IRIS USA High Sided Cat Litter Box with Scatter Shield Review (2027)
Research review of the IRIS USA High Sided Litter Box with Scatter Shield (CLH-12): open-top access, tall walls, and scatter control for two-cat homes.
IRIS USA High Sided Cat Litter Box with Scatter Shield
Open-top acceptance with high walls and a snap-on shield for diggers and sprayers.
Our verdict
The shield version of IRIS's high-sided box splits the difference between open and enclosed: cats get the open entry they accept, and owners get walls that actually contain the dig. For two-cat homes with a sprayer or a kicker, it is the practical middle path.
What we like
- High walls plus a removable scatter shield contain kicked litter and spray
- Open-top format is the design most cats accept immediately, with easy entry
- Roomy large footprint gives two cats space to turn and dig
- Smooth plastic surfaces wipe and wash clean without liners snagging
What to watch out for
- Open top does not contain odor like enclosed boxes
- The shield is one more piece to remove and wash
- Determined kickers can still clear the lowered front entry
What owners report: IRIS USA High Sided Cat Litter Box with Scatter Shield
Synthesized from recurring themes in long-term owner feedback.
Most praised
- Tall walls plus the snap on shield contain most kicking and spraying without enclosing the cat
- Cats step in easily over the low front, so acceptance is rarely an issue
- Smooth surfaces wash clean without a liner catching on the scoop
Common complaints
- An open top cannot hold odour in the way a hooded box can
- The shield is an extra piece to lift off and wash at deep clean time
- Enthusiastic diggers can still send litter over the lowered front
Who it is for
Two-cat households and owners of high sprayers or enthusiastic diggers who want open-top acceptance with containment.
Walls where the mess happens
Litter leaves a box at the back and sides, where digging and spraying aim. This design raises those walls and adds a snap-on scatter shield on top, while the front stays low for easy entry.
That geometry suits older cats and kittens too, who struggle with tall entries on fully enclosed boxes.
Open top, honestly assessed
Open boxes are the format most cats use without hesitation, and scooping is a reach-in job with no lid to park. The trade is odor: nothing seals, so litter choice and scooping frequency do the odor work.
In a two-cat rotation of boxes, an open shielded box like this is often the one cats choose first.
Size and cleaning
The large footprint gives two cats genuine turning room, which matters for shared boxes where a cramped cat starts missing. Smooth plastic washes clean without the texture that traps residue.
The shield removes for washing, one extra piece in exchange for the containment it provides.

Questions, answered
Is this box big enough for two cats to share?
It is a large open box with room to turn and dig, sized for shared use in the two-cat rotation most homes run.
Does the shield make it an enclosed box?
No. The shield raises the walls against scatter and spray, but the top stays open, so odor control still depends on litter and scooping.
