FAQ

Learn more about FELIWAY®

Where should I plug in my FELIWAY® diffuser?

For the best results, you should plug your FELIWAY® diffuser into a properly functioning electrical outlet that has a clear space above it of at least 4ft (1.2m). This is important to ensure the vapor carrying the FELIWAY® messages can rise above the diffuser as a column of warm air.

Where should I NOT plug in my FELIWAY® diffuser?

To ensure your FELIWAY® diffuser can work effectively, do not plug it in:

  • behind a door
  • under furniture
  • in any socket that does not have a clear space of 4ft or 1.20m above it

Your FELIWAY® diffuser should also not be connected:

  • in a multi-plug or multi-outlet adapter
  • with an international adapter
  • in an extension lead

How many FELIWAY® diffusers do I need?

To be as effective as possible, we recommend using one FELIWAY® diffuser per area up to 700sq ft. For a large house, or a house with several floors, use several FELIWAY® diffusers to ensure that each area of the house is covered.

How long do FELIWAY® diffusers last?

One FELIWAY® diffuser refill will last up to 30 days. We recommend replacing the refill every four weeks, even if there is still a small amount of liquid left inside the vial. The vial can never be completely empty as the last drops of liquid are not sufficient for the diffusion process to occur.

With continuous use, a FELIWAY® diffuser lasts six months. After six months have
passed, it’s best to replace the diffuser to ensure optimum effectiveness.

How long does FELIWAY® take to work?

Once your FELIWAY® diffuser is plugged in, allow up to 24 hours for it to become fully functional and for the FELIWAY® calming messages to spread throughout your home. Many cat parents begin to see results within the first seven days. However, each cat is unique and the timing can vary. If you are aware of a situation coming up that may affect your cat, it is best to plug in the FELIWAY® diffuser two to three days in advance to provide the best support.

For more information on how long all our FELIWAY® diffusers take to work, view our full guide here.

Should I unplug my FELIWAY® diffuser at night?

It is important not to unplug or turn off your FELIWAY® diffuser at night. This is when
cats are often awake and at their most active!

For the best results, leave the FELIWAY® diffuser on all the time. Clinical trials show that the diffuser is most effective when used continuously, 24 hours a day, as this allows your cat to continuously perceive the FELIWAY® calming messages.

Can you put FELIWAY® in a regular diffuser?

FELIWAY® refills should never be used with any other electrical device or diffuser. Similarly, FELIWAY® diffusers should never be used with any other cat-calming refill from another company.

What plug do I need for a FELIWAY® diffuser?

FELIWAY® diffusers are supplied with a plug that is compatible with the local
electricity supply of the country in which they were purchased. They cannot be
used in a country with a different standard voltage. They should never be used
with an adapter or a voltage converter as this can lead to serious safety issues. Before use, please check that your diffuser has the correct plug for use in your country, and only use in properly functioning 230-240V electrical sockets.

Can FELIWAY® diffusers be recycled?

FELIWAY® refills are made of recyclable plastic material (PET). The cardboard box can be recycled with your usual paper waste.

This product is covered by the European Directive 2002/96/EC on Waste Electrical and Electronic Equipment (WEEE): WEE/HG0312WZ.

What is the shelf life of FELIWAY®?

Each FELIWAY® refill has a shelf life of 36 months. For more information, check the expiration date shown on the packaging.

How do I know if my FELIWAY® diffuser is working?

When your FELIWAY® diffuser is plugged into an electrical socket, the diffuser will gradually heat up. This indicates that it is working properly.

Why is my FELIWAY® diffuser getting hot?

If your FELIWAY® diffuser is getting hot, this is nothing to worry about! Each diffuser
contains a heating element that diffuses the product, so it is natural for the diffuser to be warm to the touch.

Why is the liquid level on my FELIWAY® diffuser not going down?

If you have noticed the liquid level on your FELIWAY® diffuser is not going down, the
chances are that it actually is, but you just can’t see it! The diffusion of the liquid is a very slow process. When used normally, it is difficult to see
any change in the vial during the first week of use, though slight variations will occur depending on air turnover.

If it has been a number of days and the liquid level still doesn’t appear to have gone down, check that your FELIWAY® diffuser is working properly. To do this, make sure that:

  • the wick is not broken.
  • the device is turned on (sometimes an electrical outlet is controlled by a wall switch).
  • the electrical socket is working (try the device in a different electrical socket to be sure).

Do FELIWAY® diffusers leave a visible mark on walls or furniture?

FELIWAY® diffusers release oily vapors that rise above the
diffuser in a column of warm air. If this air column is blocked (e.g. if the diffuser is under a shelf, table, or furniture) the oil may re-condense, leaving a visible stain. With this in mind, it is important to leave at least
4ft of clear space above the diffuser. DO NOT plug the diffuser under any furniture or object that protrudes from the wall.

Does FELIWAY® work if I have air conditioning?

If you use a FELIWAY® diffuser close to an air conditioner, this may result in diffusion at a faster rate and the product may not last the expected 30 days. Be sure to plug the diffuser away from air conditioners, vents, drafts, or air extractors.

Can I use a FELIWAY® diffuser near an open window?

As with air conditioners, using a FELIWAY® diffuser in a well-ventilated room may result in diffusion at a faster rate and the product running out before the expected 30 days. In this situation, consider placing the diffuser elsewhere in the house, ideally targeting the area where your cat spends the most time.

How fast will I see results?

Many cat owners start to see results for their cat within the first 7 days of use. However, all cats are different. The first signs of improvement may come later depending on the duration and severity of the signs of stress. We recommend using FELIWAY® Optimum for a period of at least 1 month, and ideally use it continuously for enhanced serenity.

How long should I use it for?

FELIWAY® Optimum sends a message of enhanced serenity to your cat. Most cats benefit from the continued use of FELIWAY® Optimum to create a pleasant environment in your home. The minimum recommended duration of use is 1 month.

When should I use it?

Our modern lifestyles are sometimes incompatible with the needs of our cats (e.g. busy schedules, changes in environment and routine). FELIWAY® Optimum can be used to reassure your cat at home constantly. FELIWAY® Optimum can also help in the following situations:
* If your cat is urine spraying, scratching walls or furniture
* If your cat shows signs of stress such as hiding, reduced activity or appetite, or overgrooming
* If you are anticipating changes to your home (e.g. moving house, renovations, redecorating your home, or arrival of a new pet or person into the household)
* If you have two or more cats living with you and they show signs of tension (e.g. chasing, blocking, staring)
* If your cats living together are fighting, even if they have been for some time.

Where should I use it?

In the room where your cat spends the most of their time.

Where NOT to use it?

  • In hallways: cats spend very little time in hallways, so the efficacy would be reduced if used here.
  • Near the litter box: cats spend very little time near their litter tray, so the efficacy would be reduced if used here (if the litter box is in the room where your cat spends the most time, there is no problem plugging it in this room).

When shouldn't I use it?

If your cat is urinating, hiding or has a lack of appetite for medical reasons, FELIWAY® Optimum will not help. It is important to consult a vet to rule out any potential medical issues. It is important to ensure your cat has access to an adequate number of appropriately placed resources.

  • If your cat does not have access to a clean litter box, they will urinate in your home and FELIWAY® Optimum will not help this.
  • If your cat does not have access to a scratching post, they will scratch your walls or furniture (as scratching is a basic need for cats) and FELIWAY® Optimum will not help.
  • FELIWAY® Optimum will not help in cases of tension or even aggression towards owners. In such situations, we recommend consulting your vet or a qualified animal behaviorist.
  • If you have several cats and they do not each have access to their own food/water bowls and litter tray etc, competition for resources remains and tension between your cats will continue.

How does it works?

Cats communicate through natural messages that they release into the environment: pheromones.

When cats feel comfortable and happy, they mark their territory by rubbing their face against corners, furniture, people or other cats at home. By doing this they release a message. When they find these "happy messages" in their environment, cats feel reassured.

When modern life goes against their natural needs, cats do not feel totally comfortable. They no longer release these "happy messages" and start to show signs such as urine spraying, scratching or hiding.

FELIWAY® Classic sends "happy messages" to cats which helps them to feel safe and secure at home. In this way, FELIWAY® Classic helps your cat to adjust to the pace of modern life, supporting their well-being and helping to reduce signs of stress such as urine spraying, scratching or hiding.

How fast will I see results?

Many cat owners start to see results within the first 7 days of use. However, all cats are unique. The first signs of improvement may come later depending on the duration and severity of the cat's behavior. We recommend that you use FELIWAY® Classic for at least 1 month.

How long should I use it?

Most cats will benefit from FELIWAY® Classic being used continuously to create a pleasant environment in your home.

The minimum recommended duration of use is one month.

When should I use it?

  • To comfort your cat in your home
  • If your cat shows stress-related signs, such as urine marking and scratching on walls or furniture that appear in many places

  • If you are planning to make changes in your home (moving, renovation, redecoration, arrival of a new pet, arrival of a new family member...).

Where should I use it?

In the room where your cat spends the most of their time.

Where NOT to use it?

  • In hallways: cats spend very little time in hallways, so the efficacy would be reduced if used here.

  • If your cat does not have access to a scratching post, it will scratch your walls or furniture (as scratching is a basic need for cats) and FELIWAY® Classic will not help.
  • If your cat does not get along with another cat living in the same household, we recommend using FELIWAY Optimum instead.
  • FELIWAY® will not help if there is tension or even aggression towards the owners. In such situations, we recommend that you consult your vet or an animal behaviorist.

How does it work?

After birth, the mother cat sends "harmony messages" to her kittens. When these messages (scientifically called pheromones) are released in the mammary area, they help to ensure that the kittens bond.

FELIWAY® MultiCat transmits "harmony messages" to all cats and helps restore harmony between cats living in the same household.

FELIWAY Friends uses the natural soothing messages of our felines to help your cats live together and helps reduce tension, conflicts and fights.

How fast will I see results?

Many cat owners start to see results within the first 7 days of use. However, all cats are unique. The first signs of improvement may come later depending on the duration and severity of the conflict between your cats. We recommend that you use FELIWAY® MultiCat for at least 1 month.

How long should I use it?

When should I use it?

  • If you have 2 or more cats living together and they show signs of tension such as chasing, blocking or staring.
  • If cats living together are fighting, even if this has been going on for some time.

Where should I use it?

In the room where the cats spend the most time. If this is different for each cat you may need to use multiple diffusers.

Where NOT to use it?

  • In hallways: cats spend very little time in hallways, so the efficacy would be reduced if used here.
    If conflict between your cats often occurs in a hallway, consider the distribution of resources within your home to ensure that each cat has easy and free access to their litter tray, food and water bowls and resting areas without another cat possibly blocking their path.

When NOT to use it?

  • If your cats do not have access to an individual food bowl and litter tray, competition will not resolve and tensions may increase.
  • FELIWAY® MultiCat will not help if there is tension or even aggression towards the owners. In such situations, we recommend that you consult your vet or an animal behaviorist.
  • If the conflict between your cats is accompanied by urine spraying or scratching inside your home, we recommend using FELIWAY® Optimum.

Some species of caged birds are known to have sensitive respiratory systems, particularly those in the psittacine family (parrots, parakeets, etc.).

This precautionary measure is intended to prevent the oily carrier from settling on the surface of the water. The components themselves are not classified as environmentally hazardous.
