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

These behaviors are likely caused by fear and anxiety.

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

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

Use FELIWAY CLASSIC Starter Kit 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. Plug the diffuser in an electric socket with a minimum clear distance above the diffuser of 5 ft. (The vapor carrying the FELIWAY messages rises in a column of warm air above the diffuser). One diffuser covers up to 700 sq. ft. You may need to use more than one diffuser for a large or multi-floor home. Be sure to replace your diffuser every 6 months and refill vials every 4 weeks. 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.

  • 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.

    So good.

    Have a cat who has decided spraying is fun, got him on medication...still spraying =( So I thought I'd try Feliway. I ordered 2, 2 day shipping as I wanted them ASAP, it came in 5. Complained and got 2 mail apologies and discount on next order. Hopefully this stuff works, takes a month to know, and I will reorder and use discount.

    Inappropriate Urination Stopped!!
    February 1, 2017
    My favorite cat began peeing on our new carpet daily. We were devastated and it looked like the kitty would have to go. The vet recommended Feliway. We were skeptical, but after about 10 days of using the diffusers in the places she went the most, the behavior stopped! Now I've run out of refills, and she has started it up again. That's a cause and effect if I've ever seen one. If you have this problem, until the Feliway starts working, use Nature's Miracle Just for Cats Urine Destroyer. The carpet cleaner says that's the only thing that gets rid of cat urine.

    Cat stopped 'spraying'
    October 26, 2016
    After bringing my daughter's cat into my home for a temporary stay (daughter is on a military deployment), one of my own cats began spraying the throw pillows on "his" couch. After installing the Feliway diffuser, the spraying stopped immediately.

    Feliway diffuser and Refil
    August 12, 2016
    This is my second purchase of both the Feliway Diffuser and the Refils. I have noticed that my cats are calmer and their anxiety levels are lower.
    I have placed the Diffuser in two areas of my condo, and they are far enough apart that when the kitties walk past the area or if they are sleeping, the diffuser will work it's magic. I am very pleased with this product and will continue to purchase from Entirely Pets.

    Sleepless on Vancouver Island
    February 24, 2016
    Milo was keeping me awake/or waking me up with his meowing at night. At first this product seemed to help by calming him. After having used it for four months, it seems not to affect him anymore and I'm once again 'sleepless on Vancouver Island'!!
    I'll have to look for something else to keep him quiet at night.

    Better than ComfortZone Products
    January 28, 2016
    I tried ComfortZone for the 1st time in years of Feliway use & learned the hard way that Feliway is what WORKS! However, it evaporates much faster than the comfortzone. I've noticed the prices have skyrocketed, so it's become hard to afford it. It DOES keep my cat more calm.

    A lifesaver for my cat!
    November 22, 2015
    My dear cat has Rolling Back Syndrome (can't remember the "official" name), which causes her a lot of anxiety and painful episodes. Thanks to this diffuser, her uncomfortable moments are much less, which in turn lessens her stress and mine! The spray is also very helpful for use in her sleeping areas.

    Purchased on the advice of our vet. We have 3 indoor male cats that have been having turf wars for a few years. They have territory battles and ruined a sofa by marking with urine.
    We have been using the diffusers for not even a month and they do not fight any more and we have not had any urination outside the litter boxes.

    Review for FELIWAY CLASSIC Starter Kit for Cats (Diffuser and 48 ml vial)
    September 28, 2015
    Very useful but I would like the top to fit better.
    If I screw the top as far as it will go the refill is on its side, so I will not have the benefit of a full refill
    Also I find the product very expensive.
    I own two year old cat.

    Not for me
    July 6, 2015
    I bought this to help soothe both of my cats. One is shy and a little skittish and the other has an overgrooming/anxiety issue. I thought it would be a gentle calming thing to help them both. But I had an asthma type reaction to it. After it was plugged in for about an hour I noticed I was having breathing issues. It doesn't have a smell really, but my throat was burning and breathing became difficult. I unplugged it and my breathing gradually got better, returning to normal after a couple of hours. So I have no idea if it would help my cats or not. But I can't be around it.

    Our vet told us to purchase Feliway diffuser when our elderly cat started to have accidents and act anxious. The Feliway has worked wonders! I reccommend this product to everyone!

    Works but not the miracle I was seeking
    April 8, 2015
    I have two cats that suddenly started fighting with each other after being together for several years without incident. Feliway has worked wonders on my neutered male cat. He's so much calmer and no longer aggressive. Unfortunately, it hasn't been as effective on the female (spayed). She's less agitated when I have to lock them in separate rooms, but she still chases and attacks the male cat whenever she sees him.

    I hoped it would work , but not in our case, we have 2 female cats, one keeps bullying the new small one for 7 months now, I bought 2 diffusers, and a hand pump spray. I thought by now things would calm down. So thats about all I can say, it may work for some.

    I bought this on the recommendation of my veterinarian because my cat Thomas is always crying at night and waking us up. It made no difference whatsoever. The best and cheapest cure? Kick the cat out of the bedroom and close the door. Reinforcement is a spray of water from an empty bottle that I washed out and filled with tap water. Doesn't get any cheaper. And his reason for crying? He wants attention. Well, he gets it if he cries long enough, but it's not the the kind he's looking for. Don't worry- he gets plenty of loving during the day.

    For cats that have behavioral problem, and they do, Feliway is an excellent way to help combat those problems. Especially important is the peeing outside the litter box. It does take a minute to get started, but once it does, this behavior goes away. The cat is happier, I am happier and we are all happier. It is an excellent product; not a cure all, mind you, because I have only one cat. But, I can tell you, the product works and there is less stress in our household.

    Have used Feliway for years in a 4 cat household. Makes a big difference in keeping everyone happy. If I forget to replace them I get reminded by my one cat that likes to start skirmishes

    we drove for ten hrs. to Johns Hopkins Hospital in balt. Md. with our two 19 pounds kitty brothers.
    house kitties, had never been on a car ride other than to the vets. I sprayed and wiped down the whole truck and the crate. followed directions. then we spent over two months in a Marriott Residence Inn again i sprayed and wipe down the whole room. It worked they smelled every inch of that room. I can tell you for us it worked to keep them calm. It was a long time to be in such a small area. Ive also have it plugged up in my home and I sprayed my furniture. It worked for me.

    August 21, 2014
    Or I bet it would work on her. It's hard to tell whether it had a profound effect on my cat. She is a wild one, but perhaps in a smaller, well-ventilated room it would work best.

    Saved My Household!!
    August 18, 2014
    My vet recommended this product. I actually bought the calming collar in conjunction with the diffusers. Both are made by various manufacturers and the Comfort Zone & Feliway were out of stock at the store, so I ordered them online, and bought the Sentry brand in the store right away. Everything is working!! Everyone is hugs every day. I have 2 cats from the shelter. One was being very aggressive with his playfulness and the other was becoming tense and stressed out by the 1st cat's behavior. The more aggressive kitty had come from being a community cat (feral), so he was a little rough around the edges. He wanted to chase and wrestle the gentler kitty for hours and hours a day. He'd even follow the little fellow to the cat box and not let up the whole time he was trying to *go*. I had to put the aggressive kitty in "time-out" isolation sometimes. The poor little gentle kitty was on guard at all times. Immediately the collar calmed down the aggressive cat. Now he's Mr. LoveBug, and the diffusers seem to have had an immediate calming effect on the other gentler kitty. Now the kitty formerly known as Mr. Aggressive Cat plays more gently and grooms the gentler kitty. I've had the product for about 2 weeks now, and the behavior is getting better each day. They are both super mellow, and so much less hyper and tense. I can now sleep through the night and my bed isn't the scene of a wrestle-fest. They've both been sleeping calmly through the night. Keep in mind that each diffuser only works in a limited amount of space, so my condo has 2500 square feet and I have 6 of them throughout my unit. I'm a believer for now. And my plan is to keep the collar and diffuser for a few months and then wean them off of the product.

    I am planning to buy the feliway spray in addition to the diffuser. It says that it is ok to spray on furniture. Will it stain my furniture? It also says that the product is flammable. Over time; will that be a problem? we don't smoke etc. IS the product in the diffuser flammable too? thanks. Lynda
    1 Answer
    It will not stain your furniture with regular use and shouldn't create a problem if used over long periods of time; however, I would advise against drenching your furniture in the spray, as this might increase these risks. The liquid in the diffuser is similarly flammable- though the diffuser itself is made with non-flammable plastic. The best way to prevent fires is to ensure that the diffuser is properly plugged in when in use. The unit should also be plugged in away from furniture, curtains, blankets, or other flammable items.
