Will my cat actually use a self-cleaning litter box?

The Good Housekeeping review of the Litter-Robot 4 explicitly calls out transition as the hardest part, and that pattern repeats across r/CatAdvice threads for every brand in this category. Most owners report a 1-4 week adjustment, often easier with kittens and harder with older or skittish cats. Keeping the old manual box available during transition is the most commonly recommended tactic.
