IRIS USA Large Cat Litter Box with Scatter Shield and Scoop (Open Top, High-Sided) vs IRIS USA Top Entry Cat Litter Box with Scoop
Which should you buy? Our verdict on both, pulled from our full The Best Cat Litter Boxes: 4 Compared (and One to Skip) comparison.
The high-sided open pan is the safest choice for the widest range of cats: it contains digging, welcomes any cat in, and stays easy to clean. If tracking is your real enemy and your cat is a nimble adult, the top-entry cube is the better tool.

IRIS USA Large Cat Litter Box with Scatter Shield and Scoop (Open Top, High-Sided)
Buy itA big, tall-walled open pan that stops scatter without ever confusing a cat about how to get in.
- Tall clear scatter shield rings three sides so litter kicked during digging drops back into the pan instead of onto the floor
- Wide, open interior with a low front entry that cats of any age or size accept without hesitation
- Nothing to trap odor: the fully open top means no hidden funk and no filter to buy
- Comes with a matching scoop that clips to the side, and the smooth plastic wipes and rinses clean quickly
- Open design does nothing to hide the box or contain smell between scoops, so placement matters
- The tall shield is great for diggers but adds visual bulk in a small bathroom

IRIS USA Top Entry Cat Litter Box with Scoop
Buy itThe tracking fix: a top-entry cube that keeps litter in and curious dogs out.
- Cat enters through a hole in the grated lid, and the perforated top acts as a walk-off mat that shakes litter back inside
- Best-in-class scatter control among the boxes here, which is the whole reason to buy one
- High walls and a covered top deter dogs and toddlers and largely contain odor and stray spray
- Simple two-piece design lifts apart for cleaning and comes with a hanging scoop, at a budget price
- Cats must climb up and drop in, which rules it out for kittens, seniors, and cats with mobility issues
- The interior is smaller than an open pan, so very large cats have less room to position and turn
