Feliway Diffuser — A Quick Look

Feliway comes in spray or diffuser form and it reduces your cat’s stress levels by releasing pheromones in the air. The product emulates the natural pheromones that a mother cat releases to calm her kittens, so it actually feels like a warm hug. It is very useful in almost all situations when your cat is stressed out and might display erratic behavior like hiding, scratching, meowing, biting, urine spraying, or fighting your other cats. Feliway actively reduces this type of behavioral issues by reducing general stress levels and calming the cat down in a natural way.  

Are Feliway Diffusers Veterinary Recommended?

According to the Feliway official website, there are numerous studies and clinical trials that have proven the efficacy of their product. The best possible proof is that you’ll find Feliway diffusers used in veterinary clinics.

The next time you take your cat to the vet, look around the exam room. There’s a high chance you’ll see a Feliway for cats diffuser plugged in. Why? Because veterinarian visits are some of the major stressful situations in any cat’s life and your vet knows it. By helping the cat be less stressed when it comes in for its examination, the entire experience is better for both the cat and the vet.

When animals are very stressed, examining them is very difficult because they can be aggressive and because the stress might affect some of the parameters that the vet wants to examine such as heart rate and body temperature, both of which increase when the animal is stressed.

Moreover, for some specialized examinations, such as cardiology examinations, eliminating the stress effect is extremely important. In fact, helping the cat to calm down is the first step of a vet cardio examination.


Still wondering how Feliway works and how cats respond to it? Then take a look as we go through the most commonly asked questions about the product.

Can Feliway be harmful to cats?

No, Feliway is not harmful to cats because it mimics a natural pheromone that cats produce. This will only have an effect on the cat’s behavior, and not on their human companions or other animals you might have. What you may notice as the diffuser is plugged in is that the cat might be grooming more than usual or it might have an increased appetite.

Can Feliway cause aggression?

No, Feliway mimics a pheromone that mother cats produce to calm their kittens, which is universally calming for cats. Studies have shown that it has great results in reducing aggression in cats, even in multi-cat households.

Does Feliway make cats sleepy?

While Feliway has a calming effect on cats, it is not a sedative. The active ingredient in it is a synthetic pheromone, which is different from sedative medication that might make the cat go to sleep. The diffuser will make the cat calm down without making it sleepy.

Does Feliway have side effects?

Since Feliway uses a synthetic pheromone that mimics a natural one that mother cats release to calm their kittens down, it does not have side effects on cats. Some cats may groom themselves more than usual or they might be more interested in food, but this type of behavior can be linked to kitten behavior. When kittens are with their mother, they feed and then they groom themselves.

As for side effects that humans might display, these are very rare. Some people have reported feeling nauseous or having a headache after they’ve spent a long time in a room where a Feliway diffuser is plugged in.

How quickly does Feliway work?

Considering that the Feliway diffuser has to spread the synthetic pheromone in the entire room to be efficient, it can take up to 24 hours to reach the right levels. Once this happens, the effects of the pheromone are almost immediate on the cat. If you intend to use Feliway for a situation that you anticipate will be stressful for your cat, it might be a good idea to plug in the diffuser two or three days prior to this, if possible, to make sure that the diffuser has spread a sufficient quantity of pheromones in the room. If you’re dealing with an extended stressful situation, such as bringing home a new baby or a new cat, or having one member of the family relocate, then you can leave the Feliway diffuser plugged in. If needed, keep in mind that you can simply refill it.

Can Feliway make cats worse?

No, it can’t. The natural pheromone that Feliway mimics has a calming effect that reduces anxiety levels in all cats. No study or clinical trial has found cats to respond with increased aggression or anxiety by being exposed to the synthetic pheromone, so rest assured that your cat will not get worse.

How does Feliway make cats feel?

Feliway reduces anxiety levels in cats and makes them feel calm, which leads to a notable improvement in the cat’s behavior. They won’t be sleepy like they would after being administered a sedative. They won’t be overly loving or hyperexcited like they would after getting catnip. They will simply calm down, purr lightly, and likely groom themselves.

    I have a split level house with 3 fur babies. Our newest kitty is aggressive with the oldest, most laid back (10 yo., weighs 5 lbs) with issues. Where would be the best place to put the diffuser?

    1. I think it talks about square footage – you might read the package or details online to see what they suggest per how many square feet…and then you’ll know where to put however many.

  2. Anne Kilpatrick says:

    A Feliway diffuser brought this baby close to death, he is still not out of the woods. Feliway was contacted and they denied any complaints even though the doctors said the burns were caused by the chemicals in the diffuser. He and his Mom are desperate for help. Read the story and you will see how dangerous this product can be.

    I just got the Feliway diffuser for multi-cat households on the recommendation of my vet. I was pretty skeptical, but I have to say now that I’m glad I took the suggestion. One of my babies was a shelter kitten and quite obviously traumatized from what happened to her either before or during her shelter stay. She’s always had an issue with anxiety and it just gets worse with age. I took her in to discuss anti-anxiety meds or antidepressants as a solution, but the vet encouraged me to try this first. Nothing happened for the first few days, but by the end of the week she was amazingly affectionate as were all of my babies. She was even affectionate with the new kitten who had previously contributed to her anxiety. Definitely worth the expense.

    1. Cool – glad it worked for you – thanks for sharing your experience.

  4. Wonderful product review post & video, Jenny!!! LURVE me some Ash-man in a video!!! Amy’s voice over at the end was hilarious, too!!! 🙂 <3

    I completely understand how difficult it is to do a product review video on this type of product as the results can be very subjective. I'm happy to hear that your vet likes it so much and believes it really helps. I would imagine with multi-cat households anything to keep the "Pissypants" behavior at a minimum is SUPER PAWESOME!!! (Lurve the term "Pissypants" SO MUCH!!! lol) 🙂 <3

    I have no experience with this product but do have the PetRemedy product (which I won in a previous super pawesome Floppycats Giveaway a few years ago). Unfortunately, we didn't find PetRemedy effective with calming Miss PSB for situations like nail trimming and butt fur trimming. But that was then. I should try it again with her. 🙂 <3

    Big hugs & lots of love!!

    Patti & Miss Pink Sugarbelle 🙂 <3

    1. I do think Pet Remedy helped us last year at Thanksgiving – cats and humans….maybe Feliway would be better for Ms. Pink Sugarbelle.

    Yes, yes, yes! It absolutely works! Best product for calming anxious kitties! Cant be without them upstairs and downstairs. Can always tell when it runs out because our Maine Coon Mari, will begin to act aggressive. Just used it with our ferals when bringing them inside and it helped them tremendously!♥️

    1. Thanks for sharing, Teresa. When we reviewed the Pet Remedy – I found that it calmed the dog, the cats and the humans =). This one can be hit or miss with us – but I think it’s because I don’t have it out long mom tried it to prevent peeing on furniture and didn’t go so well…the thing that has helped that is Parker. His presence has made outside kitties not come around the house – so Murphy feels more secure now with only his smells in the house.

      1. Teresa Reid says:

        That’s great Parker helped and makes the kitties feel secure!
