When a cat feels safe in its environment, it rubs its head against the furniture, the corners of walls or the bottom of the curtains, leaving substances called facial pheromones. These pheromones convey a message of well-being, calm & absence of stress. When there are changes in the cats environment (such as visits to the vets, return from hospitals, moving house, new arrivals, rearrangement of furniture), or if the cat is scared, a state of disquiet or stress may develop. This state can be conveyed by changes in behaviour, such as urine marking, or vertical scratching, loss of appetite, refusal to play & to interact. In these situations Feliway diffuser can be used to restore the natural balance. Feliway diffuser is a safe solution of feline facial pheromone. Feliway diffuser mimics the cats facial pheromones, creating a state of well being & calm. Each pack contains one diffuser & one 48ml vial.
