The Best Large Litter Box Enclosures

A large litter box enclosure only works if the box you already own fits inside it. Before you compare finishes, measure your litter box and check it against each cabinet’s listed interior size: an extra-large pan around 24 by 18 inches fits only a few of the picks below, while most double cabinets are built around boxes closer to 20 inches long.

This list draws on published specifications, independent reviews, and Amazon owner ratings. It covers two-room cabinets for two cats, a tall single cabinet for big cats, a fabric ottoman, and a rattan bench. For smaller pieces, see our litter box furniture picks.

This guide is general product information, not veterinary advice. If your cat’s litter box habits change, such as straining, going outside the box, or producing much more or less urine than usual, contact your veterinarian.

How to Choose a Large Litter Box Enclosure

Compare Interior Size, Not Outer Size

A 47-inch cabinet sounds huge, but if it is split into two rooms, each room is much smaller. Listed interior sizes on this list:

• Amunrbrek: 28.5 by 18.5 inches, 27.6 inches tall with the shelf removed
• ONBRILL: 22 by 18.5 inches per room, 18.9 inches tall
• Evermagin: 21.3 by 16.9 inches per room, 18.6 inches tall
• Homhedy: 19.5 by 18.3 inches per room, 16.8 inches tall

Zerbuger lists 30 by 20 by 20 inches for its ottoman and notes a 1 to 2-inch measuring tolerance. Leave a couple of inches around the box so you can slide it in and out to clean.

Room for a Big Cat

A 15 lb cat or a Maine Coon needs headroom to squat and space to turn. Height is where many cabinets fall short: a hooded or top-entry box inside a cabinet needs even more clearance. The Amunrbrek is the tallest inside, and its adjustable shelf can come out entirely to fit a top-entry box. Check your box’s height against the interior height before you order.

One Room or Two

A double litter box enclosure holds two boxes side by side, which suits a two-cat home with limited floor space. The Homhedy, ONBRILL, and Evermagin each have two rooms. A common rule of thumb is one box per cat plus one extra, so two cats sharing one double cabinet may still need a third box elsewhere.

Entry Side and Airflow

Check which side the cat enters from and whether you can change it. Amunrbrek’s 9.5 by 11.8-inch entrance installs on the left or right, SETVSON’s entrance can move to the other side, and Homhedy has a cat hole on each side. For odor, look for vents: Amunrbrek has a rear ventilation grille, ONBRILL has four small holes in the back, and SETVSON’s woven rattan lets air through.

Materials and Cleanup

Engineered wood cabinets like the Homhedy and Amunrbrek look like real furniture but can swell if urine sits on the surface, so keep a liner or mat inside and wipe spills quickly. Homhedy lists a water-resistant veneer. SETVSON uses PE rattan on a metal frame and Zerbuger is a polyester ottoman, both lighter to move. Double doors (Homhedy, ONBRILL, Evermagin) or a flip-up lid (Zerbuger) make daily scooping easier than a single side hole.

Weight and Assembly

The wooden cabinets are heavy: ONBRILL is listed at 67 pounds, Amunrbrek at 61.7, and Homhedy at 41.8, so plan where it goes before you build it. Amunrbrek estimates about 50 minutes of assembly. Zerbuger unfolds, and SETVSON’s frame is semi-prefabricated and foldable.

Who Should Look Elsewhere

If your cat is a senior with stiff joints or a kitten, a cabinet that adds a step or a narrow side hole can become a barrier. A low open pan from our best litter box picks is gentler. If you plan to put a self-cleaning box inside, most units here are too short; compare heights with the models in our self-cleaning litter box picks first.

A closed cabinet also makes it harder to see urine clumps. If your veterinarian wants you to watch your cat’s output, keep the box where you can check it easily.

Why You Should Trust Us

IndoorCatLab reviews gear for indoor cats independently. We do not conduct our own product trials; our picks draw on published specifications, independent reviews, and Amazon owner ratings, which also set each product’s ICL Score.

The ICL Score converts each product’s average Amazon owner rating to one 0 to 10 scale. Our ranking also weighs listed interior size, number of rooms, and entry design, so the order of the list is not the same as sorting by score. We may earn a commission from qualifying purchases, but that never affects a product’s ranking or score. Read the full method in How We Review, or browse all of our litter box coverage.

Final Thoughts

Best Overall: Amunrbrek Large Litter Box Enclosure Cabinet is the cabinet that actually fits a large box: its listed interior is 28.5 by 18.5 inches and 27.6 inches tall with the shelf removed, enough for an XL pan around 24 by 18 inches or a top-entry box. The entrance mounts on the left or right, and a rear grille adds ventilation.

Best Compact Double Cabinet: Homhedy 47.2″ Double-Door Cat Litter Box Enclosure gives two cats their own room with a cat hole on each side, double doors for scooping, and a water-resistant veneer. Each room is 19.5 by 18.3 inches inside, so it fits standard pans, not an XL box around 24 inches long. It has the most owner ratings in this group.

Best for Two Cats: ONBRILL 59-Inch Cat Litter Box Enclosure has two rooms, each 22 by 18.5 by 18.9 inches inside, magnetic double doors, and four vent holes in the back. At a listed 59 inches long and 67 pounds, it needs a long wall.

Best Ottoman-Style Pick: Zerbuger Cat Litter Box Enclosure Furniture is a polyester ottoman with a flip-up lid and a removable divider, listed at 30 by 20 by 20 inches and rated by the maker to hold 200 pounds on top.

Frequently Asked Questions

What size litter box fits in a large litter box enclosure?

Check the listed interior size, not the outer size. Most double cabinets here fit boxes about 19 to 22 inches long per room; for a box around 24 inches, look at the Amunrbrek or Zerbuger.

Is a double litter box enclosure good for two cats?

It saves space, since two boxes share one footprint. Some cats will not share a cabinet, so watch for accidents outside the box and keep another box in a different room.

Will an enclosure hide litter box smell?

It hides the box, not the smell. Scoop daily and choose a cabinet with vents. For boxes built around odor control, see our odor control litter box picks.

How do I clean a wooden litter box enclosure?

Pull the box out, wipe the floor and walls with a damp cloth, and dry the surface right away. A washable liner or mat under the box protects engineered wood from spills.

How do I get my cat to use a new enclosure?

Put the cat’s current box inside with the doors open, in the same spot if you can. Add familiar litter, and keep a second box nearby until your cat uses the enclosure consistently.
