Crystal tray~$230PetSafe
Take the Crystal Plus, add a removable hood and a digital counter that logs how often the box is used, and this is the result for about $30 more. The hood stands the unit 16 inches tall and gives the cat some privacy; running costs are unchanged at roughly one $23 tray a month for a single cat.

Best for: Cats that want a covered box, with an owner who likes a visit log without an app
PetSafe 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: sensor type not published. The maker does not state any anti-pinch protection.
How minimum weights work, and what to do below themNo drawer: the disposable tray is the unit you replace. The maker rates a tray for up to 30 days with 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.
