| Directions | FELIWAY Optimum heated diffuser and refill provide calming pheromones continually for up to 30 days in a 700 square foot area. We recommend using an additional diffuser if the room is bigger than 700 square feet. We recommend plugging in the FELIWAY Optimum diffuser in the room where you cat spends the most time. Try not to plug the diffuser under items (e.g. shelves) or close to objects (e.g. behind curtain or doors) as this affects efficacy. We do not recommend plugging your diffuser in near your litterbox or in a hallway - your cat likely does not spend as much time in the places as you'd think. Use FELIWAY Optimum each month to create a constant calming environment. Check the diffuser monthly and replace it twice a year (every six months) to guarantee the best effect. Do not use another plugin with FELIWAY Optimum refills. Do not use FELIWAY diffuser with another refill of another brand. Make sure you are using a FELIWAY Optimum diffuser with your FELIWAY Optimum vials and refills. Each FELIWAY Diffuser comes with a plug adapted to the local electric systems. Please do not use this diffuser in a another country that has a different voltage or with an adapter: it may conduct serious security concerns. Make sure that your diffuser has the fitting plug for your country before plugging in. |
