The Dome exists because most enclosed litter boxes are designed around an average-sized cat, and larger cats end up cramped, reluctant, or hanging half out of the entrance. Here's what's actually different about it.
The Real Numbers
The Dome measures 46 × 46 × 64cm overall, with approximately 30% more interior space than standard enclosed litter box designs — suited to cats up to 6.8kg (15lbs). That extra interior volume is the actual point: more room to turn, dig, and posture comfortably without the enclosure itself feeling restrictive.
Why Enclosed, Not Open
An enclosed design contains odour more effectively and gives cats the privacy many genuinely prefer — but a small enclosed box can feel more restrictive than an open tray of the same footprint, since a cat can't step outside the boundary to dig or turn as they might in an open tray. The Dome's extra interior space is specifically there to offset that trade-off for larger cats.
Practical Design Details
- Front-entry opening with a transparent door panel, so you can monitor use without disturbing your cat or losing the enclosed design's odour control
- Smooth, wipe-clean interior and exterior surfaces for straightforward cleaning between full changes
- A compact 46 × 46cm footprint despite the larger interior volume — designed to fit bathrooms or utility spaces without needing an oversized room
Is It Right for Your Cat?
If your cat is at or near the 6.8kg upper limit, it's worth checking your own cat's measurements against the tray's internal dimensions rather than assuming "large cat litter box" alone guarantees a comfortable fit — the same principle covered in How Do I Know If My Cat's Litter Tray Is Too Small?. For cats meaningfully over that limit, an open large-breed tray may suit better than any enclosed design, regardless of brand.
