    • How fast will I see results?

      Field study data shows that a lot of cat owners will start to see a significant reduction in stress signs within the first 7 days. However, every cat is unique. Depending on how long the signs of stress have been present and their severity, it may take longer to see the effects. We recommend using FELIWAY Optimum for at least 1 month.

    • How long should I use it?

      FELIWAY Optimum provides a message of enhanced serenity. Most cats will benefit from the permanent presence of this message in your home. The minimum recommended duration is one month.

    • When to use?

      Living with humans can be challenging for cats as we have busy, changing households and routines. FELIWAY Optimum can be used to comfort your cat at home constantly. FELIWAY Optimum can also help:

      • if your cat shows signs like spraying, scratching walls or furniture
      • if your cat shows signs of stress such as hiding, reduced activity, reduced appetite, over grooming
      • if you anticipate changes in your home (e.g. moving home, renovation, redecorating, arrival of a new pet, arrival of a new family member…)
      • if you have 2 or more cats living with you, and they are showing signs of tension such as chasing, blocking or staring
      • if you have 2 or more cats living with you, and they are showing signs of tension such as chasing, blocking or staring
      • if your cats that live together are fighting, even if they have been fighting for a long time
    • Where to use?

      In the room where your cat(s) spends most of their time. Or in the room where tension or conflicts happen most often.

    • Where NOT to use?

      Hallways: Cats spend very little of their time in hallways, so the efficacy would be weaker.(Except if the hallway is the area where scratching or cat spraying is happening most often). Near the litter box: Cats spend very little of their time near their litter box, so the efficacy would be weaker. (If the litter box is in the same room where your cat spends most of their time this is not a problem).If conflict between cats occurs frequently in a hallway, distribution of your cat's’ resources should also be considered within the home to ensure each cat has an easy and free access to a litter box, food and water bowl, resting area, without being potentially blocked by another cat.

    • When NOT to use?

      • If your cat has no access to a clean litter tray, they will urinate in your home, and FELIWAY Optimum will not help in this scenario.
      • If your cat has no access to a scratching post, they will scratch objects in your home instead (because scratching is an essential need of cats), and FELIWAY Optimum will not help.
      • If your cat is urinating, hiding or eating less for medical reasons, FELIWAY Optimum will not help. It is important to consult a veterinarian to rule out any potential medical issues.
      • FELIWAY Optimum will not help in cases of tension or aggression towards owners. In such situations, we recommend consulting your veterinarian or a behaviourist.
      • If your cats do not have access to an individual food/water bowl and litter box, competition for resources remains and the tension between your cats will continue.
    • Where should I plug the diffuser?

      In an electric socket with a minimum clear distance above the diffuser of 1.20m. The oily vapour that carries the FELIWAY Optimum serenity messages rises in a column of warm air above the diffuser. Plug into its own power outlet

    • Where NOT to plug in the diffuser?

      Diffusion will be blocked if the diffuser is plugged in: behind a door, underneath furniture, in any socket without 1.20m clear above it. In a multi-plug or multi-socket adapter. With an international adaptor. With an extension lead

    • How does it work?

      Thanks to the advanced messaging of the New Feline Pheromone Complex, FELIWAY Optimum provides cats with a message of enhanced serenity. This holistic message helps all cats feel more comfortable and secure in their home by providing reassurance, as well as harmony between cats living together.

    • How does it work?

      Cats communicate through natural messages released in the air: “happy messages” (called feline facial pheromones).  

      When comfortable and happy, cats mark their territory as familiar by rubbing their face against corners, furniture, people, or other cats at home. By doing that, they release a message. When present in the environment, these “happy messages” provide calming and comfort to cats.

      When modern life conflicts with their natural needs, cats can feel stressed and anxious. When stressed or anxious they do not mark their environment with these “happy messages” anymore and may pee outside the litter box, scratch or hide as a result.

      FELIWAY CLASSIC provides “happy messages” to cats and makes them feel calm and comfortable at home. By mimicking the natural feline reassuring messages, FELIWAY helps cats happily adjust to pace of modern life, restores calm and may help decrease urine spraying, scratching and hiding.

      • 1 refill lasts up to 30 days
        • It is recommended to replace the refill every 4 weeks. A small amount of liquid will remain in the vial (the vial will never be completely empty because the last few drops of liquid are not enough in contact with the wick to allow the diffusion process)

  • Resolve FELIWAY Diffuser issues

    • How to check proper function of the diffuser?

      When plugged into an outlet, the diffuser will get warm, indicating it is working properly.

    • The diffuser is warm

      The diffuser contains a heating element that diffuses the product. It is designed to be warm to the touch.

    • The level of liquid is not going down

      The diffusion of the liquid from the Diffuser is a very slow process. In normal conditions of use, it is difficult to see any change in the vial over the first week of use. Slight variations will occur depending on air turnover. To make sure your diffuser is working properly, check that:

      • the wick is not broken
      • the device is turned on all the time (sometimes an electrical outlet is controlled by a wall switch)
      • finally, try the device in a different electrical socket
    • Visible mark on your wall or furniture

      The vapor (carrying FELIWAY “messages”) rises in a column of warm air above the diffuser. Sometimes the airflow in the room allows the vapor to re-condense and leave a visible mark. DON’T plug the diffuser under any furniture or object protruding from the wall. There should be at least 5 ft of space above the diffuser.
    • Diffuser and air conditioning?

      Be careful to plug the diffuser away from the air-conditioner, vents, cold air returns, or exhaust fan.

    • Diffuser and open windows?

      Usage with open windows and doors may result in the product not staying within your home. The product also may not last the full expected 30 days. In such a case, a different diffuser location should be considered within the house, targeting the area where the cat spends most of its time.

  • FELIWAY safety

    • For cats

      All FELIWAY products are completely safe for cats when used as recommended.

      FELIWAY products have been used by more than 11 million cats.

    • For kittens

      All FELIWAY products are safe for kittens when used as recommended.

      There is no minimum age for using any of the FELIWAY family of products.

      Kittens are able to perceive “FELIWAY messages” released in the environment and respond accordingly.

    • For humans

      FELIWAY is safe for humans when used as recommended.

      FELIWAY “messages” are specific to cats. They are only perceived by other cats, not by people.

      Diffusers comply with the International Electrotechnical Commission (IEC), European Norms (EN) and Underwriters Laboratories (UL ) required standards. The plastic materials used are self-extinguishing (V2 grade).

      When the diffuser is used continuously, we recommend replacing the diffuser after 6 months of use.

    • For dogs

      FELIWAY is safe for dogs when used as recommended.

      FELIWAY “messages” are specific to cats. They are only perceived by other cats, not by dogs.

    • For caged birds

      Some caged birds are known to have sensitive respiratory systems (in particular Psittacines: parrots, budgerigar, etc.). If you are using FELIWAY CLASSIC or FELIWAY MultiCat we recommend not using a diffuser in the same room as where the bird is housed.

    • For aquarium fish

      FELIWAY is safe for fishes when used as recommended.

      As a precaution, we recommend not using a diffuser in the same room as the aquarium. If the cat spends most of their time in the room with the aquarium, we recommend using an outlet as far from the aquarium as possible. We recommend using a cover over the aquarium. This is a precaution to avoid oily, diffused active ingredients settling on the surface of the water. The components themselves are not classified as toxic for the environment.
