CalmPaws Diffuser is your effortless solution for a more relaxed, happier cat. It diffuses a natural, calming scent — pheromones only cats can detect — like comforting messages assuring them “you’re safe and loved.” It helps reduce stress-driven behaviors like spraying, scratching, litter-box avoidance and hiding, bringing tranquility back to your home.
Pick an open outlet in your cat’s favorite room, twist the refill vial into the diffuser until snug, then plug in and leave it running. Replace the vial every 30 days for continuous calm.
A gentle dual-pheromone blend in a plant-based carrier with no added fragrance or alcohol. The heat-controlled diffuser ensures a steady, even release for about 30 days.
Keep the calm constant and spend less doing it. Save on every automatic refill, shipped right as the previous one empties. Pause or cancel anytime.
