Feliway Friends Refill 48ml is a replacement refill for the Feliway Friends diffuser, providing 30 days of the cat appeasing pheromone that reduces tension between cats in multi-cat households.

The refill contains the synthetic cat appeasing pheromone (different from Feliway Classic's facial pheromone) that specifically targets inter-cat conflict. Replace monthly for continuous coverage. Compatible with Feliway Friends diffuser units. Does not replace Feliway Classic for individual cat stress — the two products address different behavioural issues.

Multi-cat household owners who see results from Feliway Friends need to maintain continuous coverage for lasting effect. Monthly refill replacement ensures the calming pheromone doesn't lapse.
