Feliway Diffuser and Refill is a plug-in pheromone diffuser for cats that releases a synthetic copy of the feline facial pheromone — the scent cats leave when they rub their face against furniture to mark an area as safe. It is designed to reduce stress-related behaviours like scratching, spraying, and hiding in multi-cat or change-prone households.

The diffuser plugs into a standard power outlet and covers an area of approximately 70 square metres for up to 30 days per refill. The synthetic pheromone is odourless to humans and other animals, and works continuously in the background. The starter kit includes the diffuser unit and one 48ml refill vial. Suitable for use around kittens and adult cats of all ages.

Feliway has been the most widely recommended pheromone product for cats in Australian vet clinics for over two decades, and owners dealing with environmental stress — new pets, house moves, renovations, or inter-cat tension — tend to see results within the first week of use.
