Comfort Zone Multi-Cat Diffuser Refill 2 Pack – 30-Day Calming Pheromones

Calming support for multi-cat homes

Comfort Zone Multi-Cat Diffuser Refills are designed to help ease common signs of stress in homes with several cats. These refills work with all Comfort Zone cat calming pheromone diffusers and are ideal for routine changes, new environments, or visitors. When cats share space or compete for territory, tension can show up as unwanted behaviors. A cat plug-in pheromone diffuser must be used with this product.

Each refill provides 24/7 calming for up to 30 days, helping maintain a steady, calming atmosphere. The fragrance-free, drug-free pheromone formula mirrors a cat’s natural calming signals, which cats instinctively recognize as a cue that an area is safe, familiar, and secure. While results can vary, many households notice calmer behavior within a week of consistent use, with continued benefits over time.

• Two refills that cover one room each for up to 30 days
• Fragrance-free and drug-free pheromone science

How it works in real-life spaces
