your cat's comfort with a hood or door matters as much as the outside dimensions.

Measure the interior of covered boxes because their outer size can overstate the usable room.

Do high sides make a litter box easier to use?

High sides can help keep kicked litter and spray inside the box, but the entrance still needs to work for your cat. Look for a lowered or curved entry if your cat struggles to step over tall walls.

Check entry height along with total wall height before choosing.

Will a stainless steel litter box fit a large cat?

Material alone doesn't determine fit; compare the pan's length and width with your cat's turning space. Some steel pans here are narrower than the largest plastic option.

A smooth steel surface may be easier to wipe, but choose by usable dimensions first.

Can two cats share one extra large litter box?

A larger pan gives more room, but it doesn't guarantee that two cats will comfortably share one box. Consider each cat's habits, access and willingness to use the same spot.

For a shared home, keep the box easy to reach and maintain, and provide separate options if either cat avoids it.
