FELIWAY Cat Calming Diffuser Refills — 6‑Pack plug‑in refills, 4‑week coverage, covers 700 sq ft

FELIWAY Optimum Refill is a plug‑in pheromone solution that helps reduce common signs of stress in cats, providing up to four weeks of continuous calming support per refill.

If your cat is showing signs of anxiety — such as urine spraying, excessive scratching, hiding, or tension with other cats — FELIWAY Optimum delivers a patented pheromone formula designed to promote a calmer, more secure environment. Each refill lasts up to four weeks and covers areas up to 700 square feet, making this 6‑pack a convenient option for single large rooms, multiple rooms, or to keep a steady supply on hand for ongoing support.

How quickly will I see my cat respond to FELIWAY Optimum?

Response time varies by individual cat and by the type of behavior, but many owners notice changes within days for some behaviors and a few weeks for patterns like spraying. For best results, use continuously and place the diffuser in an open outlet near the area where stress behaviors occur.

• Typical onset: days to weeks depending on behavior
• Continuous use recommended for persistent issues
• Each refill delivers up to 4 weeks of coverage
• Covers rooms up to approximately 700 sq ft

Will this help if I have multiple cats living together?

Yes—FELIWAY Optimum is formulated to reduce tension and promote more harmonious interactions in multi‑cat households. It targets stress cues that commonly lead to conflict, so many owners report fewer aggressive encounters and calmer cohabitation.

• Reduces visible tension between cats in many homes
• Supports calmer social cues and interactions
• Can be used in shared living areas and corridors
• Safe for use around cats, kittens, people, and other pets when used as directed

How do I use the diffuser refill and where should it be placed?

Using FELIWAY Optimum refills is simple: insert the refill into the compatible FELIWAY plug‑in diffuser, then plug into an unobstructed outlet with vents pointing upward. Allow at least four feet of clearance and keep it in the area where the cat spends time or where unwanted behaviors appear.

• Plug into an open outlet with vents pointing up
• Leave at least 4 feet of clearance around the diffuser
• Replace every 4 weeks for continuous support
• One refill covers up to 700 sq ft

Is FELIWAY Optimum safe for my household?

FELIWAY Optimum is a non‑sedating pheromone product intended to support feline well‑being; it is designed for use around cats, kittens, people, and other pets when directions are followed. It’s not a medication, and outcomes depend on each cat and its environment.

• Non‑sedating and for environmental use only
• Follow label instructions for safe, effective placement
• Often used alongside behavioral and environmental adjustments
• Not a substitute for veterinary care when needed

Who is this for? FELIWAY Optimum 6‑pack refills are ideal for cat owners seeking an ongoing, hassle‑free approach to reducing stress‑related behaviors across large rooms or multiple areas. It suits households with single or multiple cats, owners managing changes (new pets, moves, visitors), and anyone who prefers a continuous, plug‑in option to help their cats feel more secure. Keep expectations realistic: results vary with each cat and work best combined with supportive environmental changes.
