How does FELIWAY® Classic work?

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

The “happy messages” that FELIWAY® Classic uses are the same messages cats release into the environment as a means of communication. These are known as pheromones. When cats feel comfortable and happy, they release these pheromones by rubbing their face against furniture, other household objects, surfaces, people, or even other cats at home. When they later come back across these messages in their environment, this helps cats to feel reassured.

When modern life goes against a cat’s natural needs, they may not feel totally
comfortable and may no longer release these messages. Instead, they may begin
to show signs of discomfort such as urine spraying, scratching, or hiding. So,
by mimicking the “happy messages”, FELIWAY® Classic can help cats to feel comfortable and secure once again.

How long does FELIWAY® Classic take to work?

Many cat parents start to see results within the first seven days of using FELIWAY® Classic. However, all cats are unique and results can vary. The first signs of your cat feeling more comfortable and secure may come later depending on the duration and severity of their behavior. We recommend that you use FELIWAY® Classic for at least one month to see the best results.

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

How long should I use FELIWAY® Classic for?

Most cats will benefit from FELIWAY® Classic being used continuously
to create a pleasant environment in your home. The minimum recommended duration of use for FELIWAY® Classic is one month.

When should I use FELIWAY® Classic?

You should use FELIWAY® Classic to comfort your cat when:

  • Your cat shows stress-related signs, such as urine marking or scratching on walls or furniture.
  • Your cat shows signs of unhappiness (e.g. hiding, low activity, lack of appetite, excessive grooming, etc.).
  • You are planning to make changes in your home (e.g. moving, renovation, decoration, arrival of a new pet, arrival of a new family member, etc.).

Where should I use FELIWAY® Classic?

FELIWAY® Classic should be used in the room where your cat spends the most amount of time. Plug the diffuser into a properly functioning electrical socket that has clear space above it of at least 4ft (1.2m). This allows the oily vapor that carries the “happy messages” to rise above the diffuser in a column of warm air and into the surrounding environment.

What situations will FELIWAY® Classic not work in?

If your cat is urinating, hiding, or has a lack of appetite for medical reasons,
FELIWAY® Classic will not help. In these situations, it is important to consult a vet to rule out any potential medical issues.

Other situations in which FELIWAY® Classic is not an appropriate
solution include:

  • If your cat is urinating in your home but does not have access to a clean litter box.
  • If your cat is scratching your walls or furniture but does not have access to a scratching post.
  • If your cat does not get along with another cat living in the same household (we recommend using FELIWAY® MultiCat instead).
  • If there is tension or even aggression towards a cat’s humans (we recommend that you consult your vet or an animal behaviorist).

In these situations, it is important to ensure your cat has access to an adequate number of appropriately placed resources.

How to Use FELIWAY® Classic ?

Easy to use

  • Just plug and play: screw the vial onto the diffuser unit and plug it into an outlet with the diffuser vents UP
  • Then leave the diffuser plugged in continuously

Good to know

  • Each diffuser refill covers an area up to 700 sq. ft.
  • Avoid plugging in the diffuser under shelves, behind doors, behind curtains, behind furniture. This will impair diffusion


  • FELIWAY® Classic mimics the natural calming messages known as pheromones that your cat produces to help your cat feel more comfortable and secure to reduce signs of stress
  • Ensure continuous comfort to your cat by using a FELIWAY® CLASSIC Refill every month
  • The diffuser should be checked monthly and replaced every six months to ensure optimum effect
