We won't go a week without this stuff from now on.
We have a cat that has some anxiety issues which unfortunately manifest in the form of fights and marking. These absolutely changed his demeanor as well as the relationships between all of our cats. They are so much more docile, affectionate and calm when we have them installed. It's truly a live saver. Reduces indoor marking as well. Easy to use and replace, no odor, you wouldn't know they were there. Very effective.

Calmed our cat down within weeks, did not make the cat docile.
The COMFORT ZONE Multi Cat Calming Diffuser Refill, 6 Pack – Cat Calming Pheromone Refill does exactly what they say it will do. Since we have been using the Comfort Zone calming we have noticed a great improvement in our cats temperament. Prior to getting the Comfort Aon calming we had a big problem with our cat scratching and biting us. Within weeks of installing the Comfort Zone diffusers the cats attitude changed, slowly we saw less biting, and less scratching. Within two months the cat had completely stopped the issues. The Comfort Zone diffusers are not making the cat lethargic or docile, he still runs around, jumps on furniture and couches, but just is a lot more pleasant cat to have in the house. He even now plays with our occasional Great Dane visitor, no claws but smacks the much larger visitor make sure the Great Dane knows he is the boss. We have a long house so we have one at each end of the house, one by his food, and another by his second litter tray.

Seems to work for my Wild Ones, can be a little messy but Worth it if it works for your Cats.
I am careful with these, and have begun to wear gloves as they can leak and get on you when installing. Comfort Zone seems to calm down the crazier of my fully hand raised furbabies, so I've been using it for awhile... they are getting to be full adults now, more mature, and I'm hoping to wean them off of it sometime in the future. Cats are crazy. Compare all the options for bases and refills and look for the best deals as some seemed to be more affordable than others. Subscribe and save has worked well for me here.

This is the greatest product I have found for my cat's
I have two cats, Olive, Trouble Under Foot, and believe me he is. Oli is part Russian blue and part Schizophrenic. Sophie Grace is part Main Coon and Petrified Sweetheart. Sophie is still afraid of us after 5 years. It breaks my heart to think of what happened to her before her 8 weeks when we got her. Sophie has tolerated Oliver, but they are not best friends. Oli would like to be an only cat and he does his best to get rid of Sophie, (it’s not going to happen). He takes Sophie’s blanket from their room and hauls it to the laundry or to the trash in the kitchen, he eats her food and will push her out of the way if she is sitting in her favorite spot in the window. They got along reasonably well until Oli had to have some teeth pulled. He was so angry when he came home, he took it out on Sophie. I had to separate them for a few days, and I was in a panic mode trying to figure out what I could do to calm him down. The Vet told me to get a Pheromone product and that should help. On-line I found several products that were very insightful and after much review I chose Comfort Zone. This product is amazing, it calmed Oli down and he was no longer screaming every time he saw Sophie and it helped her nervous little body to calm down. At first, I purchased one Comfort Zone to give it a try and put it in my office. I noticed that both cats were in the same room and not fighting. I couldn’t wait to order 6 more. I have them upstairs and downstairs and two in their room and we are back to a calm house. Well, Oli would still like me to get rid of Sophie, he is still very jealous of her and resents me giving her attention, however, Oli is no longer dragging her blanket out of their room. I HIGHLY RECOMMEND COMFORT ZONE. It has saved our peaceful home from a constant battle. Now, both cats are sitting in the window together! I am sorry I didn’t find Comfort Zone 5 years ago This product is a game changer.

A must for the kitties
My cats respond very well with these! They last a true 30 days which is nice. Scent is incredibly low. Definitely pet friendly. Highly effective. Not too heavy for standard outlets.

Worth the money
It works. I live in a rat and mouse infested apartment building. I feel like I need this stuff just as much as my cat! He was terrified and I believe he was attacked at one point several months ago. I cannot afford to move anywhere. I can afford this though. I wish that I could afford to buy enough so that every single electric outlet could have one.

Came empty, leaked through the box onto all of my other items.

Two male cats
Last June, due to unforeseen circumstances, I brought home my work cat and had an issue with my home cat bullying my work cat. I bought these upon my vet's recommendation in August, and it has been so much more peaceful in the house. My husband, who is very touchy with smells, hasn't noticed them at all. The boys are getting along well. I have these downstairs (basement) in my bedroom and the main hallway for them. They are to the point that they sleep upstairs on the couch together, and I do not have the diffuse there, but its near the stairs. I have a 3-month subscription for these diffusers.

Buen precio por dos botellitas
Entre estas y las feliway, noto que estas funcionan mejor con mis tres gatos. Las recomiendo, aunque pareciera que no hay efecto cuando las tengo, tan pronto se acaban y no tengo más es muy notorio el cambio con uno de mis gatos que se pone muy ansioso y territorial.

Duraron menos de 10 días, no hicieron algún cambio en mis gatos
Fue un desperdicio de dinero, esperaba que duraran al menos 2 o 3 meses, puse 3 en simultaneo por toda la casa y no cambió en absoluto el estado de animo de mis gatos, por demás... ni siquiera llegaron a los 10 días. Simplemente fue dinero tirado a la basura...
