Is there a difference between this and the normal feliway? Does it work for multiple cats?
Answer by ChewyNov 01, 2021
FELIWAY Optimum can reduce scratching, urine spraying, tension and conflicts between cats, fears, and reactions to changes. It is designed for use with single cats or in a multi-cat household.

What is the difference between the optimum and the multi cat and classic?
Answer by ChewyNov 13, 2021
Feliway Optimum provides a message of enhanced serenity to cats. This holistic message helps all cats feel more comfortable and secure in their home by providing reassurance as well as harmony between cats living together. Feliway Classic provides “happy messages” to cats and makes them feel comfortable and secure at home. Feliway MultiCat provides “harmony messages” to cats to help restore harmony between cats living together.

So the diffuser itself is different for the Optimum than the Original and Multicat? How and why?
Answer by ChewyJan 11, 2022
The diffusers were recently updated to include a light. If your diffuser's warming plate (plate covered by the slats) is beige, the diffuser will not have a light. If your diffuser has a black warming plate and a silver ring around the opening for the wick, the diffuser will have a light. The refill instructions do not indicate which diffuser will have a light. As outlined above, depending on your diffuser style there may or may not be a light. The refill will not add a light to your current diffuser if not equipped with one. Diffusers should be replaced every 6 months or 6 refills, whichever comes first.

Does this contain the diffuser and scent to start with or do I need to buy something else?
Answer by ChewyOct 15, 2021
This starter kit includes 1 diffuser head and 1 vial. The FELIWAY Optimum Diffuser is only compatible with a FELIWAY Optimum Refill. Replace the vial once a month and the diffuser every 6 months.

A very useful tool to improve cat behavior

This product is very helpful, as my family adjusts to a very busy, active and somewhat aggressive new cat. I initially tried this for 30 days in the second month of owning this cat, and her behavior began to improve. We hoped she was beginning to feel more safe. She was calmer, less aggression and we thought we were over the worst. 10 days without the calming pheromone influence and bad kitty was back! I reordered and received my product in 2 days and once again she is calmer, still very playful, but it takes the edge off. We hope she'll eventually settle and this pricey product won't be necessary forever, but it helps! My aging mom, (the real cat lover in the house) and my little chihuahua mix are safer with a calmer kitty. And with the structure, active play, and clear boundaries we've set we hope she'll be a happy member of our family for years to come.

A skeptic but now a believer

My two new cats started having wrestling sessions around 2 AM each day... we share the master bedroom in my apartment. I could not sleep. I had heard of Feliway for ages but never tried it. Now I am a convert. Instead of 30-40 minutes of wrestling each night, the cats are down to perhaps one five-minute session a week.

This stuff really works!

One of our 2 cats, we don't know which one, because no one is talking, peed on my brand new (expensive!) sofa. Someone had also been peeing outside the box fairly regularly. Bought the optimum diffuser with high hopes................plugged it in, and it worked! 2 days later and peace reigns... calm has been restored. We are all happy : )

We recently moved with our 3 cats and dog. I was concerned that the upheaval in the cats lives was going to cause our one male to continue to spray but even worse. I spayed the car and their carriers with the Feliway spray for the 6 1/2 drive and plugged a diffuser in right away. They have settled in well to their new environment and I haven't seen or smelled any signs of spraying. It has been 2 1/2 months. I live this product.

Happy Captain Jack

I totally recommend pet owners to get this. We recently had got a new cat who we call CJ. He's a five-year-old black bombay who was given to us because his prior owner could not keep him due to her work and consistent travels. Since getting this feliway diffuser C J has become more comfortable in the house and with myself and my parents. It's a totally worth wild investment to get if you ever get a new cat.

Yay! for rescue kitties and Feliway

Thank you Feliway!!! I always rescue. My newest kitty was a captured stray and he had learned those typical outdoor kitty behaviors which included territory marking, even after being neutered by Animal Control. I haven't dealt with this issue for years now since I have had indoor only kitties. He is a sweet, loving guy and very gentle and sociable to me and my other male kitty in all other ways. But he was driven to spray and mark. Problem is now solved with Feliway and sooner than I could have hoped. We are a happier home.

Cats couldn’t care less

My 9 month old kitten wants to rough house with my 7 year old cat and she does NOT want to play with him like this so I was hoping this would get them to chill out. They couldn’t care less and mad 0 difference in their behavior. Wasted money

Try it! It worked for us!

My 8 month old kitten was visibly stressing out my 8 year old cat (hissing when he didn't want to be bothered and even urinating outside of box). I put one diffuser in the room with the litter boxes and one diffuser in the living area by their cat tree. It has been a month since starting and my 8 year old is back to himself! Playing, eating good, socializing more, and even going IN the box to pee now. Be sure to stick with it for the full month, it did take 2-3 weeks to see a change in their demeanor. Also, try not to plug in diffuser near heating vents.. it seems to go through the liquid quicker from the forced hot air blowing so close. I only got 20 days out of it, other diffuser (away from vent) lasted the full 30. Definitely worth a try! Just be patient with it!

WORKS! Reduce Stress + Urine Spraying

I absolutely love this product. I was recently out of town for a month and a half—my kitty was staying with a friend during this time. I was worried about stressing her out once she was back home. However, I plugged the diffuser in about 4 hours before bringing her home and it only took about 30 minutes before she settled right in. Prior to my month away, I’ve used this diffuser to reduce stress/over grooming and control urine spraying. We’ve had our fair share of environmental challenges in this house. It’s a large, old house and she’s used to a smaller apartment on a higher floor. So we’ve dealt with stray tom cats coming around the property and she has ovary remnant—causing tons of stress. This diffuser (paired with changing the location of her box and only allowing access to two rooms upstairs) has been a life safer to my sanity & our floors lol.

Please Get This, A Gamechanger!!!!

I was skeptical about whether this was actually going to do anything, and even after buying it, hesitated on whether or not to use it (due to some leaking concerns). After finally doing it, I wish I would have done it sooner! My cat is a bit of a scaredy-cat, has been bullied previously a lot, and even since now living as a solo cat, has had some litterbox issues due to stress (as the vet has said). She was finishing her stool outside the box at least once or twice a week, and even rushing out the box. Three separate vets had recommended using Feliway, and I'm so glad I finally did. Since plugging this in, this has stopped COMPLETELY! She comes out of the litter box way more calm too. I also have not had any issue with the diffuser leaking either. And even if it had leaked, it's not a big deal at all. I could not recommend this enough! I bet this would have helped the bullying situation as well. A tip if you have an air purifier in your home -- as far as I was reading, it should not be a big deal to have the diffuser near the air purifier, but they recommend keeping the diffuser ~10 ft away from it to be sure. I've just kept it across the room and that seems to be working well!
