How do I introduce my cat to a hidden litter tray?

Introduce a hidden litter box gradually while keeping a familiar accessible tray available. First make sure the cabinet and tray combination offers sufficient usable space and an uncomplicated entrance. Let the cat investigate the empty furniture without being placed inside or having the exit closed. Then introduce the familiar tray and litter arrangement where practical, avoiding several changes at once. If the cabinet design allows its doors to remain safely open, that can make the space less enclosed initially.

Watch normal use rather than repeatedly carrying the cat to the entrance. Do not remove every alternative simply to force acceptance. If the cat avoids the setup, check the entrance, internal space, location and cleaning access before persisting. Sudden toileting difficulties also merit veterinary advice. Successful introduction means the cat chooses to use the arrangement comfortably, not merely that it eventually enters after other options disappear.

Make a simple record of which variable changes next: enclosure, tray, litter or location. Keeping the others familiar makes the cat’s response easier to interpret than introducing a new cabinet, new tray and new litter together.
