Meowant
Barely 7.8 inches tall, this looks like an ordinary litter pan until the two rakes move. Three motors travel, rotate and lift the waste into a sealed compartment, and four corner weight sensors stop the cycle when a cat approaches. Its maker is candid about the small compartment: empty it daily in summer and every two to three days otherwise, even with one cat.

Best for: Cats that will only use something that looks like a normal pan
Price and stock there may differ from the figure above.
Meowant publishes neither the lightest cat this box detects nor a minimum age. Until it does, treat it as unsuitable for automatic cleaning around a kitten and run it by hand.
Detection: weight. The maker states anti-pinch protection on the moving part, by sensor or by design.
How minimum weights work, and what to do below themThe maker publishes no drawer volume, so the days cannot be worked out. Its own claim is up to 3 days for one cat.
The two lists above are drawn from the maker’s own pages, manuals and prices, not from owner reports. Where owner discussion has been read it appears in its own section below, so the two are never mistaken for each other.
No owner discussion has been read for the Meowant MW-SC03 yet. This section stays empty until there is something real to put in it.
