Is your cat peeing on the bed and carpet or scratching the furniture and door frames? These behaviors can be signs that your cat is stressed. Comfort Zone diffusers dispense a drug-free vapor that mimics a cat's natural calming pheromones to create a calming environment which helps reduce your cat's destructive behaviors. The pheromones are diffused into the air which signal to the cat that the area is safe and familiar, making your cat feel more comfortable. Use the Comfort Zone Calming Diffuser Kit if you see your cat urine spraying or scratching in the home. You can also use the diffuser if you've just adopted a new cat, moving to a new home or even when rearranging your furniture which can be stressful events for cats that can trigger these destructive behaviors. Plug in a diffuser into each room your cat roams or spends the most time. Replace the refill every 30 days and the diffuser unit every 12 months. Our products are safe and certified to U.L standards.
