Which is better for a multi-cat home?

The Litter-Robot 4. It is rated for up to 4 cats and a 3-25 lb weight range, while PetSnowy does not state a multi-cat capacity.

Is the Litter-Robot 4 worth the extra $170?

For multi-cat homes or large cats, yes. For a single small cat, the SNOW+ covers the basics for less and adds a litter walkway.

Which controls odors better?

Both seal waste and filter air. PetSnowy claims a 90.5% ammonia removal rate with TiO2, but owners report a strong chemical scent from its auto-deodorizer. The Litter-Robot uses a sealed carbon-filtered drawer.

Which is easier to clean?

The Litter-Robot 4 has a sealed drawer you empty every few days. The SNOW+ uses auto-sealing bag packs, but owners say litter smears inside the globe and needs deep cleaning.

Do both work for kittens?

PetSnowy requires cats at least 6 months old and 3.3 lbs. The Litter-Robot 4 lists a 3 lb minimum, so check your kitten's weight against each limit.

Which takes up less space?

The SNOW+ at 0.38 m² (4.1 ft²). The Litter-Robot 4 measures 22'' x 27'', roughly 4.1 ft² as well, so the difference is small.
