How often do I change the tray?

PetSafe says one tray lasts weeks for a single cat. Multi-cat homes need more frequent changes, and odor usually signals it is time.

Does it work with clumping litter?

No. It is designed for the crystal litter sold in the ScoopFree trays. Clumping clay can jam the rake.

Is it safe for kittens or small cats?

The safety sensors stop the rake when a cat is inside, but the box is sized for adult cats. Very small kittens may struggle with the entry.

How much do replacement trays cost?

Trays are sold in multi-packs and cost more per change than bagged clay litter. Factor that into the $99 box price.

It is the lowest new price among 8 stores as of November 5, 2026, so it is a strong time to buy if you accept the tray costs.

Does the app do anything useful?

The Wi-Fi app can alert you to cycles and issues, but the box runs on its own. Most owners do not need it.
