A little skeptical at first I confess. This "miracle" solution sensible prevent your cat scratching the couch or to his needs in the corridor and yet ... Feliway will calm your cat (well, he calmed mine). Unfortunately I have the impression that it does not work the same way in everyone (each cats behave differently): I went with a friend who wanted to prevent her cat attacking his brand new sofa, it took at least two pchit Feliway day on the furniture ... for one, two a week was enough. If your cat is very sensitive to odors, believe me, it really works. To describe the cat's behavior after he sniffed the place of sprayed Feliway: It seems that the cat is under the influence of drugs (not harmful course). In fact, if your cat tends to be very lively and dynamic (like mine), it will suddenly be quiet, will come to rub you, take long toilets throughout the house and will dodge "instinctively" the sprayed areas by Feliway. I told my vet for reassurance: He sprinkles his Feliway same room for the cat more comfortable.
