Review: Kept my cats calm during the house move - This product really works to keep the cats calm in the house and was really grateful for when we done a big move.
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 the optimum refil fit the classic plug or do you have to purchase the plug too**
A: They fit the classic plug

**Q: Can these be used with the plugin adapter that is used with standard Feliway refills ? I have 2 brand new plugs, so hoping I can use them with these.**
A: Yeah! Thats what I do. I chop and change the refills around every few months using the same adaptor :)

**Q: How many of these should I put in the house. Just one? Or one in each room? Please can you advise. Thank you**
A: One diffuser covers 70 square metres or 750 square feet - so depending on your house size - but I feel one on each floor is good

### ⭐⭐⭐⭐ Good need more than one
*by M***R on 22 January 2026*

The Feliway refill did help calm our cats a bit, especially with general tension around the house. We noticed a mild improvement rather than a dramatic change. One diffuser wasn’t enough for our home though — we needed two to cover the space properly for it to be effective. The main downside is the cost, as it becomes quite expensive when you need multiple refills. It does work, but it’s not a cheap solution. Worth trying if your cats are stressed, just be aware one unit may not be sufficient.
