Description

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 airflow 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.

FAQ

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.

This does calm the cats...
There is a difference from when the bottle is empty and I don't realize it...Our cats are not "cured" but, we do see the nervous behaviors much less.
They are nervous that our son's sweet but, cat chasing dog is going to unexpectedly show up....
Sadly, thhe sweet dog doesn't get to come any more.

Best thing I did for my 14 year old cat
My 14 year old cat was very anxious. After taking her to the vet and having tests done and nothing was out of kilter, I was so sad to see her like this. A coworker told me about the Feliway diffuser. So I purchased one and in a couple days she had calmed down. I have one plugged in all the time now and I can tell when I run out without even looking because of her actions. It is amazing! I would recommend it to anyone!

Stopped Male Spraying
After introducing a 3rd neutered male cat into my home one of the other neutered males began spraying his favorite throw pillows in the living room. I ordered one unit of Feliway Diffuser and plugged it into a socket near the couch. The spraying stopped immediately. I forgot about the issue until 10 weeks later, when a spraying incident occurred. I am here today to reorder!

Great value and fast shipping on a product that has worked so positively for a very shy, reclusive rescue kitty.

feliway diffuser great product
The feliway diffuser is the only product that truly calms my cat. This is one nervous cat, doorbells, water from hoses and all loud noises send my boy hiding. My cat is much calmer and doesn't need to hide anymore. That makes me happy! The price of Feliway at Entirely Pets is a good deal. It arrives on time with no problems. Excellent product and good price. Highly recommend to anyone with nervous cat(s).

Review for FELIWAY CLASSIC Refill for Cats (48 mL)
Feliway seems to work.
It's by no means a cure-all or miracle, but over past few years when stress was high among my cats, it seemed to help a couple of them.
I do believe it is worth a try to reduce stress in cats.

Peace for Gabbie
Feliway helps my cat Gabbie live a much calmer life than she would otherwise have. Without Feliway, when she is anxious she darts here and there and yelps out in pain. Feliway restores her peace.

Feliway Diffuser
We love the Feliway diffuser/plug-ins! Our vet recommended for our multi-cat household during the process of moving. We have one 'sensitive' kitty, and the pheromones help the stress levels. It benefits all 3 cats. Our vet recommended a second diffuser for our new home, and get it going there while keeping one in the old home until the move is complete. So far this has helped their anxiety levels and I hope it helps them adjust to new home easier.

trial and error-I think it helps!
AM not sure the Felway is as effective for each cat--but it definitely has helped some of my menagerie to behave better-I had scratching post being made out of a doorway by one cat (we moved here in Aug 2015)--that seems to have stopped though it took several applications of spray--another guy was spraying on counter-I put a diffuser there and that seems to have ceased completely. I am convinced it is at least effective for some of my 5 cats !! so will continue to use.

Feliway is great
I have used this for years and have always been glad to know about it. My neighbor and I have been working with a feral cat colony on our property and have had to relocate them to a farm. As we trap them, my neighbor keeps them in several pens in her living room for a week or so until the new caretaker picks them up. We use a diffuser with the Feliway refill and the cats are very calm and mellow by the time they leave. My neighbor is a Feliway believer now!

A must buy!
This helps both my babies while my husband and I take trips out of town. It seems to mellow them out so they are not stressed out. I highly suggest this for others!

Life saver
I was totally skeptical about this product, but we took in a young female cat who was peeing on the furniture and we were about at our wit's end, so willing to try anything.

This did not stop the behavior immediately as some have experienced, it took 7 days. But since then not one incident! I would definitely recommend it to anyone who has a cat that is marking or spraying.

Does what it says!
After seven years living together peacefully and with no problems, my 10 year old female cat decided all of a sudden she no longer liked the 7 year old male and was attacking him. I was distraught. She was checked by a vet for any underlying medical problem and was fine. I had used Feliway when the male was first brought home to smooth the way, and it saved me again. I have it in the two rooms they spend the most amount of time in and it really works. It does tend to need replenished more often than what is indicated, but is still well worth it for a calm household

Fantastic Product
I ordered Feliway prior to adopting my 2 rescue cats. Both are 9 years old and one of them is blind. I wanted to help reduce the stress as much as possible. I plugged in 2 days prior to bringing them home. The blind guy only took 24 hours to adjust and start interacting with me. The other kitty was comfortable instantly. I plan to order at least 1 more refill to keep us all happy!

Best investment ever.
I recently adopted two 9 year old cats. Charley is blind and I was worried about him adapting to new surroundings. I ordered Feliway and plugged in 48 hours before I brought him home. It has been 1 wk and he has not had any stress or out of litter box issues. I intend to order again.

Calming effect
My female cat was getting anxious around my older male. As a result, she was urinating on the carpet. I had her checked out medically and the vet said it was stress. The Feliway product has helped her calm down tremendously!

Much better than going to vet!
I use these all the time for my older cats. It calms them down and stops the "marking". I got 2 for the price of one that i would get at the vets office!

Feliway Diffuser Refill
I love this product. It calms my cat. He had been abandoned in a locked house that had a 30 day no entrance stuck to the door and no one knew he was in there. He had many behavioral issues when I adopted him. With the help of Feliway he's become calm and much more manageable. He trust's more.

Helping with Litter Box Issues
Feliway seems to be calming my cat, who began urinating outside the litter box following a UTI. I use one in the living room and one in my bedroom. Haven't caught him 'misbehaving' in weeks. It is a bit on the expensive side, and it doesn't last very long, so I was happy to find a good discount here for multiple refills.

It Works
This product seems to have a calming effect on my female cat. As for my male kitten I don't think it has any effect on him.

Like CatNip. My female loves but my kitten doesn't care. He is like "What is all the hoopla" about?

Feliway Diffuser
My vet recommended this product to help calm my cat when visitors came to the house. I think it has helped and Entirely Pets price was much less than if I had purchased it from my vet.

A Must Have
An ice-cream trucks music scared Gibbs so badly he flipped out and ran into furniture. He bruised his ribs, spine and had a huge hematoma on his chest. After this, when he heard it, he would run trying to find somewhere to hide. PTSD. I got the diffuser and immediately he was calmer. Now he sits and growls at the truck.
I will always have Feliway Diffuser refills and Feliway Spray on hand!

Great Purchase
The Feliway Diffuser helps keep my male cat calm. He is a breeding male and the Diffuser helps him control spraying.
