Stressful or unfamiliar situations might provoke fear, anxiety and undesired behaviour in your cat. The Feliway Diffuser is based on a unique formula with natural cat pheromones which alleviate the tension and create a calming and relaxing environment for your feline friend. Simply screw the vial onto the diffuser and plug it into the electric socket. Leave it on for as long as you wish to and create a loving and caring environment for your cat! Common signs of cat anxiety include increased scratching, meowing, toileting inside and shying away from human contact. Left unchecked, high and prolonged anxiety can be extremely harmful to cats. 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. A Feliway Diffuser can help your cat to deal with stressful situations such as thunderstorms, trips to the vet or changing homes. The Feliway Diffuser is very easy to use. Simply plug the diffuser in the room where your cat spends most of his or her time and away it goes. The pheromone will be diffused through the room creating the feeling of a safe environment for your cat. The vial may need replacing with a Feliway Refill after 4 weeks. The diffuser is designed to be left on continuously and will cover a space of 50-70m2. Avoid placing the diffuser behind furniture, doors or curtains or underneath shelves as this can make it less effective. Safe for cats of all ages. If your cat is getting anxious during travel and you can't take the diffuser with you, try Feliway Spray instead. If you already have the diffuser and just need to refill it, you can buy Feliway Refills separately.
