11 Best Litter Box for Large Cats of 2026: Tall Sides That Actually Stay On

The Van Ness Pureness delivers a 21-inch length and 9.25-inch sides at a budget-friendly price, making it one of the roomiest open pans for large cats. The polypropylene construction resists stains and cleans easily, holding up well in multi-cat households. For cats with normal litter habits, the high sides contain most scatter. However, the sides are only 9.25 inches tall, so cats that spray upward or kick aggressively will overshoot — this pan works best when you accept those boundaries.

The Yangbaga is crafted from a single piece of stainless steel with 12-inch sides and a U-shaped cutout. Unlike enclosed designs, this open pan removes the risk of lid failures and provides maximum side height for cats that spray high.

For owners of large, high-spraying cats who prefer an open box, the Yangbaga offers exceptional durability and odor control. However, the bare steel surface can cause litter to stick more than coated pans, and the cost may give budget-conscious buyers pause.

The triangular shape fits neatly into corners, providing an unusually large interior (26x23x20 inches) that accommodates large breeds and multiple cats comfortably. The lid does not latch — it can detach when the box is moved or if a heavy cat jumps against it. Access is generous through the front door and open top, making scooping and scrubbing simple. For owners who plan to keep the box stationary in a corner and want maximum interior volume at a mid-range price, this is a practical option.

This box offers a generous 25-inch interior and a flip-up front that makes scooping easy, but the 11.75-inch sides may not contain high-peeing cats and the plastic latches on the front flap can break with use.

The stainless steel pan resists odors and cleans easily, and the included mat and scoop add value. But the 11-inch side height is lower than competitors, so cats that spray high may overshoot, and the plastic lid can feel wobbly. This suits cats up to 15 lbs that don't spray high.

Spacious enough for large cats, the 24-inch interior and carbon filter control odors at a mid-range price, and cleaning is simple. However, the lid can detach during moves or cat use, making it best for stationary placement where lid security is not a priority.

The IRIS USA top-entry box keeps litter contained effectively and has an easy-to-clean, attractive shell. However, the interior is snug for cats over 15 lbs, and the lid can collapse under a heavier cat's weight. This makes it a good fit for smaller, heavy-digging cats rather than the large-cat buyer searching for extra space.

The Petphabet Jumbo Hooded offers a generous 24.8-inch interior and a clear top that makes spotting messes simple. The spacious design and effective litter containment suit multi-cat households, but the plastic can crack at the opening or lid under regular use, and the lid clips may not hold securely over time. This box works best for owners who handle it gently and prioritize visibility over long-term toughness.

The stainless steel pan resists odors and wipes clean easily, and the XL size with 12-inch sides fits large cats up to 18 pounds. However, the metal can scratch from routine scooping and the plastic lid’s fit may vary between units, making the similarly priced WoofiGo a more polished choice for owners who want a cleaner look and a more secure seal.

At 29 inches long with 15-inch sides, this is the largest litter box system available — purpose-built for extra-large cats and high sprayers. The zeolite pellets and disposable pads capture urine without dust or tracking, which is a major advantage for owners with allergies. However, the proprietary refills add recurring costs, and odor control depends on changing pads on a fixed schedule; missed changes may produce ammonia smells. This setup suits multi-cat households and those who prioritize zero dust and less daily scooping over long-term expense.
