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.

  • 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.

Changed my cat's attitude
I've used Feliway for years to help my two cats, who hated each other, get along. I'm down to one cat now, and have moved him to a new home far far away from the old one. Recently he's been depressed, hanging out in a dark room, seldom coming out to hang out with us. I put the Feliway in the room he was hanging out in and one in the kitchen. After about 5 days he was back to his social self, full of love and craving attention. This stuff is great!

Great product
I have used this for years and it works. My 2 cats were born to a feral cat on my patio. I had some problems with non litter box use by one. This problem was 99% eliminated by using this product.

Review for 3 PACK FELIWAY CLASSIC Refill for Cats (144 mL)
I've used this with my stressed out Siamese kitty and it does help him. He is also on an oral medication prescribed for him by the veterinarian. Together these things do work. I'm very pleased.

A calmer kitty
This is the 1st time I've used the Diffuser, always used the spray in the past. I really like this product & it helped my female cat stay calm while we were gone on vacation. My vet also recommends this & uses it. Now I keep 1 plugged in on a regular basis. The bottle last about 6 weeks so the 3 refill deal really saved me some money.

Best Purchase for my pet
I used to get this all the time. It's getting so hard to obtain at a reasonable price now. It's the only thing that calms my cat and it's so hard to afford or find. So sad...

best buy for our cat
We have a very intelligent but high strung cat. We purchased the Feliway diffuser and refills and what a difference this has made in her behavior. The price at Entirely Pets is much less than the local pet store even with shipping added to the price!

Super Helpful Feliway Diffuser
The Feliway Diffusers help with new and stressed kitties. Daily use helps keep a calm household for new and established cats.

While preparing for a major house remodel, my vet recommended Feliway. I have two cats (a 6 year old and an 18 year old) that lived in separate rooms and I had to combine them in one room. My senior cat is a sweetheart; the 6 year old a bit agressive a times so I was worried. Three weeks into the project they are now peacefully co-existing and the 6 year old has become much more friendly to me. We still have a month to go and I will keep using the product after the remodel until everyone is used to the changes. I definitely believe Feliway has helped us all get through this.

Good product
I first purchased this through my vet and it is quite expensive but worked great! The second one I got through them as well didn't seem to have same affect so I bought from entirely pets. Not only did I save money, but it seems to be working for my kitties again! Helps with unruly behavior, scratching on things they shouldn't be, etc. Definitely worth the purchase, give it a try!

Love Feliway - for my skittish cat
Having 2 cats is such a joy except when one is a bit skittish. Feliway is great to alleviate his jumpiness and keeps him more calm and social. When the Feliway begins to get low, I can always tell by how my one cat reacts to noises, the other cat or even the dog. Replacing it = a calm and happy house!

Great for multiple cat homes
I found this product and now the three cats in the house seem calmer and less aggressive even if there are altercations over space and food. It helps quite a bit.

Feliway works!
I am currently using Feliway for my cats....I introduced a new cat to our home and they aren't getting along. I have been using the diffusers and my cat who runs from the new guy seems more confident. I am hopeful that they will eventually get along. Feliway has always worked in our house for stressful situations.

Would not be without it
I have 4 cats, and this really works. This product helps to reassure my timid cat, but it also helps my over aggressive cat to calm down. I also use the spray in my kitty carrier before trips to the vet.

Feliway plug ins
My cat started spraying while I was away. Apparently she doesn't like it when I travel anymore. Bad thing is.....she continued to do so once I got home! I tried the Feliway plug ins and they worked like a charm! She very quickly settled down and I have had no further spraying. I have since unplugged it as I have balance in the home again.....but you better believe that it will be plugged in a few days before I travel again to get her settled before I leave!

Really soothing!
Several of my cats had surgery several weeks ago and I purchased Feliway hoping to sooth them. I have to admit that I was not convinced that this would help but using the diffuser and also spraying their carriers and bedding really did seem to calm them! Thank you.
