Automatic Litter Boxes by Published Noise Rating

A cycle that runs at 3 a.m. in a small apartment matters, and a skittish cat that hears the drum turn may stop using the box. Only 20 of the boxes in this catalog publish a decibel figure at all, and none says how far away the microphone was, so a 35 against a 40 settles nothing. What the list does show is who is willing to put a number on it; Whisker, the best-known name in the category, publishes none.

How this list is ordered: Every box with a published noise rating, ordered from the lowest figure. No maker states its measuring distance, so small gaps mean little. 20 of the catalog’s boxes qualify. 1 of them carries a maker safety notice, not a recall — Neakasa M1 Plus — shown on the card and the model’s page.

1Casa Leo

homerunPET CS106 Self-Cleaning Litter Box
The CS106 is named for its 106-litre dome, which homerunPET bills as the largest on sale, and it refills its own litter: a 4.5-litre reservoir feeds the 8-litre bed when a sensor reads it low.

~$219
CATLINK Scooper SE Lite
About $40 less than the SE buys the same 70-litre globe, 7-litre drawer and sensor set: CATLINK lists infrared, weight and anti-pinch sensors for both, and what the Lite gives up is not spelled out beyond the SE's multi-cat billing and its pink colour option.

Neakasa M9 Open-View Litter Box
