We’ve compiled a Q&A guide on how to use synthetic pheromone products to reduce stress and problem behaviors in cats. Learn how to apply them in specific situations—such as urine marking, multi-cat conflicts, and travel anxiety—along with important precautions.

|---|---|---|---|
| Main use | Focused on carrier or specific space | Uniform diffusion throughout the space | Spaces without an outlet |
| Duration of effect | 4–5 hours | About 30 days (per refill) | About 30 days |
| Suitable situation | Clinic visits, moving, short-term stress | Multi-cat households, long-term management | During travel, rooms without an outlet |
| Timing of use | Spray 20 minutes before use | Keep it on at all times | Starting the day before travel |
| Price range | KRW 10,000–18,000 | KRW 20,000–35,000 (including refill) | KRW 15,000–25,000 |

Using it this way can have the opposite effect
Do not spray the product directly onto your cat. Pheromones are designed to disperse into the air and be absorbed through the environment. Spraying it directly around your cat’s face may trigger a fear response. Additionally, avoid using it simultaneously with other room diffusers or essential oils, as this can neutralize its effectiveness and pose a risk of exposure to oils that are toxic to cats. To ensure continued efficacy, replace the refill every 30 days; leaving an empty diffuser in place serves no purpose.

Must-read for households with two or more cats
In multi-cat households, you should place diffusers according to the number of cats. It is recommended to use one diffuser for every 50–70 square meters (approximately 15–21 pyeong). For cats with severe conflicts, installing separate diffusers in each cat's individual space is more effective. Alongside pheromone therapy, it is essential to provide one more food bowl, litter box, and water bowl than the number of cats. Resolving resource competition is key to maximizing the calming effects of pheromones.
