FELIWAY Optimum works by releasing calming messages around the home that provide enhanced serenity for cats. This helps to solve common signs of stress such as scratching, urine spraying, tension and conflict, hiding, and reacting to changes. The new pheromone complex FELIWAY Optimum uses is designed to mimic the natural calming signals cats use to mark an environment as safe. This advanced formula enhances these calming effects, helping cats to feel more secure and relaxed.
