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.

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.

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

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

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.

• 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.

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.

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.

A lot of cat owners start to see results within the first 7 days with their cat. However, every cat is unique. Depending on how long the signs have been present and how severe the signs may be, it may take longer to see effects.

We recommend using FELIWAY CLASSIC continuously for at least 1 month.

Most of the cats will benefit from continued use of FELIWAY Classic to create a happy environment in your home.

The minimum recommended duration is 1 month.

• To provide constant comfort to your cat at home

• Hallways: Cats spend very little of their time in hallways, so the efficacy would be weaker (Except if the hallway is in the room where urine marking or scratching happens most often)
• Near litter box: Cats spend very little of their time near the litter box. FELIWAY is not a litter box attractant. (If the litter box is in the same room where your cat spends most of their time, it will not prevent your cat from using their litter box)

• Scratching is a natural behavior of cats. Your cat should also have an easily accessible scratching post in the home. FELIWAY CLASSIC will not deter scratching if a scratching post is not provided. If your cat has conflict with another cat living in your home, we recommend using FELIWAY MulitCat instead
• FELIWAY will not help in aggression towards the owners. In such situations, we recommend consulting your veterinarian or a behaviorist

• Use 1 diffuser for an area up to 700 sq. ft.
• You may need to use more than one diffuser for a large or multi-floor home

• 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)
• 1 diffuser heating unit lasts up to 6 months. Replace the heating unit every 6 months to ensure optimum diffusion of the product

• It will take up to 24 hours for the room to become saturated with FELIWAY
• For situations that can be anticipated, you should plug in the diffuser 2-3 days in advance to ensure thorough diffusion in the room

• Don't unplug or switch off the diffuser at night. It takes approximately 24 hours for a room to become saturated with FELIWAY® CLASSIC or FELIWAY® MultiCat. If you unplug the diffuser you will never allow the pheromones to reach the amount needed in the environment to achieve clinical results.
• Leave the diffuser on 24 hours a day. The clinical trials were performed with continuous use of the diffuser (24 hours a day) allowing the cat to constantly perceive the reassuring messages

• FELIWAY refills should only be used with a Ceva diffuser

• The refills are made of recyclable plastic material (PET). Please check with your local recycling facility to determine if you can recycle this product in your area

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

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

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

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.

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

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.

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.

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.
