Ceva Feliway Classic Daily and calming well-being for cats Helps reduce the main signs of stress approximately 16 uses 20ml Recommended by veterinarians For transport, Feliway Classic Spray helps significantly reduce signs of stress in kittens and adult cats, such as vomiting, urinary disturbances, defecation, meowing, agitation and salivation. Properties Cats delimit their living space by depositing natural calming messages (scientifically known as cat calming pheromones) on objects around them or on their activity areas. These odorless messages, undetectable by humans and other animals, are perceived only by cats. When a change occurs in the environment in which it lives, the Cat loses its usual orientation and stops marking its territory. Feliway Classic Spray reproduces the properties of these calming messages and helps cats feel calm and safe during transport or travel. Scientifically proven, Feliway Classic Spray 20 mL significantly reduces signs of stress such as vomiting, diarrhea and meowing during transport/travel. Source: Gaultier & al. 1998.
