Meowant Self-Cleaning Cat Litter Box, 106L Large Capacity for Multiple Cats

Why it's worth it

The MeoWant SC09 Plus is the box to get if your cat is big, old, or both. A 106-liter interior and an 8.27-inch entrance mean no climbing and no cramped turns, and the gearing keeps the opening facing outward through the whole cycle.

Most self-cleaning boxes are built around a globe with a high, round mouth, and plenty of cats simply won't climb into one. The MeoWant's opening sits a little over eight inches off the floor. For an arthritic fourteen-year-old, a heavy cat, or a short-legged breed, that's the difference between using the box and leaving you a surprise on the bath mat. Owners with big cats often say adoption was immediate.

The interior is the other half of the pitch. At 106 liters it's the roomiest box here, rated for cats from about three to thirty pounds, and a Maine Coon can turn around without brushing the walls. That space costs you floor, though: this is a wide, low appliance rather than a tall one, so measure the corner you have in mind before you order.
