PetSafe has a solid track record for automated pet care, but the OpenSky stands out for its open-top design. Most self-cleaning boxes are enclosed caves that cats can be wary of. This one removes that barrier entirely. The result is a litter box that feels more like a standard pan, which makes the transition easier for picky cats while still handling the dirty work for you.

The cleaning mechanism is straightforward. After your cat leaves, a rake cycles through the crystal litter and pushes waste into a sealed 8.5-liter drawer. For a single cat, that drawer genuinely lasts two weeks before you need to touch it. The crystal litter absorbs moisture and controls odors better than clay, so the box doesn’t smell between changes. The open top also means larger cats won’t feel cramped, and you can see inside at a glance to know when it needs emptying.

There is one trade-off worth noting. Because the top is open, odors escape more freely than with a fully enclosed unit. The crystal litter handles this well, but you’ll want to place it in a ventilated area. The footprint is also substantial at 20 inches wide and 24 inches tall, so measure your space first. For a low-stress, hands-off cleaning routine that doesn’t trap your cat in a box, this is a practical solution.
