FELIWAY Optimum is designed to address common signs of stress in cats and kittens. Its patented pheromone formula targets everyday triggers, creating a reassuring environment that helps pets feel secure in their own home. The result is a calmer backdrop for daily routines, helping you and your cat settle into a more predictable rhythm.
With each refill, you can provide up to four weeks of continuous calming support. The diffuser options cover spaces up to 700 square feet, making it suitable for larger rooms or multi‑cat homes. It is easy to use and suitable for cats of all ages, supporting everyday well‑being without fuss.
Plug the diffuser into an open outlet, keeping at least four feet of space for optimal diffusion and pointing the vents upward. In living rooms, bedrooms, and common areas, the steady emission can provide a calming backdrop that supports daily activities and routines for your cat.
FELIWAY diffusers are drug free and non sedating. They are designed to be safe for homes with children and other pets, and the formula does not directly affect people when used as directed. This makes FELIWAY Optimum a practical option for everyday life with cats.
As a widely used option grounded in pheromone science, FELIWAY Optimum has a long track record of veterinary support and real‑world use. Many cat families appreciate a trusted tool that supports a calmer home environment without changing daily routines.
