SC02 is a candidate only when your cat comfortably clears its 6.1-inch entrance, accepts an enclosure and fits the 3.3 to 22 lb range. A lower step is not proof of easy access. If climbing or turning is difficult, prioritize an accessible familiar tray and veterinary advice. PetSafe Crystal Pro is a different open rake design, but its 6.2-inch overall height is not a verified entrance-step measurement.

What matters in practice
Age alone does not settle the choice. Comfortable movement and acceptance do.
SC02 lists a 6.1-inch entrance. PetSafe’s 6.2-inch body height describes a different measurement, so subtracting the two would create a false access comparison. Check the actual threshold and room to turn.
A cat may clear the step but struggle to turn inside, or reject a covered box it could physically enter. Observe both parts of the movement. For entry or exit difficulty, a familiar accessible conventional tray is a more appropriate starting point than an automatic-box upgrade.
2 options

Meowant, MW-SC02
A shallower enclosed box with a 6.1-inch entry for cats within its 3.3 to 22 lb range. The 75 L headline includes more than the 51.7 L toileting space. Allow room to clean and change waste bags regularly.

Cat age must exceed 4 months and weight must fit the 3.3 to 22 lb range. Entry and turning still need to be comfortable.
