Ceva Feliway Optimum Cat Pheromone Refill 48 ml

Ceva Feliway Optimum is a synthetic feline pheromone refill designed for use with the Feliway Optimum diffuser. It contains 48 ml of the Feliway Optimum pheromone complex, which helps reduce stress-related behaviours in cats such as scratching, urine spraying, hiding, and inter-cat tension in multi-cat households.

The formula uses the Feline Pheromone Complex, a blend of pheromone analogues that send calming messages recognised by cats of all ages and breeds. When plugged into a standard electrical outlet via the compatible diffuser, the refill gradually releases pheromones into the surrounding environment, covering an area of approximately 70 square metres. Each 48 ml refill lasts up to 30 days of continuous use.

Feliway Optimum is recommended by veterinary behaviourists for managing situational stress triggers such as moving house, introducing new pets, changes in routine, or the presence of outdoor cats. It is odourless and non-sedating, with no known side effects on cats or other household pets. The refill is compatible only with the Feliway Optimum diffuser — not interchangeable with classic Feliway or Feliway Friends units.
