ELS PET
The 2026 open-top Orbitie is built for big cats, with a 33 lb rating and a 16.1-inch-wide opening. ELS PET is less precise elsewhere: the page gives the kitten threshold as 2.2 lb in its FAQ, 2.3 lb in its weight range and 2.5 lb in its Kitten Mode description, so the site uses the highest. No drawer volume is published.

Best for: Large-breed households that want an open box
ELS PET says the sensor detects cats from 2.5 lb. At the usual rate of about a pound a month, that means leaving automatic cleaning off until roughly 3 months. Below the threshold, a kitten may not register at all, and the box could start a cycle with it inside.
Detection: sensor type not published. The maker does not state any anti-pinch protection.
How minimum weights work, and what to do below themThe maker publishes no drawer volume, so the days cannot be worked out.
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 ELS PET Orbitie Air yet. This section stays empty until there is something real to put in it.
