Elixir –
Pricey but effective. Keeps the cats calm and happy.
These things keep the cats happy and calm. This box has six refills and three diffusers, and honestly I only use them one at a time, but it lasts. All year, pretty much. The price seems to be continually climbing, but it’s still worth it.

Appears to be effective
Appears to work well in a rescue sanctuary environment. Definitely noticed a difference in behavior with the cats. Glass growling and fighting. Scentless to humans but apparently the cats can smell it. It does seem to have a calming effect.

Is it working?
Is the product calming the cats? Well, one is 18 and just wants to be left alone. Other is 3 and wants to play.Still aggressive but don’t dare stop using they might get worse.

Did it work?
We gave this Cat Calming Pheromone dispenser a try on an agitated cat that was being fostered. Did it work or make any difference? I didn’t notice any change, and followed the instructions to the letter. Will it work for you? Who knows. It is very difficult to measure the effectiveness. If you can afford it, might as well try it. For someone short on cash, I would not recommend it. It was easy to set up but it is important to follow the directions – re: placement, etc.

Not sure recieved true product
I got a new-to-me 11 yr old kitty, her prior Grandmama also gifted me with the can of spray by Comfort Zone. That spray truly helped kitty adjust more calmly into her new home.Each and every time I sprayed it she would calm down and purr and you could see the content in her eyes. And I could smell it every single time. Unfortunately, it wears off within 4 or 5 hours; and it makes the situation rebound where she’s nervous and skittish again.I knew I needed something longer term and the diffuser sounded like an awesome idea. Sold by Fanny Gifts. Ordered 11.04.22These 2 diffusers were placed approx 20 ft apart, one in the small bedroom and one down the hall.1) These diffusers barely have a scent like the spray, allllmost nothing, to be exact. I SHOULD smell something similar to the single can spray, even slightly. Nope.2) Neither cat reacts to them, notices, or investigates.3) It has been almost 2 weeks, and no change in their behaviour. The hissing aggression continues, until I use the individual spray.4) I bought a different brand of individual spray, it has far less scent; but, still works far better than these dual diffusers. …Lasts far less than 4-5 hours to make it through the night, though.5) Purchased two other high priced name brand diffusers, and in 24 hours they are far more calm. I sense they will Finally learn to live together. (Will update soon.)Ultimately, I do not understand how the two diffusers aren’t the same scent or behavior reaction as the single can spray I received. The only thing I can surmise is that maybe it’s watered down or old or some other something something I don’t know.I’m still learning about using pheromones, but, the partially used can of spray of this same name brand Truly Does work. Somehow, the diffusers do not.Edited: 12.01.22. One of the units blew my outlet reset. The unit looks fine, unit was warm…. but somehow, it popped.The 2nd unit is still trying, but, ultimately….it is not helping the cats coexist. Will remove and toss for fire safety.

Works great
I didn’t believe it would work but it is!!!!! We moved and where we live now is on a very busy intersection so my cats can no longer go outside so they started fighting all the time and the one took to peeing on the floor by the litter box and on any clothes left out. So my friend suggested me to get this and I cleaned the floor with an enzyme cleaner as per the directions and plugged in the diffusers on opposite ends of the house. They have no sound are small and discrete. I don’t smell anything funny and they look like any other diffuser. Would highly suggest and I will be buying refills! I have no more cat pee and the fighting is almost non existent!

Excellent product that benefits your pets
We’ve been using the comfort zone value kits for several years and find them to be cost-effective and truly beneficial to our felines. Without question there is a calming effect that truly works well!

Leaks from the bottom of the diffuser
After around 3 months of use, I recently noticed that the oil is leaking out of the bottom of the diffuser. Sometimes we pull it to use the outlet it is used in, and now the unit leaves a small oily puddle wherever we set it down. Now I will have to find another one elsewhere, as we can’t get by without a diffuser for our male cat.

NO SIRVE. Lo compré para calmar a uno de los gatos (atacaba al otro), lleva más de un mes y se puso PEOR de agresivo. Según las descripciones, en una semana empiezan a verse resultados. Al menos para mí, fue una MENTIRA, en MI caso, NO FUNCIONÓ.

This product was designed for the US and Canada where the input voltage should be 120v, while our electricity in the UAE is 220v so when I plugged it in the diffuser started melting down, you will need a step-down voltage converter to be able to use it in this region.

This is an amazing product that really works. We have a female cat in our household. Recently, we had our family visit us. They brought with them 2 male cats and a Golden retriever. Prior to their visit, we purchased Comfort Zone Multi-Cat defuser. Three days prior to the visit, we plugged the two defusers in our living room and in the upstairs area. As soon as the new pets arrived, they acted very happily. The two cats were running around the entire house freely and did not display any fear or anxiety. They were rubbing themselves on the surfaces and were happy with us petting them. They were even asking for belly rubs. One of the cats is usually very skittish and runs away and hides a lot but when he arrived here, he was a totally different cat. Even his owner said, wow, he must really be reacting to the pheromones.Our female cat was a bit scared of the two new cats and a big dog, but after two full days of avoiding them, she finally relaxed. Now she plays with the two cats and hangs around the dog with no problems. We made sure that if it ever looked like the cats might get into a bit of a conflict, that we would separate them and give them some time to chill. We are very impressed with this product. I can imagine that it would be hard adding just one extra cat into the household. With this product, we were able to add two cats and a big dog without any problems. Thank you so much for such a miracle!
