We have a feisty and nervous, easily stressed cat. I was of course advised that plug-in and brand (and tried others too) and I really can't tell if it makes any difference at all and therefore if it performs better than others which I can't figure out either in all fairness... The only thing I saw was that my cat sniffs the plug when it's on and doesn't seem too impressed. I want to trust the hype, but again, it is hard to say what it really does.

Given that this product is quite expensive for something that may be a frequent purchase, I wanted to be sure that it was effective. So far, early morning meowing around the house has stopped so the indications are good!
Delivery: I couldn't believe this product which is in a small box was delivered in much bigger cardboard box that could have fit numerous other items - I know different suppliers are used for different items, but there is no reason to send small products in gigantic boxes.

Purchased this as 1 of my toyger boys was quite hyper and seemed alarmed at most things. His brother was quite laid back. Almost straight away he seems very relaxed and sits still long enough for us to stroke him which we couldn't do before. They have lived with us for 4 weeks now and this weekend has made quite a difference which can only be the feliway. Recommended

Without this my two lads can get very tetchy with each outher - this keeps the peace.

I wouldn't have said my indoor cat was at all stressed, but he was prone to destructive behaviour - things like knocking things off shelves and leaping on to the tops of doors. I got some Feliway and within 12 hours he was like a different cat. He's still got character but he doesn't do things which risk hurting him any more. I noticed that if his behaviour deteriorated, the diffuser was invariably almost empty. I've learned to always keep a refill spare so there's no break in usage.
