FELIWAY MultiCat Calming Pheromone Diffuser Refills — 6 Pack, 4-Week Refill, Non-Sedating

If you have more than one cat, episodes of staring, blocking, chasing or fighting can become frequent and stressful for the household. FELIWAY MultiCat uses a synthetic copy of the natural message mother cats release to help groups of cats feel more comfortable around one another. Each refill lasts up to four weeks and one diffuser covers roughly 700 square feet, making it simple to give shared living areas continuous calming support without medication or sedation.

How does FELIWAY MultiCat work to ease tension between cats?

The product delivers a synthetic pheromone into the air that mimics the comforting signal mother cats emit. Cats pick up this message through scent receptors, which can make interactions feel less confrontational and lower visible signs of conflict. It’s a behavioral support tool that complements environmental changes and positive interactions.

• Diffuser emits a continuous pheromone fragrance designed for social harmony.
• Each refill provides up to 4 weeks of coverage per diffuser.
• One diffuser supports about 700 ft² of living space.
• Non‑sedating and formulated for everyday home use.

Where should I place the diffuser for best results?

Place the plug‑in diffuser in a frequently used shared area where your cats interact, such as a living room or kitchen. Use an open outlet with vents pointed upward and leave at least 4 feet of clearance around the unit to allow even distribution. Avoid hiding it behind furniture or in closed cabinets so the pheromone can spread freely.

• Plug into an open wall socket in the main shared room.
• Keep vents pointed upward and allow 4+ feet of clearance.
• Optimal placement is at cat height in busy social spaces.
• Use one diffuser per 700 ft²; add units for additional rooms.

How long until I see an effect and how often do I need to replace refills?

Some cat owners notice calmer interactions within days, though results vary by household and the nature of cat relationships. Each refill lasts up to four weeks under normal conditions, so a 6‑pack gives roughly six months of continuous single‑diffuser support if replaced monthly. For persistent or severe conflict, combine the diffuser with environmental enrichment and consult your veterinarian.

• Possible improvements may appear within days; timing varies.
• Refill duration: up to 4 weeks per bottle.
• 6 refills provide approximately six months of monthly replacement for one diffuser.
• For broader coverage, use additional diffusers in other rooms.

Is FELIWAY MultiCat safe to use around pets and people?

FELIWAY MultiCat is formulated to be safe and non‑sedating; it’s intended for use around cats, kittens, people and most other household pets. It is a behavioral aid rather than a medication, so it should be used according to the label instructions. If you have specific health concerns for a pet, consult your veterinarian before beginning any new behavioral support tool.

• Non‑sedating: supports calm without medication.
• Safe for multi‑pet households when used as directed.
• Follow label instructions for placement and replacement.
• Consult a vet for health‑related questions or severe cases.
