Review: This is Actually Amazing - I was very pleasantly surprised by how well these calmed down my little rescue calico, who’s afraid of humans. She stretches out and purrs on the cushion I put nearby. I ended up placing one in every room. I’ll be buying more.
Review: Works great, on the pricier sider - Works great, feliway is on the pricier side for diffusers for cats. I've never switched up because then I'd have to buy more adapters. I only keep 2 plugged in now but get the 6 pack and make it last.

## Questions & Answers

**Q: Can ceva feliway's refill fit in comfort zone's diffuser?**
A: HI, sorry for the delay.  I only have ceva feliways diffuser.  But looking at the diffuser, I think I could put a refill in Bath and body works plug-in diffuser, meaning I think they are pretty standard.  I would try comfort zone's diffuser if I needed to, tho.

**Q: Is it possible to use the Feliway liquid at the bottom? the diffuser never uses all of it.**
A: I pop off the top on my feliway bottles and condense into another and am able to fully use it. 
You’ll need a flat head and a couple of paper towels bc it’s a bit messy but if you do this you’ll use it all! It’s worth the 5 minutes, I usually get another two weeks worth out of the bottom.

**Q: What is the difference between feliway classic and multicat?**
A: Classic is a facial hormone which is calming. When cats greet each other they rub cheeks as a friendly gesture. Multi cat is a mammary gland hormone and since kittens nurse together,  this helps to reduce stress in cats who live in the same household.

**Q: What's the differance between the Feliway from comfort zone over this Ceva Feliway defusers**
A: 1) Ceva manufactures Feliway, which was the original feline pheromone calming product. 2) Comfort Zone With Feliway contains lower quantities of Feliway. 3) Comfort Zone is less expensive up front. 4) In my experience over the last several years:  4a) For mild/moderate situations (or cats with mild/moderate issues), Comfort Zone helps. 4b) Feliway by Ceva is more effective for severe environmental situational (highly stressful/more chaotic, etc) and for cats with more severe or long-standing issues.

### ⭐⭐⭐⭐ I am seeing a difference in my cat's behavior
*by K***R on July 18, 2020*

I purchased the Feliway Classic Diffuser first at the vet's office to see if it would help with one of my cats' elimination on rugs and furniture. The cat is very skittish, even though she's lived with us for years. I first used it in a large bedroom, but it was plugged in about 10 feet away from one of the places where the cat sleeps. I don't think it had much of an effect. She mostly stays in one corner of the bedroom, but later in the afternoon moves to a different location, which happens to be next to an outlet. I moved the diffuser over there, and I think it is having a positive effect on her. When I pet her in her other spot, she is very vocal, as if she thinks I'm going to take here outside to clip her nails (she hates that). But when I come home from work and approach her to pet her when she's laying next to the Feliway, she is quiet, and gets into a more relaxed position, stretching out and enjoying the attention. Also, the frequency of her elimination on the rug has decreased, so I do think the product is making a difference. I recommend the product, but with some caveats: 1) Probably most effective in smaller rooms. 2) If in a larger room, I think the cat needs to be within a few feet from it, especially if you have a ceiling fan on in the summertime. There was no miraculous change in her behavior, but these refills are inexpensive enough that I am willing to keep using them to see if there is a longer term change in her behavior. I recommend them as a relatively inexpensive refill for the Feliway Classic Diffuser.
