Sentry Calming Collars use a pheromone that mimics the one mother cats produce to calm their kittens, and are clinically proven to reduce or eliminate stress-related behavior such as inappropriate marking, destructive behavior, clawing and anti-social behavior. Collars help alleviate problem behaviors triggered by travel, thunderstorms, fireworks and new social situations, and release calming pheromones for 30 days.

Caution: remove the collar before shampooing your cat and replace it after the cats coat is dry. Do not use collar on cats with skin lesions. This is not a pharmacautical product.
