Large Pet Carrier With Litter Tray (Design J)

I selected  Litter Box precisely because it allows me to give my cats different options to best meet their toileting needs. The first option with this box is to use the base alone without adding the cover. With high, rounded sides, the 25.25-by-18.75-inch pan is spacious and sturdy.

The second option is to add the cover. It snaps into the base in four places and has a handle and a charcoal filter for absorbing odors. Unlike some covered litter boxes, there is no plastic door a cat will need to push through that may also swing disconcertingly once the cat is inside the box.

The third option is to flip the front of the cover up so it opens up about a third of the box. This makes for easy cleaning and, if left in this position, also creates a hybrid covered-uncovered box that may better meet the requirements of both cat (easy entry and no over-confinement) and guardian (odor control and less visible waste).
