Diffuser set Ceva Feliway Optimum — diffuser + refill for feline pheromone calming

The Ceva Feliway Optimum diffuser set — diffuser + refill for feline pheromone calming provides a continuous, plug-in delivery of synthetic feline appeasing pheromones intended to reduce stress-related behaviours in domestic cats. The set contains an electric diffuser unit and one liquid refill formulated to release pheromones into the immediate environment, supporting calmer interactions, reduced marking and lower anxiety when used as directed in homes and multi-cat households.

Advantages

This diffuser set offers a non-invasive approach to behaviour management by delivering a steady low-level release of calming pheromones. It is designed for continuous operation in a standard mains outlet, requiring minimal user intervention after installation. The liquid refill is formulated for gradual evaporation, providing consistent coverage in the surrounding room area during its effective period.

Suitable for

• Reducing urine marking and scratching related to stress
• Managing inter-cat tension and improving social interactions in multi-cat homes
• Helping cats adjust to changes in the home environment such as new people, visitors, or furniture
• Lowering signs of anxiety during routine stressors like grooming, vet visits preparation, or short separations

When it may not be suitable

The diffuser set is intended as a behavioural support tool and is not a medical treatment for underlying medical conditions. If a cat displays sudden changes in behaviour, aggression, persistent house soiling, or other concerning symptoms, veterinary assessment is recommended before relying solely on pheromone therapy. Results vary by individual animal and environmental factors; some cats may show little or no response.

What to consider before purchase

Usage recommendations

Use the diffuser continuously for at least several weeks to assess effectiveness, and combine with consistent environmental adjustments and positive reinforcement-based behaviour strategies. If no improvement is observed, seek veterinary or qualified behaviourist advice.
