Feliway? Comfrot Zone Feliway?

Ok, so I was thinking about getting that feliway diffuser but I'm a bit confused as I seem to be finding two types. One is the Feliway, and the other is the Comfort Zone with Feliway.

Any help on what the difference is, and oppinions on which one is best would be greatly appreciated.

Thanks!

Thanks for moving this for me! I wasnt' sure where to put it since it wasnt' really a behavioral question. hehe

I think the "comfort zone" is the actual difuser...you use the feliway with it. I bought two of them for my kitty that's been acting very afraid, skittish and just not himself. It's definitely calming him a lot! I hightly recommend this product!
