• One diffuser and one refill for one room — target the area where your cats spend the most time.

When cats share territory, resources, and daily routines, tension may show up as conflict or unwanted behavior around the home. This diffuser is designed for multi-cat households dealing with those stress-related behaviors, including tension linked to changes in routine. Use it in a room where your cats spend time to provide ongoing support in that space.

Which cat behaviors is the diffuser designed to help with?

Comfort Zone Multi Cat Calming is designed to help reduce aggressive behavior between cats and support relief from urine marking and scratching. Signs of conflict can include swatting, biting, fighting, hissing, growling, spitting, screaming, chasing, blocking access, stalking, and staring in a non-playful way. Urinating outside the litter box, urine marking, and spraying are also behaviors the diffuser is intended to address. Most cats show improved behavior as soon as one week, while results can vary by cat and household.

• For tension that appears during shared access to territory or resources.
• For households noticing scratching or urine marking alongside conflict between cats.

How does the pheromone diffuser work?

The plug-in releases a continuous mist that mimics natural feline pheromones, which cats instinctively recognize as familiar and reassuring. When cats feel more secure, their interactions may become calmer and more predictable. The diffuser operates quietly, and its low-profile design is intended to sit discreetly in the home. The formula contains no drugs or fragrance, making it suitable for ongoing use without adding a scented product to the room.

• Designed for continuous use rather than a one-time application.
• Use Comfort Zone Multi-Cat Diffuser Refills to continue the calming support.

Where should I plug in the diffuser?

Plug the unit upright into a standard outlet in an open area, leaving four feet (1.2 m) of clearance around it. Keep it away from shelves, furniture, vents, and windows so the surrounding space remains open. The diffuser has an open bottom outlet design for use with standard outlets, and the device is tested to meet electrical safety standards.

• Place it in a room your cats use frequently.
• Avoid positioning it behind furniture or beneath shelves.
• Keep it away from air vents and windows.

What is included, and when should I replace the refill?

The starter kit contains one diffuser and one multi-cat pheromone refill, with each designed to cover one room. Replace the refill every 30 days for continuous support. Comfort Zone Multi-Cat Diffuser Refills are available in packs of 1, 2, 3, and 6, so you can choose a pack size for your refill needs. Comfort Zone has provided care with cat-calming pheromones for over 20 years and the product is vet recommended.

• Starter kit contents: one diffuser and one refill.
• Refill choices: 1-, 2-, 3-, and 6-count packs.

This kit is suited to cat households looking for ongoing, room-based support for tension between cats, including conflict and urine marking. It is intended for multi-cat calming support in the room where the diffuser is plugged in, with refills replaced every 30 days.
