Frequently Asked Questions
Q1: How long does FELIWAY® Optimum cat calming diffuser take to work?
Ans: When using the FELIWAY Optimum cat calming diffuser, many cat parents see results within seven days. Results vary by cat. Stress severity and duration matter. Some cats show calm behavior later. Continuous use for at least one month is recommended to help reduce cat stress and improve serenity at home.
Q2: When should FELIWAY® Optimum be used for stressed cats?
Ans: FELIWAY® Optimum should be used continuously or for at least one month. Keep the diffuser plugged in 24/7. It helps with urine spraying, scratching furniture, hiding, appetite changes, and overgrooming. It is also useful during home changes or multi-cat household tension.
Q3: Where should FELIWAY® Optimum diffuser be placed in the home?
Ans: FELIWAY® Optimum should be placed in the room where your cat spends most time. Use a working electrical socket. Keep four feet of space above the diffuser. This placement allows calming pheromone vapor to spread properly and support stress relief for cats.
Q4: Where should FELIWAY® Optimum NOT be used for best results?
Ans: FELIWAY® Optimum should not be used in hallways or near litter boxes. Cats spend little time there. This reduces effectiveness. If the litter box is in the main living area, placing the diffuser in that room is acceptable and will not reduce performance.
