Is your cat peeing outside the litter box, scratching or hiding?

These behaviors are likely caused by fear and anxiety.

FELIWAY CLASSIC products are a clinically proven, drug-free solution to help alleviate many of the unwanted behaviors cat owners deal with.

FELIWAY CLASSIC refills provide “happy messages” to cats to make them feel calm and comfortable at home. By mimicking the natural feline reassuring messages (pheromones), FELIWAY CLASSIC helps cats happily adjust to pace of modern life.

Use FELIWAY CLASSIC refill vials along with the FELIWAY CLASSIC diffusers (sold seperately) if your cat shows signs of discomfort like peeing outside the litter box, hiding, or destructive scratching. Reduces urine spraying in 9/10 cats. Can see results within 7 days. You may also consider if you anticipate changes in your home (moving, renovation, redecorating, arrival of a new pet, arrival of a new family member).

Use the diffuser in the room where your cat spends the most time. FELIWAY CLASSIC Refill vials include one refill vial (diffuser head sold seperately). It is recommended to replace the refill every 4 weeks, even if a small amount of liquid remains in the vial (the vial will never be completely empty).

  • #1 brand used and recommended by veterinarians.
  • Clinically proven to work. Reduces urine spraying in 9/10 cats. Can see results within 7 days.
  • Drug-free solution that helps reduce signs of stress such as peeing outside the litter box, scratching and hiding.
  • CLASSIC Refill includes one vial per package that lasts up to 30 days (diffuser head sold seperately).
  • 100% satisfaction guarantee.

Useful Information

  • FELIWAY® Diffusers should be placed where the cat spends the most time. If you are considering this product for a cat peeing outside the box, you can also place the diffuser in the room where the cat is urine spraying most often.
  • FELIWAY® Diffuser should be used for at least 30 days. Most behaviors will show improvement within 7 days, including peeing outside the box and scratching furniture. Depending on the behavior, you may need to continue using the FELIWAY® Diffusers longer than 30 days.
  • When choosing a plug for the FELIWAY® Diffusers, make sure there is nothing above the outlet that will obstruct the airflow and diffusion of the pheromone. It should not be placed under a cabinet, behind a couch, or near an open window.
  • Refills will last up to 30 days but some variations may occur depending on air flow and ambient temperature within the room.
  • One diffuser will cover up to 700 sq ft in an open floor plan. The diffuser will not diffuse pheromone outside of any given room though. Given the size, floor plan, and where your cats spend the most time, you should consider getting more than one diffuser.
  • Diffuser heads should be replaced every 6 months.
  • Newly plugged in diffuser units may have a slight odor for the first 24 hours, but it may last up to 72 hours. Pheromone diffusers are made of self-extinguishing plastic and comply with the International Electro-technical commission (IEC), European (EN) and UL required standards.
  • HAZARDS TO ANIMALS: Keep out of reach of children.


    Do the Feliway diffuser refills fit other brands of diffuser systems? No. The Feliway refills should never be used with another brand of a diffuser device. The pheromone technology is designed to work at a certain temperature that is specific to Feliway diffusers.

    What pheromone is in Feliway? The pheromone released by Feliway is the synthetic copy of the natural comforting pheromone released from the mother cat's mammary area during the nursing period. This appeasing pheromone helps maintain the bond between the kittens and their mother and helps kittens feel safe and secure. The scientific team at Ceva has found that this pheromone can help reduce tension and conflict between cats in the home.

    Can I use Feliway with a young kitten? Yes. There is no minimum age for using Feliway pheromones. Kittens are able to perceive pheromones in the environment and respond accordingly.

    How long should I use Feliway? It depends on the nature and the extent of the reason you are using the product. The minimum recommended duration for most situations is 1 month. But some situations may benefit from permanent use.

    What type of behavior problems may not be helped by Feliway? Feliway has been tested in households where there is tension and conflict between cats. Feliway has not been tested for aggression toward the owner(s). In this situation, consulting your veterinarian or a behaviorist is strongly recommended.

    Should I unplug Feliway diffuser at night? No -- the diffuser should be plugged in continuously day and night. Frequent unplugging may prevent the diffuser from working properly. Efficacy was demonstrated in clinical trials with non-interrupted use of the diffuser allowing the cat to constantly perceive the pheromone’s signal. Furthermore, cats are awake and active even at nocturnal times.

    Can I use the diffuser in a room with air-conditioning? Yes, a diffuser can be used in a house (or a vet clinic) where there is an air-conditioner, provided that it is not plugged in near the air-conditioner, vents, cold air returns, or exhaust fans. Being near additional air-flow may accelerate the diffusion process and the refill vial may not last a full 30 days.

    How can I tell if my diffuser is turned on or working? When the diffuser is plugged into a working outlet, the diffuser head will be warm to the touch.

    Can I use the diffuser while leaving the windows open, particularly in the summer? Will that affect the efficacy? Usage with open windows or heavy air flow may result in diffusion at a faster rate. The product 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(s) spends most of its time.

    Review for 6 PACK FELIWAY CLASSIC Refill for Cats (288 mL)
    January 4, 2019
    So far it is working with my garage cats. They tend to not get along when the weather is colder and they have to stay inside. Feliway does seem to make a difference in how well they get along.

    I have three cats and all get along well but one cat is a worrier. The vet suggested Feliway some years ago and I continue to use it and she is more relaxed and happy.

    In a mixed (old & young) household of cats this keeps the spitting and hissing at a bare minimum. There is an immediate difference when the Feliway is gone.

    When I got my second rescue cat he started eliminating on the living room furniture (luckily it was covered). I closed off the room for a month, plugged in a Feliway diffuser, moved litter boxes around, and the problem was solved. My cats are now 7 and 8 and I still keep one plugged in at all times.

    Helps keep stress down.
    February 25, 2017
    We usually use Feliway refills about a month before vacations where we will be away from the cat for more than a few days. Then if needed, we replace them right before we leave. It seems to help alleviate the cat's stress levels while we are away.

    No More Accidents

    I was so pleased to discover the Feliway product. I was having problems with one of my cats urinating in the house and I was at my wits end. I asked my vet for recommendations and he suggested that I try Feliway. I ordered the Feliway Diffusers and placed them in several rooms. Since then, no more accidents. Love this product!!!

    We use this product in our rescue program. It really helps cats who are shy, ones who show aggression, and those who just need a little help adjusting to a new home.

    Four cats occupy this home. It is a busy environment, everyone wants their own space, and their own attention and reassurance.
    The Feliway product with the constant diffuser has had a surprisingly calming effect over all the cats. Things were good before Feliway, just far better now!

    It Really Works

    I have a very territorial cat who scents inside whenever he sees other cats in our yard EXCEPT when we have Feliway diffusers plugged in. No more scent...happy cat and happier cat family. Thanks Feliway!

    Feliway calms nervous cats
    August 10, 2016
    We brought a new cat into our home, much to the dismay of our existing kitty. Existing kitty was dominated by the newcomer and started exhibiting all kinds of anxiety-based behavior such as going outside the litter box, fighting, not sleeping in usual spots. We put Feliway in two rooms of the house where the cats usually hang out and over the course of a month, with a few other accommodations, the cats really calmed down. They're still not best friends, but they sleep together on the couch and the litter box issue was resolved
    , so I'm happy!

    Trying to help ease stress of moving
    July 26, 2016
    I have been using Feliway diffusers and spray for several years to ease stress with my two female cats, one of whom has a history of attacking her housemate when highly stressed. I have found the spray works well to reduce acute event-based stress. It's less clear what effect the diffuser has, but the cats at least seem somewhat calmer in its presence. My current purchase of 12 diffuser bottles will be used to pre-soak the interior of a new house we bought prior to the final move, in the hope it will provide a familiar scent and reduce general stress for "the girls" when they finally move in.

    great product

    My cat is very hyper - this is a necessary product in our home. You can always tell when the refill is just about finished - her anxiety rate goes up. Would definitely recommend this product.

    We have two lovely cats but they've come to us after being mistreated by previous owners.

    This is a great product that really helps the cats settle in the home and relax.

    Feliway Calms Our Cat
    May 7, 2016
    We've been using this product for the past 8 years and we do notice the difference. When we run out of the product, our cat Sidney gets a bit anxious.
    He is definitely a lot happier when the diffuser is on!

    Feliway Diffusers work!
    January 5, 2016
    Have three cats, grandmother cat, two grandsons. After having the boys for two years, one of them decided that Grandma didn't belong here. He would chase her unmercifully, if she was eating, he would go after her. It got to the point that if he came within 5 feet of her, she would hiss and growl. Decided to try Feliway. Started with the spray which worked well and reduced the cat stress greatly but I was tired of spraying morning, noon and night. That's when I got the diffusers. They have helped so much. Instead of having 10 cat attacks a day, we have less than 10 a month. I strongly recommend trying Feliway. I did and I'm glad I did. If I have to buy this the rest of our cats lives to keep peace in the house, I will.

    Finally a calm cat
    November 18, 2015
    I have two shelter cats one is fine the other problem child. He is aggressive, strong personality. he is fixed, and sprays. This product has ended that for us. Best stuff, and if we do not change monthly he becomes aggressive to his little sister, it is something that we have, all the time, plugged in. And we do check around for prices but it always seems Entirely Pets is best price, so we buy in 6 pack

    Feliway has worked well
    October 30, 2015
    It isn't foolproof, but Feliway has worked better than anything else we've tried (such as cortisone shots) to lower our cat's anxiety that causes her to eat the fur off of her front legs. We can tell when the diffuser bottles are about out when pink skin starts to show through again. I change the bottles (we use two), and within a couple days most of the pink has disappeared.

    Feliway is the real stuff
    October 22, 2015
    Been using this product for years. You can tell when product is used up, as the cats (4) will began to irritate each other more and more. Each bottle will last about 3 weeks in our case, and we always keep extra on hand.

    We are a multi-cat household (4) and can always tell when the Feliway is close to empty, because little spats and hissy fits break out. As soon as we replace the refill, peace and calm are restored.
    Wouldn't want to try and do without it, and neither would the two friends for whom I also order it!

    Feliway works, need I say more. No more 8 pounder verses almost 20 pounder competing over a favorite spot while us humans are trying to sleep.

    Great price!
    August 10, 2015
    I was really pleased to find this site to get the refills. I'd purchased two dispensers after getting a cat from a friend who died, and is very antisocial with other cats. The refills at the pet store were terribly expensive and these are a great price. Just wish I'd have gotten the discount for the auto delivery!

    Well not only am I using the Feliway spray, but I find that these Feliway Diffusers work well too. I'm sure I will continue to use this product as I have 5 cats that sometimes need to be calm.

    This product works
    June 16, 2015
    I have been using this product for a long time whenever I have had issues with my cats. It really makes a difference in their anxiety level. I recently ordered more refills only to be told that not only was it backordered but pulled by the manufacturer because their is a new formulation coming out. Meanwhile I am using my last two refills and will have to scramble to find more and also pay more until Entirely Pets stocks it. I was never notified about the product being discontinued until I was asked to rate the shipping. I also checked Feliway's website and there was no notification about a new formulation. I love the product and very disappointed that I could not get any more at this time.
