SC02 comes into consideration only if your cat gets over its 6.1-inch entrance comfortably, accepts an enclosure and falls within the 3.3 to 22 lb range. A lower step does not prove access is easy. If climbing or turning is hard for your cat, put an accessible familiar tray and veterinary advice first. PetSafe Crystal Pro is a different design, an open rake, but its 6.2-inch overall height is not a verified entrance-step measurement.

Decision guide
A cat's age does not decide this on its own. Comfortable movement and acceptance do.
A 6.1-inch entrance is what SC02 lists. PetSafe’s 6.2-inch body height is a different measurement, so subtracting one from the other would give a false comparison of access. Check the actual threshold and room to turn.
A cat might get over the step and then struggle to turn around inside, or it might refuse a covered box it is physically able to enter. Watch both parts of the movement. When entering or leaving is difficult, a familiar, accessible conventional tray is a better place to start than an automatic-box upgrade.
2 options

Meowant, MW-SC02
This enclosed box is shallower and has a 6.1-inch entry, for cats in its 3.3 to 22 lb range. Its 75 L headline figure covers more than the 51.7 L toileting space. Leave yourself room to clean it and swap waste bags on a regular basis.

Your cat has to be older than 4 months and weigh within the 3.3 to 22 lb range. Getting in and turning around must also be comfortable.

PetSafe, Crystal Pro Legacy
Crystal is the documented litter fit, and the cabinet is 19.1 inches wide.
Pick this instead ifThe open rake layout is a different design, so consider it only once you have checked the exact entrance, the supported litter and how your cat really moves. Overall body height alone cannot show that access is easier.
You depend on proprietary crystal trays.
