Shared territory, changes to routine, unfamiliar surroundings, and visitors can be stressors for indoor cats. This refill is designed to support calmer interactions and everyday behavior management, particularly in homes where cats share space. It works with a plug-in diffuser, so you can provide pheromone support in the room where your cats spend time.

What behaviors is the Comfort Zone refill designed to help with?

The pheromone formula is designed to help reduce common stress-related behaviors, including conflict between cats. Cats instinctively recognize the pheromones as a signal that an area is familiar and secure. Most cats begin to show improved behavior within as little as one week, with continued support through regular use.

• Behavior examples include urine marking, scratching, swatting, biting, and fighting.
• Other listed signs include growling, hissing, spitting, screaming, non-playful staring, stalking, chasing, and blocking.

Which diffuser does this refill fit, and how do I use it?

This refill is made for Comfort Zone cat calming diffusers and must be used with a plug-in diffuser. Replace the refill monthly to keep pheromone support consistent; the reusable Comfort Zone diffuser is designed for use for up to 12 months.

• Place the diffuser upright in an open area with four feet (1.2 m) of clearance around it.
• Avoid placing it under shelves, behind furniture, or near vents or windows.

How much space does one diffuser cover?

One diffuser and refill are designed to cover one indoor room, making it possible to focus use where your cats spend the most time. The refill is fragrance-free and drug-free, and the system is designed for easy, mess-free use.

• Comfort Zone has offered cat calming pheromone products for over 20 years.
• The refill meets Intertek electrical safety requirements and is certified to UL standards.

This refill suits indoor cats in multi-cat homes where shared territory, routine changes, new environments, or visitors may contribute to tension. It is intended for use with a Comfort Zone plug-in diffuser, with one room as the coverage area.
