Cats and kittens can’t talk, so they show their stress and discomfort through behaviors like excessive meowing, marking, scratching, and being anti-social. Help your feline friend through their fear or frustration with the Sentry Calming Diffuser for Cats. This plug-in diffuser quickly releases a pheromone into your home to help calm your cat and alleviate unwanted behavior. It’s easy to plug in wherever your cat likes to hang or hide out. Each bottle delivers up to 30 days of pheromone support (refills sold separately). For over a decade, Sentry has worked with pet experts and universities to help pets lead happier, less stressful lives and strengthen their bond with their paw-rents. Better behavior is just around the corner with Sentry.
