Find an automatic litter box for your home

Start with your cats and the space available. Add exact measurements or connected features only when they are essential; a missing specification is not treated as a match.

Manufacturer capacity and weight ranges are comparison guides. Check the opening, interior room and safe automatic-mode age and weight limits against your cat. App and bundle requirements are exact-package filters, not a guarantee that any offer contains an accessory.

Your cats and the box

Use the maker’s stated fit range as a first filter; then consider your cat’s posture, entry needs and litter tolerance.

Choose the litter format your cat must keep. Crystal-tray rakes such as PETKIT Crystal Duo and PetSafe ScoopFree use model-specific trays; do not assume supplies interchange. Clumping litter, water-soluble CatGenie litter and reusable CatGenie granules are different operating plans. Unknown litter compatibility does not match. A specific bentonite, mineral, tofu, or mixed-litter answer requires exact manufacturer compatibility; tofu/mixed compatibility does not mean the matching sieve is included.

Add exact measurements and limits (optional)

This checks the published household capacity; it does not promise a particular emptying interval.

Leave blank if this is not essential. Whisker says its reviewed models need a cat of at least 3 lb for automatic mode; under that weight, follow its supervised semi-automatic instructions. Casa Leo’s LLT manual also prohibits Automatic mode at or below 3 lb but does not state a dependable higher minimum; if weight is essential, an unknown threshold does not pass. Manufacturer limits can use tenths of a pound, so the 4.4 lb AutoEgg boundary is represented exactly. The entry accepts hundredths of a pound where a maker publishes that precision; do not round an exact threshold down.

Leave blank unless age is a hard requirement. This uses an explicit manufacturer minimum age; it does not replace a separate minimum-weight rule.

Optional. Cumrige M6’s linked quick guide recommends at least 15 cm at the shoulder. Other models have no recorded threshold here; unknown does not satisfy an essential fit requirement.

Leave blank if weight is not a deciding requirement. Also compare the entrance and interior dimensions with your cat. This field uses tenths of a pound to preserve published manufacturer thresholds such as 15.4 lb.
