The kit pairs an electric plug-in diffuser with a liquid refill vial that releases a synthetic version of the pheromone a mother cat produces to help kittens bond and feel secure. Once plugged into a standard outlet, the diffuser warms the liquid so the pheromone disperses continuously into the surrounding air. The diffuser is designed to cover an open area of up to 700 square feet and is intended to run around the clock. The included refill vial is built to last about 30 days under typical conditions, after which it can be replaced with a new refill vial to keep the diffuser running. Placement is best in the room or rooms where the cats spend the most time, away from shelves, curtains, doors, or furniture that could block airflow. No assembly beyond plugging in the unit is required, and the diffuser itself is intended to be replaced periodically after extended use.
