Review: Seems to be doing something! - I've only had this installed for a few days, but it has made a noticeable difference. From the moment I unboxed it, my cat sensed it and within a mere few seconds of plugging it in, my cat went up to the diffuser to sniff it. So far I've noticed she's been in the room even more often which I didn't think could be possible as she's already in here the majority of the time and also she's been much more approaching to us in a way that is very affectionate. She can be affectionate at times but the consistency of this level of affection over the past few days leads me to believe it's helping a lot. I can see in her eyes they seem more happy and even lubricated. I wouldn't go as far as to say it's like magic when it comes to behaviour but you certainly should notice a difference. Unfortunately it hasn't really helped too much with her overgrooming or her relationship with our other cat but I've noticed when she does overgroom these past few days it has been a visible less amount of fur that's bitten off. She still has scratching tendencies though - for now. It was super easy to install. It doesn't smell, the diffuser is a bit warm or otherwise slightly hot from being plugged in 24/7 but so far hasn't smoked and is not boiling or as hot as some reviews make it out to be - the worst I'd compare it to is a laptop charger brick but those vary. I also noticed if I touch the diffuser briefly and go to pet my cat, she can sort of smell the pheromone on my hand or fingers and gets very happy. 5 star review simply because you can't put a price on the happiness of your cat, even if it doesn't quite nip the other things in the bud it definitely has them feeling a lot happier and expressing more affection.
Review: The important thing is, its WORKS! - As with any niche in the market, you pay the price for it. Feliway optimum diffuser does work, it gives your cats extra reassurance and fewer fights happen. I have 3 cats, I set this up in the lounge and they all sleep in there are night, they are happy most of the time, their playground and sometimes they do go out, but not too often through the daytime. No need to let your cat outside when you have these things running. But they are expensive because they only last one month at a time. You also pay for the brand name Feliway, and there are cheaper brands on the market now, that do as good a job as this one. I bought it because it was extra strength and we have a Bengal prowling outside, so it chills them out after fighting the wretched thing off, when they come indoors.

## Questions & Answers

**Q: Will this help my cat sleep at night**
A: We use Feliway, but also a good play with a dangle/wand toy, then a small meal or food treat will get them ready for sleep. Cats have a hunt/eat/sleep cycle that thou need to replicate. Just keep toys with cords away from your cat when unsupervised.

**Q: Does this fit the Feliway original plug-in?**
A: The Feliway Optimum Refill fits the Feliway Classic and Feliway Friends Diffuser and vice versa.

**Q: Does it stop your cat from scratching your carpet**
A: There are no guarantees with it but it certainly stopped my cat from using my bed as a litter tray.

**Q: Feliway, can you tell me what temperature your diffuser reaches please? Thank you**
A: It does get hot after a while but had mine on for a month with no problem.
Didn't work though.

### ⭐⭐⭐⭐ Helped Reduce Stress for Our Blended Cat Family
*by C***T on 9 November 2024*

I purchased the Feliway Optimum Diffuser while blending two households, bringing a total of four cats together. My goal was to help reduce aggressive behaviors, spraying, and general stress as the cats adapted to the new environment. Pros: • Noticeable improvement in cat behavior—less fighting and territorial actions • No detectable scent for humans, but it visibly calmed the cats • Effective for all four cats, making it a good general stress reliever Cons: • Cats did not become best friends, but they tolerated each other better • Range is limited, requiring one diffuser per level of the house, which adds up quickly • Monthly expense, as each diffuser lasts about a month • For more targeted stress relief, the spray version might be a better choice
