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.
  • FELIWAY CLASSIC Starter Kit includes one diffuser head that lasts up to 6 months and one vial that lasts up to 30 days, covering an area up to 700 sq. ft.
  • 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.

    Our neutered male cat did not appreciate when we adopted my mother-in-law's neutered male last winter. We used a very gradual introduction and, except for a couple of hiccups, it seemed to be working Then for some reason, our cat became aggressive and the new cat spent his days in hiding. Marking was a common problem, too!
    A friend suggested Feliway. What a change! Both cats sometimes choose to eat beside each other, they occasionally play AND there is no more marking! Thank you!

    Feliway is the way to go!

    We were having problems with our male cat who is 13 years old... he shares the run of the house with 2 teenagers and 2 dogs. Over the past few months he's become extremely anxious and has taken up hiding in the bedroom, which has brought on other behavioral problems. While we made some changes with where the dogs are allowed in the house, and it alleviated some of the problems, our cat has still been exhibiting some anxiousness. I haven't used Feliway in years. After reading about how to help our cat get through his anxiousness, we decided to bring back the Feliway. We now have a Feliway diffuser in every room of our home and we even purchased the Feliway spray to use on furniture and other areas that he has taken up using as a scratching post. After about 2 weeks, we can definitely say that things are 100% better. Our cat is no longer hiding and he even comes out and parades around the house in front of the dogs and the kids. The Feliway has certainly helped calm his nerves! I will most certainly be buying it again from Entirely Pets... they have the best prices around AND the shipment arrived promptly. The little sample cat snacks that came with our order were fabulous as well... the cat has fallen in love with the Kitty Crack, so we'll be adding that to our next order!

    Stopped my cats from marking and fighting
    March 21, 2016
    I have an older female and a young female. The young female was hissing a lot at the older cat, and the older cat was marking in the house A LOT. As soon as I installed a diffuser on each floor, everything improved. No more marking and the cats generally seem much more at ease with each other and in general. Highly recommended.

    I have 5 cats and 3 of them were born to feral parents. I have now made them my pets and this Feliway does help calm them and keeps them from urinating in areas other than the litter box. I learned of this product first from my vet. Then I learning I could buy it online at Entirely Pets for a bit less. I highly recommend this to anyone that might have a cat issue.

    worth the cost
    October 31, 2015
    Easy way to keep available for use-the liquid seems to be helping to lessen bad behaviors in most of my cats--and the diffuser was what made the difference-just the spray was not quite enough, but diffuser saw some real improvement in behavior. I am pleased and relieved.

    Our female cat was forever fighting with her brother and he was living under a bed, so afraid of her. The product seemed to calm her down and relieve the stress of the male cat. The fighting upset me terribly and I was at the end of my rope as to what to do...the diffuser worked.

    We have three cats. We found a cute little kitten who we adopted. The older cats were not happy about their new baby sister. Then we purchased the Feliway Electric Diffuser. It takes a few days, but they have all calmed down. Even our grumpiest cat is happy! They all get along and now play together. Thank you Feliway!

    I have a10 year Himalayan neutered male cat.
    When I started bringing feral kittens home to tame and find family's for them he started peeing in the floor, on my shoes and on all the rugs. He has been doing this for 4 years it has been a nightmare I was at the breaking point when I heard about Feliway, used it ONE month and he stopped his bad habits and I would recommend this product to everyone, it truly works

    I have used this product in the past and since I will be having repair work done inside my home, I wanted my two cats to be more content through out the construction period. Hopefully Feliway will do the trick.

    Worth the money
    March 31, 2015
    We have been using Feliway Diffusers off and on for quite a while. Recently two new cats moved into the neighborhood. The territorial marking began! We brought out the diffusers, but they didn't seem effective. I noticed there was a lot of old brown gunk on them and remembered it is recommended to replace the diffusers. We ordered new diffusers and some needed refills. What a relief! The marking has ended.

    March 11, 2015
    I have a 5 year old cat that started pooping and peeing outside of the litter box after I had new flooring installed. I took him to the vet and the vet said he was suffering from anxiety. The cat was put on Prozac and trying to get a pill down him on a daily basis was torturous. It did not work. I was going crazy cleaning up the messes. I tried the Feliway diffuser product and put in three diffusers in the areas where he was generally pooping. It worked like magic and he hasn't had an accident since installing the diffusers. I am overjoyed.

    Works well
    February 22, 2015
    I have a newly rescued kitty - a patched Tabby. As soon as I plugged in the 3 diffusers I noticed a difference. It still has not resolved the war between the new torti and a calico, but for the 7 others it certainly helped. I still use the spray when things get really serious.

    Have a new rescued kitten and my 2 year old rescue does NOT like her one bit!!!! My third loves everyone. The diffusers have helped calm everyone down a little. Hopefully in time they will learn to get along. This isn't my first rodeo so I know it will take several months. This will keep it down to a low roar in the meantime.

    Calms Cats
    January 17, 2015
    We have used Feliway for 7 years along with Pheromone collars to calm three of our cats. One is aggressive, one is a scaredy cat and pulls out her hair and one is a pariah cat. It works for all three cats and we don't have to keep track of when to replace them. The cats' behaviors return and we know the month is up. Both the Feliway and the Pheomoine collars are HIGHLY recommended

    Not so hot!!
    September 13, 2014
    I bought four Feliway Diffusers on recommendation of my vet to calm my cats down. One cat redirected his aggression on his brother after seeing a stray cat outside his window and my vet thought this would help calm them down. I have not seen any change in either cat so now having to rehome one of them. However I did hear from a vet staff that this worked for her in similar situation so don't give up on it.

    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.

    My almost-17 yr.old Gent with declining kidney function and consequential acceleration of thyroid is greatly calmed with the use of the Feliway Electric Diffuser. I have one in the dining room where he naps much of the time and one in the upstairs hallway that I believe is sensed by both him and my 12/26/13 "adoptee", a 7- or 8-ish female when they're in that part of the house.

    I believe Feliway really helped!
    July 3, 2014
    Two of my ten cats had to have surgery recently plus another cat suddenly got very sick and the vet had to euthanize her. This caused stress to all of the cats but I think the Feliway deffuser helped calm them and aided in the recovery of the two that had surgery. Also, when the two that had surgery had to return to the vets for follow up visits I sprayed their carriers with Feliway and I think this also helped keep them calm for the trip and visit.
    Thank you Feliway and Entirely Pets!

    I haven't been using this product long enough to be sure that it will work efficiently. So far, my cat has had one relapse. That was 10+ days ago. She's behaving better than before I used Feliway, but I want to wait a while longer to really believe that it is working as planned.

    This really seems to help with my cat's stress peeing. Lasts about a month, so a little pricey. Worth it though.
