Feliway Diffuser & Refill 48ml A Feliway diffuser can help your cat to deal with new or stressful situations. This can be anything from trips to the vets or a new home environment. cats exhibit certain behaviour such as scratching, meowing, toileting inside and shying away from contact. Whilst a certain amount of apprehension is normal during a stressful environment, extreme anxiety can have a negative effect on your cat. Moving house or a fear of fireworks and thunder can lead to a cat with fearful aggression or anxiety. Feliway uses a synthetic form of the feline facial pheromone, which has a calming affect on cats. The feline facial pheromone is a scent (undetectable to humans) that signals to cats that an area/territory is safe. To use the pheromone diffuser for cats: Plug in the diffuser in the room where your cat spends most of their time. The pheromone will be diffused through the room. Replace the vial with a refill after 4 weeks. Can be used for: Settling a cat into a new home Litterbox training Travelling Trips to the vet Separation problems Fears like thunder and fireworks
