Buying Guide for Extra Large Litter Boxes

Size and Capacity

When you have four cats, the litter box must be generous enough for each cat to turn, dig, and squat without feeling cramped. Look for dimensions that are at least 1.5 times the length of your largest cat. The Tevila XL Enclosed model offers 23.6 inches by 15.7 inches, while the open top version is 22.8 inches by 14.5 inches. Both provide deep basins that hold more litter, reducing refill frequency. For cats of varying sizes, our guide on best litter boxes for three cats with different sizes offers additional insights.

Material and Odor Control

Stainless steel is a superior choice for multi-cat homes because it is non-porous, scratch-resistant, and does not absorb odors like plastic. The Tevila models feature stainless steel trays that prevent lingering smells and are easy to rinse. The Arm & Hammer sifting box uses Microban protection to inhibit odors, though its plastic construction may require more frequent cleaning. For a deeper dive into odor management, explore the multi-cat litter boxes category.

Ease of Cleaning

With four cats, you need a box that simplifies daily scooping or sifting. The Arm & Hammer sifting litter box uses a lift-to-sift mechanism that separates clumps from clean litter without scooping. The Tevila open top model has smooth rounded corners that make rinsing quick, and its non-stick surface prevents residue buildup. The enclosed version includes a step board and litter mat to reduce tracking, saving you cleanup time.

Additional Features

Consider extras like dog-proof latches, carbon filters, and anti-slip pads. The Tevila XL Enclosed has a lockable latch to keep curious dogs out, plus a carbon filter for strong odor control. The open top model comes with non-slip pads and a scoop. If you value smart features, see our picks for best smart litter boxes for pet sitters.
