FELIWAY Optimum Cat Calming Diffuser Refills, 2-Pack for Stress Support

FELIWAY Optimum Cat Calming Diffuser Refill is a 2-pack of patented pheromone refills designed to help reduce common signs of cat stress, with up to 4 weeks of support from each refill.

• Two refills, each providing up to 4 weeks of support when used as directed — keep calming support available over time.
• Coverage for areas up to 700 square feet (65 m²) per diffuser — suitable for larger living spaces.
• Patented pheromone formula — helps reduce stress signs and ease tension between cats.
• Cat parents reported a 77% reduction in urine spraying and 72% reduced tension between cats — figures describe reported experiences.
• Non-sedating and suitable for use around cats of all ages, people, and other pets — fits into a shared home.

Changes at home, fearful reactions, urine spraying, scratching, hiding, and tension between cats can all be signs of stress. FELIWAY Optimum is made to provide ongoing pheromone support through a plug-in diffuser, including in homes where more than one cat lives. Individual cats respond differently, and results may vary with other pets and environmental factors.

What signs of stress is FELIWAY Optimum designed to help reduce?

FELIWAY Optimum is designed to help reduce common stress-related behaviors, including urine spraying, scratching, hiding, and fearful reactions to change. Its patented pheromone formula is also intended to ease tension and conflict between cats. Cat parents reported a 77% reduction in urine spraying, while 72% noticed reduced tension between their cats; these reported results are not a guarantee for every cat.

• Support for fearful reactions during changes in the home.
• Help with scratching and hiding associated with stress.
• Support for calmer interactions in homes with multiple cats.

How long does each refill last, and how much space does it cover?

Each refill provides up to 4 weeks of continuous support when used as directed, and one diffuser covers an area up to 700 square feet (65 m²). The two refills in this pack provide a replacement refill when the first one has been used. The plug-in diffuser provides 24/7 support while operating, so the product is intended for ongoing use rather than a single, occasional application.

To use the plug-in diffuser, place it in an open outlet with its vents facing upward and leave at least 4 feet (1.2 m) of clearance. Follow the label instructions for use. Choose an outlet location with the required clear space so the diffuser can operate as directed.

• Two refill units are included in the pack.
• Continuous support is provided when the diffuser is used as directed.
• Leave the diffuser vents facing upward and maintain the stated clearance around it.

Is this refill suitable for kittens and multi-cat homes?

FELIWAY Optimum is suitable for cats of all ages, including kittens, and is non-sedating. It is designed for use around cats, people, and other pets, making it an option for shared households as well as homes with one cat. In multi-cat homes, the pheromone formula is intended to help ease tension between cats; results can vary depending on the animals and their environment.

FELIWAY is the #1 vet-recommended brand based on a survey of 200 veterinarians. Its feline stress work is backed by 30 years of expertise and scientific research. These credentials provide context for the brand and formula, while each cat’s response remains individual.

• Non-sedating support for everyday use as directed.
• Suitable around kittens, adult cats, people, and other pets.
• Results may differ when other pets or environmental factors are present.

This refill pack suits cat households looking for ongoing pheromone support for stress-related behaviors, including homes with more than one cat or cats of different ages. It is intended for use with the plug-in diffuser and is not a one-time treatment; each refill provides up to 4 weeks of support when used as directed.
