FELIWAY Optimum Cat Calming Diffuser Refill, 3-Pack for Ongoing Stress Support

FELIWAY Optimum is a patented pheromone refill for supporting calmer behavior in cats, with three refills providing up to four weeks of continuous support each when used as directed.

• Patented pheromone formula — helps reduce common signs of stress in cats.
• Three-refill pack — keeps replacement refills together for ongoing use.
• Non-sedating formula — supports calm without sedating cats.
• Suitable for cats of all ages — made for use around kittens and adult cats.
• Designed for cats showing multiple stress signs — supports calmer interactions in multi-cat homes.

Changes at home, fearful situations, and tension between cats can show up as behaviors that are difficult for a household to manage. FELIWAY Optimum is designed to help reduce these common signs of cat stress and support a more settled home environment. FELIWAY calls it its best option for reducing common stress signs, based on a survey of 200 veterinarians. Individual cats may respond differently, and results can vary with other pets and environmental factors.

Which signs of stress is FELIWAY Optimum designed to help with?

FELIWAY Optimum is designed to help reduce urine spraying, scratching, hiding, fearful reactions to change, and tension between cats. Cat parents reported a 77% reduction in urine spraying, while 72% noticed reduced tension between their cats. These reported outcomes are not a guarantee for an individual cat; the brand notes that every cat is unique and that results may depend on the home environment.

The patented pheromone formula is intended to help cats feel more secure in everyday situations and during changes. The product is also positioned for a wider range of stress signs and situations, including conflict in homes with more than one cat.

• Behavioral signs addressed include spraying, scratching, hiding, and fearful reactions.
• Designed to support calmer interactions between cats living together.
• Individual results may vary with other pets and environmental factors.

How does the calming diffuser work, and who can be around it?

When used as directed, the plug-in diffuser provides continuous support around the clock through its pheromone formula. It is non-sedating and intended for use around cats, kittens, people, and other pets. FELIWAY Optimum is suitable for cats of all ages, making it an option for households with cats at different life stages.

The refill is used with a FELIWAY Optimum plug-in diffuser. For setup, plug the diffuser into an open outlet with its vents facing upward and leave at least 4 ft (1.2 m) of clearance. Follow the label instructions for use.

• Use the refill with a FELIWAY Optimum plug-in diffuser.

How long does each refill last, and what area does it cover?

Each refill provides up to four weeks of continuous calming support and covers an area up to 700 sq ft (65 m²) when used as directed. This coverage makes the diffuser suitable for larger living areas as well as everyday use at home. The three-pack contains three refills; each refill has its own stated duration and coverage.

• Coverage is up to 700 sq ft (65 m²) per diffuser.
• Support is continuous when the diffuser is used as directed.
• Use the label instructions to guide setup and use.

FELIWAY Optimum is suited to cat households looking for pheromone-based support for behaviors such as spraying, scratching, fear, or tension between cats. It is especially relevant when a household wants a non-sedating option for cats of different ages and shared living spaces. Its patented formula, continuous diffuser use, and refill format make it a practical fit for supporting calmer everyday routines.
