Frequently Asked Questions

Absolutely. The spacious 75L inner basin gives adult cats weighing up to 16.5 lb (7.5 kg) plenty of room to turn around comfortably – and it’s roomy enough for multi-cat households, too.

Yes. The donut-shaped design features a built-in litter-grooming pedal along the inner edge that catches scattered litter as your cat steps out of the entrance. And if you have cats with normal jumping ability, you can install the included one-way door – your cat enters through the door and hops out through the top opening after doing their business, which dramatically cuts down litter tracking.

Not at all. The top lid comes off in seconds – just lift it open to dump used litter. The inner basin is completely seam-free with no hard-to-reach grooves, so a quick rinse under water is all it takes to keep it spotless.

Yes. The circular entrance sits just 5.9 in (15 cm) off the ground, making it smooth and easy for kittens, senior cats, and short-legged breeds to enter and exit with confidence.

Unlikely. The door opens with very light resistance – your cat just needs a gentle nudge with their head to push through. It’s also fully removable: take it off anytime to turn the box into a semi-open litter box. For kittens or first-time users, we recommend leaving the door off during the adjustment period and reattaching it once your cat is comfortable using the litter box.

The box includes a magnetic one-way door and a 2-piece scoop set (daily scoop + litter-change scoop).

We recommend a litter depth of about 1.8 in (4.5 cm). To reach that ideal depth, you’ll need 3 bags of tofu litter (5.3 lb / 2.4 kg each), 3 bags of cassava litter (5.3 lb / 2.4 kg each), or 2 bags of mineral litter (9.9 lb / 4.5 kg each).
