5 ways to get the waste out of the box

Rotating drum

26 models · from $219

An enclosed globe turns and sifts clumps through a screen into a drawer. The most common design, and the one with the most published safety data.

Open-top

12 models · from $149

No hood or globe over the cat; the bowl tilts or rotates beneath an open rim. Suits big cats and cats that avoid enclosures.

Crystal tray

6 models · from $100

A rake sweeps a disposable crystal tray that you throw away every few weeks. Cheap to buy, recurring to run.

Rake

3 models · from $219

A comb travels across a fixed litter bed and pushes clumps into a bin. Low and pan-like, with more litter exposed.

Flushing

2 models · from $469

Plumbed to a water line and a drain; washes itself and sends waste down the pipe. Nothing to empty, a lot to install.

Every box in the catalog

Filter by maker, mechanism, litter and price. The default order puts the boxes that detect the lightest cats first, because that is the figure that decides whether a box is safe to automate around a young or small cat. Tick up to three to line their specifications up in one table.

Lists built from the catalog, each saying what it ranks on

Self-Cleaning Litter Boxes Rated for Large Breeds

13 qualifying boxes

Every box rated by its maker for cats of 25 lb or more, ordered by that rating and then by price.
