FELIWAY Cat Calming Pheromone Diffuser Refill — 1 Pack, 4-Week Stress Relief for Cats

FELIWAY Classic Cat Calming Diffuser Refill is a plug-in pheromone refill that helps reduce common signs of stress in cats—like spraying, scratching, and hiding—by releasing calming feline pheromone signals for up to four weeks.

When life at home feels unsettled for your cat — new people, moved furniture, guests, or changes in routine — many cats respond with stress behaviors. FELIWAY Classic uses a synthetic copy of the natural feline facial pheromone to recreate familiar calming cues. Insert the refill into a compatible FELIWAY diffuser (diffuser sold separately) and it disperses continuously to make shared living spaces feel more reassuring to cats.

How quickly will I notice a change in my cat’s behavior?

Responses vary by cat and situation, but many cat owners observe improvements within a few days to a few weeks. Consistent use in the same room gives the best chance to reduce stress-related behaviors over time.

• Start in the room where your cat spends most time.
• Allow continuous use for at least 2–4 weeks before judging effectiveness.
• Combine with environmental management for faster results.

Where should I place the refill and how large an area does it cover?

The refill fits into a plug-in diffuser unit; place the diffuser in an open wall outlet with vents facing upward and 4+ feet of clearance around it. One refill provides calming coverage for up to about 700 square feet of living space.

• Use a central room or the specific room with most stress signs.
• Avoid concealing it behind furniture or low shelves.
• Use additional diffusers for larger homes or multiple problem areas.

Is FELIWAY Classic safe for households with children and other pets?

FELIWAY Classic is formulated to be non-sedating and is safe to use around cats, kittens, people, and other pets when used as directed. It delivers a behavioral cue rather than a drug, helping cats feel more comfortable without causing drowsiness.

• Not a medication—works through pheromone signaling.
• No known sedative effects on cats or humans.
• Follow label instructions and keep out of reach of children.

How long does each refill last, and when should I replace it?

Each refill is designed to provide roughly four weeks of continual release when used with a FELIWAY diffuser. Replace the refill every four weeks for ongoing support, especially during prolonged stressors like moving or multi-cat introductions.

• One refill ≈ 4 weeks of continuous use.
• Replace promptly for uninterrupted calming benefits.
• Use extra refills in multi-room situations or long-term stress.

Who this product is for: FELIWAY Classic Cat Calming Diffuser Refill is intended for cat owners who want a non-pharmaceutical, easy-to-use option to help reduce stress-related behaviors. It's suited for single-cat homes or multi-cat households experiencing scratching, urine spraying, hiding, or anxiety triggered by environmental changes. Veterinarians commonly recommend FELIWAY as part of a multi-faceted approach to improve feline welfare; use it alongside environmental adjustments and veterinary advice for best outcomes.
