Extra Large High Sided Litter Box for Big Cats

This high-sided litter box stands 13.8 inches tall, designed to prevent litter scatter and urine splashes. It measures 22.6″ by 14.8″ by 13.8″ to provide ample space for big cats or multi-cat households. The open top encourages airflow and easy monitoring of cleanliness and odor levels. Best for active diggers who need a tall barrier to keep mess contained, and for households prioritizing quick, straightforward cleaning. A limitation is that the open top may be less effective at containing stronger odors in very small rooms.
Stainless Steel Litter Box With Lid for Big Cats

This XXL metal litter box uses a high-sided design with a lid and a long-side entry for easy turning. The 0.8mm thick stainless steel is scratch-resistant, rust-proof, and non-stick, simplifying cleaning and reducing odor retention. It includes a double-extended overlapping seal to minimize urine leakage, making it best for cats who stand to urinate or have higher urine output. Choose this if you want durability and a premium material that resists staining; avoid if you need a lighter, plastic option for portability.
IRIS XX-Large High Sided Litter Box

Designed for multi-cat households or larger breeds, this IRIS XX-Large model features generous dimensions (30″L x 20″W x 14″H) and a scatter shield to reduce mess. Its smooth interior simplifies cleaning and minimizes crevices where litter can accumulate. Best for multi-cat homes needing substantial space and easier maintenance, with a note that larger units require more space in the room.
