Review: Great for cats, works brilliantly - Review from a registered veterinary nurse. Highly recommend any pheromone diffusers, but this one seems to be the better one i have used. Used for my cat on bringing home our new baby. Had it on for at least 3 weeks prior to the new arrival. Worked well. She seemed happy and content and more at ease quicker. She also seemed to.settle onto a routine alot quicker with it. You noticed when it had run out as she would get a little more tense and hide in those early weeks of a newborn. Highly recommend.

## Questions & Answers

**Q: Does it fit same diffuser as normal feliway**
A: The Feliway Optimum refill will fit into the Feliway Classic or Feliway Friends Diffuser - and vice versa.

**Q: Does it actually last 30 days?**
A: No, absolutely not. The same is true for the Feliway Clasdic diffuser. I have replaced the unit, changed sockets but I am back on Amazon reordering just 20 days after plugging it in (I run it 24/7 as advised). Even Feliway say it may not last 30 days, so beware, as it's very expensive to replace every 20 days.

**Q: Do these have an expiry date?  If I wanted to buy a years worth at one time?**
A: I have some unopened Feliway Classic purchased around 6 months ago which have an expiry on them of 10/24
So I guess they last for two years

**Q: If ive been charged but cancelled my order will i get a refund?**
A: Yes you will choice of credit to your account which is the fastest way,  or back onto your tales 5 days

### ⭐⭐⭐⭐ We WERE sceptical at first but... DESPERATE
*by S***A on 23 June 2021*

In brief, our cat who is about 12 years old is extremely difficult. She always has been. She runs if there is a knock at the door, we can't pick her up for more than a few seconds, we have never been able to groom her for more than a few seconds at a time... no matter what we do we haven't been able to address her skittish ways. Also, with her getting older she has started acting weirder than normal and getting into very strange habits. So, in the first month of using this plugin, we didn't really see any difference until the end of the month. It was very slight. She seemed a little calmer so we thought we'd give it more time. We are now on our third plugin as we think it's working. It's still not easy applying her flea treatment but not as bad as previously. Even despite the slight benefit in behaviour we think it's worth it as she does seem calmer overall. In our opinion this is much cheaper than a prescription from the vet and definitely worth a try. And we suggest giving it at least two months. Also, we have a two bedroom open plan house so the plugin is situated at the bottom of the stairs. When it has been hot and all windows/doors open we turned it off and then turned back on at night and it still seems effective. Our next option was to call in Juju priests if this hadn't worked! hahaha
