FELIWAY® Optimum 30 Day Cat Calming Refill for Pheromone Diffuser, 48ml - Helps Reduce Common Signs of Stress in Cats & Kittens, Enhanced Calming

My vet had recommend this to me to help keep my 2 cats calm. There was hissing and fighting. No more! It's a miracle! Truly a miracle. When I stopped for a couple of months the calm was gone. I bought it again and we all are living in peace. This product works! Try it. The Vet instructed me to purchase the "Optimum". Not the other one. It's not cheap. However, it's worth the money for your pets to kiss one another rather than hissing and chasing in anger while disrupting the whole house and upsetting themselves. Everyones happy. It starts to work immediately. No waiting to get results. Make sure to put it in a room where the aggressor kitty spends alot of time. Keep windows closed to get the maximum affect. It doesn't get them stoned. Just an overall calm. My other one who isn't aggressive is simply more relaxed from it. All good! My vet has 8 cats and they all live happy together due to the help of this product.

I have used this product several times now and it works so well!!!!! The most recent time we had gotten a 4-5 y/o cat that was given to us by my nephew. The cat was so scared to come out of hiding, and only in the cover of night would come out to eat and use the litter box. I ordered Feliway and within 3-5 days he was out and was our lap kitty! I can’t say enough about this product!!!!

I did the research in the differnt Feliway products and thought this would work best for my feline household needs. The Optimum seems to help with integration of two different cats and for winter season when they have to stay couped up in the houses more often than they like. Note: keep diffusers in rooms most often used by cats and away for windows/doors/fans for effectiveness. Unscented to humans.

We have three cats who are sometimes difficult with one another. We have one cat who is actually on Prozac because he has a high stress level. Our vet suggested these years ago and we have been using various brands over the years. Feliway is by far and above, the best! While they may cost a little more than competitors, they are worth every penny. I can actually tell when the diffusers are almost empty by the behavior of my particularly stressed ginger boy. If he has been acting out a little for a day or two, I always check the level of the diffuser. And sure enough, it’s time for a refill. Feliway diffusers certainly help keep the peace in our home. I can’t recommend them highly enough.

Our rescue cat had been returned twice for agression issues. We had no problems for three years then suddenly cat became extremely jealous of my husband and went from loving him to attacking him. Biting and breaking the skin. My daughter has used these infusers in her house for her 2 cats that can't stand one another. They are now able to cohabitate without fighting. I ordered the infuser and paid extra for immediate delivery. I plugged 2 of them in the rooms where we spend the most time. Honestly within an hour the cat was docile. We had two further incidents but husband is now the alpha male.

Works as stated when it's working but doesn't last even three weeks. The Optimal seems to evaporate much more quickly that the standard. At this higher price and shorter lifespan I am going back to the red label version.

We got these because our vet recommended them for our anxious cat- I believe they have helped a lot she’s still somewhat anxious but a lot better!

We've been a long time customer of Feliway. Whether it has been for a move or to help a stressed cat with improper elimination or acclimating kittens to a one cat household, I want so badly to say this works like magic. Tbh, I'm not sure. We had one plugged in the bathroom where one of our litterboxes was in an effort to help our cat do his business IN the appropriately sized, clean litterbox with unscented litter. It didn't help. If the cats could talk. Right? It's packaged right. The labeling says all of the right things. It's a high quality item. It doesn't leak. It's durable and of a generous size. Whether or not it has a calming effect? Only our cats can answer that.
