IRIS USA Top Entry Cat Litter Box Review: Less Tracking, Less Peeking

This box has racked up tens of thousands of ratings for a simple reason: top-entry design genuinely cuts down on tracked litter in a way front-entry boxes often can’t. Because the only way in or out is through the grooved lid opening, most of the litter clinging to a cat’s paws gets knocked loose before they hop down, rather than getting carried out through a doorway at floor level.

It’s also fully enclosed on all sides, which owners consistently point to as a second big selling point. For multi-pet households, a sealed box with a single top opening is much harder for a dog to nose into or knock over than an open pan or a front-door covered box. The scoop that’s included out of the box is a nice touch too — no separate purchase needed to get started, and it’s sized to fit the box’s footprint.

Setup is straightforward: snap the base and lid together, drop in litter, and it’s ready. The enclosed design does a good job containing odor between scoopings, which matters if the box lives in a small bathroom or laundry room rather than a garage. Being made in the USA is also something reviewers frequently mention as reassurance around build quality and part fit.

Where it takes some adjustment is cleaning. Because you’re working through a top opening instead of lifting off a whole lid or sliding out a front panel, scooping means reaching down into the box rather than sweeping across an open pan, and some owners find the corners and lid grooves a bit fiddlier to keep spotless. It’s a trade-off: the same enclosed shape that blocks tracking and keeps dogs out also makes a full wipe-down slightly more of a chore than an open box.

The most common complaint is that the tabs holding the lid to the base can fit loosely, so the lid may shift or need occasional re-seating rather than locking down with a firm, permanent snap. It’s rarely reported as a dealbreaker, more of a "wish it were snugger" note. The bigger consideration is the entry method itself: climbing up and into a top opening isn’t a great fit for larger cats, senior cats, or any cat with joint pain or mobility issues, since it asks for a bit of a jump and a squeeze rather than a simple walk-in. If that describes your cat, a low-entry or front-door box is a better match regardless of how well this one controls tracking.

If your main headache is litter scattered across the bathroom floor, or you’ve got a dog that treats the litter box like a snack bar, this is one of the more proven, budget-friendly fixes on Amazon — the volume of repeat purchases and long track record back that up. It’s an especially good match for single-cat or multi-cat households where every cat is young, healthy, and agile enough to hop up and in without hesitation.

Skip it if you have a senior cat, a larger breed that might feel cramped, or a cat that’s already shown reluctance around covered boxes — privacy-loving cats sometimes take to it fine, but a cat that dislikes enclosed spaces may avoid it altogether. When in doubt, keep an open box available alongside it during the transition so your cat always has an option they’re comfortable using.
