Frequently asked questions

General questions about Feliway and pheromones

What pheromone is in Feliway?

The pheromone in Feliway is an exact copy of the natural feline facial pheromone that happy cats use to mark their territory as safe and secure. Cats release this pheromone by rubbing their cheeks against walls, furniture and people when they feel comfortable in their environment.

Will Feliway affect humans or other animals in my home?

Since pheromones are species-specific, the feline pheromone in Feliway will affect only cats and will have no effect on humans or other pets in the home.

Can I use Feliway with a young kitten or senior cat?

Yes, there is no minimum or maximum age for using Feliway. Cats of all ages are able to detect pheromones in the environment and respond subconsciously to the message they send.

Can I use Feliway and Adaptil in the same household at the same time?

Yes, the pheromones in each product are species-specific. The feline facial pheromone in Feliway will only affect cats and the dog appeasing pheromone in Adaptil will only affect dogs. 

How long should I use Feliway?

It depends on the reason you’re using Feliway. The minimum recommended duration for most situations is one month. Some situations such as recurring feline idiopathic cystitis (FIC)—commonly known as bladder or urinary tract issues—might benefit from permanent use. For short-term situations such as car travel or vet visits, Feliway Spray can be applied to cat carriers and other surfaces every 4 to 5 hours as needed.

What type of behaviour problems will not be helped by Feliway?

If the behaviour is unrelated to stress—for example, house soiling due to unclean or too few litter boxes, normal scratching or claw sharpening, or an underlying medical disease—Feliway will not resolve the cause of the issue and additional environmental modifications may be required. Always consult a veterinarian to rule out potential medical issues that may be leading to unwanted behaviour.

Note also that Feliway® can help in multi-cat households where there is tension between cats, by decreasing overall stress. But Feliway® is not indicated in case of recognized aggression between cats (with fights, attacks or wounding) or towards owners. In such situations, consulting your veterinarian or a behaviorist is strongly recommended. 

What is the best way to clean up after urine marking in the home?

First and foremost, always check with your veterinarian to rule out any medical issues for the behaviour. Thoroughly clean the marked areas with an enzymatic cleaner and allow to dry. Never use ammonia, bleach, vinegar or other strongly scented products as the unfamiliar smell may encourage remarking. When dry, apply 8 pumps of Feliway Spray to each marked area. Reapply spray daily for 3 to 4 weeks to reduce the likelihood of remarking.

Which Feliway product should I use for my cat(s)?

Feliway Diffusers are ideal for long-term, continuous use in the home and other indoor environments. Feliway Spray is ideal for short-term or targeted support at home or on the go. For some situations, such as urine marking or vertical scratching, combining both a Feliway Diffuser and Feliway Spray will have the best results. For more information, please refer to the “How to use Feliway” recommendations in the “What is Feliway?” section of this website.

What kind of environmental modifications do you recommend?

Depending on the situation, environmental modifications may be required in addition to Feliway.

In multicat households, competition for litter boxes and other resources can cause stress and may lead to unwanted behaviours.

Ensure you have one litter box per cat, plus one extra, located in different areas of the home.

Provide multiple food, water and rest areas to reduce competition between cats.

For scratching issues, use Feliway Spray on the scratched surfaces and also provide a scratching post in a nearby location to help redirect the unwanted behaviour. 

Can Feliway be used in multicat households?

Absolutely. In multicat households Feliway can help ease new introductions and reduce tension between cats by decreasing overall stress in the environment. In the case of direct aggression between cats (fights, attacks or wounding) or toward owners, consulting your veterinarian or a feline behaviourist is strongly recommended. 

Using Feliway Diffusers and Refills

Where should I plug in the Feliway Diffuser?

Plug the diffuser in an open area where your cat spends most of its time.

Avoid placing the diffuser near open windows, air vents or under tables or shelves.

Each diffuser covers up to 70m² (750 ft²). More than one diffuser may be required in large or multi-floor homes.

Why should I avoid plugging in a Feliway Diffuser under furniture?

A minimum of clear distance of 4 ft (1.20 m) should be left above and around the diffuser to ensure proper diffusion of pheromones. The warm, oil-based vapour that carries the active ingredients in Feliway rises upward above the diffuser. This vapour may be blocked or may re-condense and leave a visible mark on surfaces above the diffuser if the diffuser is improperly placed.

Should I place a Feliway Diffuser in the hallway?

Feliway Diffusers should be plugged in open areas where your cat spends most of its time or where the problem is occurring. Since cats typically don’t spend a lot of time in the hallway, placing a diffuser in this location is not recommended. The exception would be if the problem, such as marking behaviour or conflict, was occurring in the hallway. In those cases, environmental modifications should also be considered to ensure key pathways to/from litter boxes, food, water and rest areas are not blocked and that resources are appropriately distributed throughout the house.

Should I place a Feliway Diffuser near the litter box?

Feliway Diffusers should be plugged in open areas where your cat spends most of its time or where the problem is occurring. Since cats rarely spend most of their time near the litter box, placing a diffuser in this location or using Feliway Spray on the litter box is not recommended—especially since cats don’t normally mark the litter box with facial pheromones. If, however, your cat spends a lot of time in this room, you can plug a diffuser in this location preferably a good distance away from the litter box.

Will a Feliway Diffuser keep my cat from using the litter box if it’s in the same room?

No, the pheromone in Feliway will not prevent your cat from using the litter box. The diffuser should be plugged in an open area where your cat spends most of its time or where the problem is occurring. In some cases, this may be the room where the litter box is located.

Should I unplug the Feliway Diffuser at night?

No, the diffuser should be plugged in continuously day and night. Frequent unplugging will prevent the diffuser from working properly as it can take up to 24 hours for full diffusion of the pheromone.

How long does the diffuser device last?

Diffuser heads should be inspected monthly and replaced after 6 months or 6 refills for best results.

How long do refills last?

Each refill lasts up to 30 days.

Why isn’t the level of liquid in my Feliway Diffuser going down?

The diffusion of liquid from the Feliway Diffuser is a very slow process. Under normal conditions, it can be difficult to see any change in the Refill level over the first week of use. Slight variations will also 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 at all times (sometimes an electrical outlet is controlled by a wall switch)

- the device is warm (the diffuser will naturally heat up while it's working)

- you are using the correct refill with the correct diffuser

Finally, try the device in a different electrical socket.

Do I need to change the refill after 30 days even if the liquid hasn’t run out?

We recommend replacing the refill after 30 days of continuous use, with or without a small amount of liquid remaining in the refill. Some refills may last slightly longer than 30 days due to differences in location and air turnover; however, since the last few millimeters of liquid are not in direct contact with the wick the liquid may never completely run out. 

How long will it take for Feliway to be diffused throughout the area?

Allow up to 24 hours for the diffuser to become fully functional. This will ensure the wick is completely saturated and Feliway is diffused throughout the area. For stressful events that can be anticipated, it’s a good idea to plug in a Feliway Diffuser 2 to 3 days before the event.

How long will it take to see an effect on my cat(s)?

The Feliway Diffuser is fully functional within 24 hours of plugging it in. The effect on the cat(s) will depend on the nature, extent and duration of the problem for which Feliway is used. Signs of improvement are typically seen within the first week of use, with further improvement in subsequent weeks. We recommend using the Feliway Diffuser continuously for at least one month.

Are Feliway Diffusers safe?

Yes. The Adaptil Diffuser is constructed with self-extinguishing plastic materials and complies with the International Electro technical commission (IEC), European (EN) and UL required standards.

If the diffuser device is used continuously, we recommend that it is replaced after 6 months of use for best results.

Can I plug a Feliway Diffuser in a room where there are caged birds?

In most cases this is not an issue; however, some birds such as parrots and budgies are known to have sensitive respiratory systems. As a precaution, we recommend plugging the Feliway Diffuser in a different room.

Can I plug a Feliway Diffuser in a room with an aquarium?

As with any in-home diffuser, we recommend placing the Feliway Diffuser in a room that does not have an aquarium. If the cat spends most of their time in this room, we recommend using an outlet as far away from the aquarium as possible. This is only a precaution to prevent the oil-based vapour from settling on the surface of the water. The components themselves are not classified as toxic.

Can I use a Feliway Diffuser at the same time as an air-conditioner?

Yes, you can use a Feliway Diffuser in a house or a vet clinic with an air-conditioner. We recommend plugging the diffuser in a location away from the air-conditioner, vents, cold air returns, or exhaust fan, while still targeting the area where your cat spends most of its time.

What is the surface area covered by a Feliway Diffuser?

Each diffuser covers up to 70m² (750ft²). More than one diffuser may be required in large or multi-floor homes, or if more than one room is affected by marking behaviours.

Do Feliway Refills fit other plug-in diffuser systems?

Feliway Refills should never be used with other non-Ceva diffusers and Feliway Diffusers should never be used other non-Ceva refills. 

How can I tell if my Feliway Diffuser is turned on or working?

When the diffuser is plugged into an outlet, the diffuser head will feel warm to the touch.

Can I use a Feliway Diffuser while leaving windows or doors open?

Yes, you can use a Feliway Diffuser in a house or vet clinic with open windows or doors; however, the higher air turnover rate may cause your refill to run out sooner. We recommend plugging the diffuser in a location away from open doors and windows, while still targeting the area where your cat spends most of its time.

Are Feliway Refills recyclable?

The refill bottles are made of recyclable plastic material commonly accepted by most local recycling programs.

Is it safe to use a Feliway Diffuser in my home if I am pregnant?

You may continue using your diffuser. According to the toxicological data on the components of our products, no particular risk is expected following inhalation of the pheromone products when used as recommended. Particularly with pregnant women, the available toxicological data on laboratory animal species show that neither a teratogenic nor fetotoxic effect has been associated with the use of a Feliway Diffuser.  

As a precaution for sensitive people, it is not recommended to plug a Feliway Diffuser in a non-ventilated room where people spend most of their time, and in particular not in bedrooms.

Using Feliway Spray

How do I use Feliway Spray?

Always apply Feliway Spray to an object* or surface. Do not spray the air and do not spray your cat.

  • Apply 8 pumps of Feliway Spray to the desired object or surface (car, carrier, bedding, table for medical examination, etc.)
  • Wait 15 minutes before introducing your cat to the applied area
  • Reapply Feliway Spray every 4 to 5 hours, as needed

*Note: Feliway Spray should not be used on objects intended for scratching, such as a scratching post.

Should I apply Feliway Spray directly on my cat?

Feliway Spray should not be applied directly on your cat.

Always apply Feliway Spray to an object* or surface. Do not spray the air and do not spray your cat.

*Feliway Spray should not be used on objects intended for scratching, such as scratching posts.

How long will it take to have an effect on the cat? How long will the effect last for?

Feliway Spray is proven to have an almost immediate effect, lasting 4 to 5 hours.

If my cat travels by car for a long journey, how often should I use Feliway Spray?

Each application of Feliway Spray lasts 4 to 5 hours. For long car rides, you may wish to reapply Feliway Spray after this time.

Be sure to remove your cat from the carrier before applying Feliway Spray and wait 15 minutes before placing your cat back inside. Alternatively, you can spray a towel, wait 15 minutes, and then place the towel in the carrier.

Can I use Feliway to reduce motion sickness during car travel?

Feliway spray is indicated to relieve manifestations of stress during transport, including vomiting. Feliway spray has been clinically proven to significantly improve stress-related behaviours such as vomiting, urination, defecation but also meowing, agitation and salivation, compared to cats exposed to a placebo spray.

However, Feliway is not indicated against motion sickness when traveling by car. For this reason, we recommend the cat should not have eaten for at least 6 hours prior to travel to avoid nausea and vomiting, but do not limit water before traveling.

In addition, waiting for at least 15 minutes after spraying Feliway before putting the cat inside its carrier, as recommended, is important to avoid the cat being upset by the alcohol from the spray.

Should I spray Feliway on a scratching post to encourage my cat to use it and prevent him from scratching my furniture?

No, Feliway Spray should not be used on objects that you want your cat to scratch, e.g., a scratching post.

Instead Feliway should be used to help prevent or deter your cat from scratching. For more information, please refer to the Scratching section of this website.

Is the Feliway spray bottle recyclable?

Yes. The new Ceva pheromone sprays are made of recyclable plastic material.

Does Feliway Spray stain?

Feliway Spray is an alcohol-based product and should not stain.

We recommend testing on an inconspicuous area if you have any concerns.
