From documented evidence only

Who this appears to fit

Good fit if…

You use clumping clay litter — the manufacturer's manual states this is supported
Your heaviest cat is under 33 lb — the stated maximum according to the manufacturer
Your cat avoids enclosed boxes — this is an open-top design
You want to try it before committing — the manufacturer documents a 45-day trial

Not a documented fit if…

You use tofu, crystal, pine pellet and other pellet litter — the manufacturer excludes or advises against it
Your cat is over 33 lb — the manufacturer states that as the maximum

Each line above is derived from a value the manufacturer published; the source is shown against that value in the evidence table below. PURRINDEX draws no conclusion from a field a manufacturer left blank.

Original PURRINDEX drawings

Dimensions & footprint

Drawn to scale by PURRINDEX from the published dimensions below. An original drawing, not a product likeness and not manufacturer artwork.

Factual list, not a score

Documented mechanisms

weight sensor (cat presence)
cat-entry detection at a weight change greater than 3 lb (1.5 kg)
cleaning cycle starts only after the cat leaves

These are the mechanisms the manufacturer documents. PURRINDEX does not rank or score safety, and the number of listed mechanisms is not a measure of anything. Manual

Known unknowns

What the manufacturer does not state

The manufacturer does not publish an entry height
The manufacturer does not publish interior dimensions

Absence of documentation is not evidence of a shortcoming in the product. It is a statement about what you can and cannot find out before buying.

Chosen by documented similarity — price band, form factor and the litter types each manufacturer states. Never by what a merchant pays.
