Stainless Steel Litter Box with Lid, 135 Flip-Top XL Extra Large

In this review the Stainless Steel Litter Box with Lid, 135 Flip-Top XL is assessed for multi-cat homes and owners who want low-maintenance odor control. The bottom line: this is a durable, high-capacity enclosed litter solution built around a deep 8in stainless steel base that holds up to 40L of litter, so it reduces change frequency and largely prevents urine spray. The review focuses on cleaning ease, build quality, and whether the dual-entry design and included accessories make it a practical daily option.

Key Features

• 100L Extra-Large Capacity: The outer shell measures 23.6in by 15.7in by 17.3in and the 8in deep stainless steel base stores up to 40L of litter to run 30-35 days for many adult cats.
• Top-Flip Cleaning Convenience: The flip-top cover lets owners clean without fully removing the lid, avoiding awkward corners and making routine scooping quicker.
• Complete Litter Set: The package includes two scoops, a litter mat and a filtration stepping board so the system traps more scattered litter and reduces tracking.
• Dual Entry Options: Side and top access let cats choose how to enter, while the 17.3in height and 8in base help reduce spray and prevent litter from spilling out.
• Premium Odor-Controlled Durability: Industrial-grade PP and stainless steel construction with activated carbon filtration resists warping and controls odors over long-term use.
• 3-in-1 Configurations: Snap-together assembly offers fully enclosed, semi-open, or open setups and features rounded CNC corners for easy cleaning and no sharp edges.

Who It's For

The Stainless Steel Litter Box with Lid, 135 Flip-Top XL is ideal for multi-cat households, owners of larger breeds, or anyone wanting a low-odor, low-maintenance enclosed box that needs fewer litter changes. It suits households that value a durable metal base and the option to switch between enclosed and open configurations.

Owners who need a travel-sized or very compact tray should look elsewhere, since this model is extra large and intended for permanent placement. Very timid cats that refuse enclosed spaces may also prefer a fully open pan instead of any enclosed option.

Pros & Cons

Pros

• Includes two scoops, a filtration stepping board, and a litter mat to cut tracking and keep odor down.
• Durable combination of PP and stainless steel resists warping and is easy to sanitize.

Cons

• The XL size and 17.3in height make it bulky for small bathrooms or travel; it is best as a stationary home litter solution.
