What You Are Buying

The IRIS USA Premium Top Entry Litter Box is a large-capacity manual litter box with a square footprint and privacy walls around the top-entry opening.

Cats climb in and out through the lid, which doubles as a litter-catching walk-off mat.

It ships with a matching scoop.

There's no built-in liner or filter system, so owners use their own litter and any disposable liners they prefer.

Performance

Tracking control: The top-entry lid genuinely reduces the amount of litter tracked onto surrounding floors, since a cat's paws pass through the lid opening on the way out, knocking loose litter free before it leaves the box area.

Odor control: The privacy walls help contain digging spray and odor inside the box rather than letting it escape into the surrounding room, a meaningful upgrade over a fully open pan.

Capacity: The large square size comfortably fits bigger cats and stands up to shared use by two cats, though the one-box-per-cat rule still applies for genuinely multi-cat homes.

What It Does Well

It's a budget-tier product that also earns strong, consistent review volume in its category.

The large square footprint gives bigger cats real room to turn around and dig, something many smaller top-entry boxes skimp on.

What Falls Short

This is a fully manual box, daily scooping is required regardless of the tracking or odor advantages built into the design.

Top-entry mode isn't universal.

Kittens, senior cats, and cats with mobility limitations generally do better with a low front-entry box, and choosing top-entry for the wrong cat can lead to litter box avoidance.

There's no app, no health tracking, and no automatic cycle, a genuine tradeoff for owners who want that layer of monitoring.

Who Should Buy It

The IRIS USA Premium Top Entry Litter Box is right if: you want a well-reviewed manual box, have a larger cat or multi-cat household, and are comfortable with daily scooping in exchange for a much lower price than automatic boxes.

Consider alternatives if: you want automated cleaning (ScoopFree Ultra or CATLINK Luxury Self-Cleaning Litter Box), have a senior or mobility-limited cat (use a low front-entry box instead), or want app-based health tracking.

Answers

Frequently asked questions

Is the IRIS USA Premium Top Entry Litter Box big enough for a large cat?

Yes, it's built as a large square design with more interior floor space than a standard top-entry box. Large cats have enough room to turn around and dig comfortably, which is the main reason to choose this size over a smaller top-entry model.

Is top-entry a good design for every cat?

Top-entry mode traps more litter on exit since the cat has to climb up and through the lid, which acts as a walk-off mat. It isn't ideal for kittens, senior cats, or cats with mobility limitations, since it requires climbing up and over the rim rather than walking in through a side opening.

Does the IRIS USA Premium Top Entry Litter Box come with a scoop?

Yes, a matching scoop ships with the box. It has no built-in liner or filter system, so owners use their own litter and standard disposable liners if desired.

Does the IRIS USA Premium Top Entry Litter Box reduce litter tracking?

The top-entry, litter-catching lid traps litter from a cat's paws as they exit, and the privacy walls help contain any digging spray inside the box. It won't eliminate tracking entirely, but it's a noticeable improvement over an open pan.
