The short answer
Calming diffusers release a copy of the facial pheromone cats leave when they rub, which many cats find reassuring. They can help with moves, new pets, scratching and marking from stress, but they work best alongside fixing the cause, and they don't replace a vet visit for sudden behavior changes.
Options
