Feliway optimum by Ceva Sac is a product that provides the best peace of mind for the whole family: it helps cats to be calmer in more situations, visibly reducing signs of stress. Recommended by veterinarians. Savings pack of 3 48ml refills. Feliway Optimum helps cats to calm down naturally and feel comfortable and safe at home. Feliway Optimum cat pheromones provide tranquility and promote harmony between cats. It also helps: If your cat urinates around the house, on furniture or walls. If your cat is hiding, less active, has lost its appetite or is excessively grooming itself due to stress. If you are planning changes in your life or home: moving, renovations, painting, the arrival of a new pet or a baby in the family... If several cats live in the same home and there are signs of tension between them such as chasing, staring or blocking. If your cats fight (even if they have been doing so for a long time). How long should I use it? The calm and tranquility created by using Feliway Optimum provides ongoing support for your cat and can be used long-term. This product should be used for at least one month. Where to plug it in? Plug it in the room where your cat spends the most time. You can also plug it in the area where tensions and conflicts usually occur. How does it work? Feliway Optimum conveys a message of calm for your cats as it contains the most advanced Feline Pheromone Complex. Thanks to this holistic message that creates tranquility and peace between cats living together, cats feel more relaxed and safe in their home. Where should the Feliway Optimum diffuser not be plugged in? Near the litter box: Since cats don't spend much time near the litter box, placing it there may lessen the effect. (It's okay if the litter box is in the room where your feline spends most of its time.) In the hallway: Since cats don't spend much time in hallways, placing it there might lessen the effect. (Use it in the hallway only if this is the space where your cat typically urinates or scratches.) Make sure each cat can easily access its litter box, water, food and resting area without risk of being obstructed by another cat to reduce tensions and conflicts between cats. Tips for use Each diffuser covers an area of up to 70m2. We recommend using an additional diffuser if the cat area is larger than 70m2. Don't forget to refill your Feliway Optimum every month to create a constant calming environment. Check your diffuser monthly and refill it twice a year (every 6 months) to ensure the best results. Use only Feliway refills with the Feliway diffuser. Do not use non-Feliway brand refills with the Feliway diffuser or other diffusers for Feliway refills. Each Feliway diffuser comes with a plug adapted to fit local power outlets. Do not use in areas with different voltages or with adapters, as this may cause serious safety issues. Before using the diffuser, check that it has the correct plug for your country. Ready to use: screw the refill into the diffuser and plug it into a socket. Always leave it plugged in to keep the house calm. Avoid plugging the diffuser under shelves, behind doors, curtains or furniture, as it will not work properly. This product is not a sedative or tranquilizer. It is only for cats. Only cats can detect this pheromone. It does not affect dogs or people. Store in a cool, dry place.
