These refills pair with all Comfort Zone cat calming pheromone diffusers and are ideal for cats experiencing everyday stressors such as changes in routine, new environments, unfamiliar visitors, or time spent alone. These refills pair with all Comfort Zone cat calming pheromone diffuser products to provide continuous, reliable support. A cat plug in pheromone diffuser must be used with this product.

Each refill provides 24/7 calming support for up to 30 days, helping maintain a consistent calming environment. The fragrance-free, drug-free pheromone formula mimics a cat's natural calming pheromones, which cats instinctively recognize as a signal that their space is safe, familiar, and secure. These refills help reduce behaviors commonly associated with cat stress, including urine marking, scratching, or other stress-related behaviors. Most cats begin to show improved behavior within as little as one week, with continued benefits through regular use. Each diffuser and refill is designed to cover one room, making it easy to target areas where your cat spends the most time.

Easy to use and mess-free, Comfort Zone Cat Calming Diffuser Refills are expert recommended and tested to meet electrical safety standards, offering peace of mind for everyday use. For best results, plug the diffuser upright in an open area with four feet of clearance around the unit, and avoid placing it under shelves, behind furniture, or near vents or windows. Replace refills monthly to help provide continuous calming support and promote a more comfortable, reduced stress home for your cat.
