Review: It's working!!! - We have a big alpha cat that always throws tantrums and bullying his sister. Day 1, it shows positive results. He was calm, even with the birds in the window he usually attacks, now he is just watching from afar. Aggression towards his sister now reduce to just staring to her. He stopped peeing in the sofas. Now become clingy and starts sleeping besides us in the bed. What a wonderful product!!!

## Questions & Answers

**Q: Does the Feliway diffusers have a automatic overheating shut off?**
A: Don’t buy it won’t fit in to your outlet plug. It’s only made for foreign outlets

**Q: Does the Feliway diffuse have a overheating shutoff?**
A: YOU NEED TO ADDRESS THE MANUFACTURER SPECIFICALLY. I did not see it mentioned and it seems if it did it would be promoted as definite benefit. I am thinking it does not. Which now mentioned seems little scary.

**Q: I can't seem to find this product in the us. is this uk version compatibile with us feliway diffusers?**
A: No, definitely not! It is for a 220 volt European outlet only! I did not notice it was from the UK and got stuck with it because there is no return! :(

**Q: Will the refills fit diffusers for the usa?**
A: I would not chance it since it was able to fit us items. You also cannot return

### ⭐⭐⭐⭐ Mostly it seems to work well
*by G***L on 10 March 2025*

Mostly, it does seem to work. We were tired of 3 males (all neutered) in particular not being able to tolerate being near each other and constantly fighting. I’ve had this thing running a couple of weeks now, mostly the fights have stopped all except for one cat who wants to play whilst the others don’t which sometimes ends in fisty cuffs. I can live with that, before it was constant.
