Shortlist

Automatic litter boxes that support tofu litter

You already use tofu litter and do not want to switch. This list contains only products whose manufacturer explicitly states tofu is supported.

What qualifies a product for this list

The manufacturer's own documentation states tofu litter is supported. Products where the manufacturer is silent are excluded — silence is not permission, and PURRINDEX does not infer compatibility from an opening size or a mechanism type.

5 of 44 indexed products qualify. Evidence captured 2026-09-01 from the sources named against each value.

Limits of this list

What is still unknown

Products absent from this list are not necessarily incompatible with tofu litter. Most are absent because their manufacturer publishes no litter guidance at all. Absence here means undocumented, not unsuitable.
