Review: IT REALLY DOES WORK!!!! - This product is a lifesaver! We introduced our new kitten to our older cat too early. Our older cat was extremely unhappy, hissing, growling, and refusing to eat. She wasnt eating her treats either and not letting us near her. We were worried we'd made a mistake, as she'd never been this aggressive or behaved like this before. Little kitten was also scared and growling. Desperate, I tried this product hoping for a change. To my surprise, it worked almost immediately. Our older cat calmed down and relaxed. The next day, she was playing with her new brother and fully accepted him. Highly recommend!
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.

I bought this because a few people in work said it worked on their cats. I didn't see any calming effect on our kitten.
