Feliway Classic Refill 48ml is a replacement refill for the Feliway plug-in diffuser. Each refill provides 30 days of continuous synthetic feline facial pheromone release.

Simply unscrew the empty refill from the diffuser unit and replace with the new 48ml vial. No need to replace the diffuser unit itself. Maintains continuous calming pheromone coverage when replaced monthly. Compatible with all Feliway Classic diffuser units. Store unused refills at room temperature.

Ongoing pheromone therapy requires consistent monthly refill replacement. Purchasing refills separately from the diffuser unit is the most cost-effective way to maintain continuous calming coverage.
