Purchased on the site. It is not given, Feliway, but here this still costs two to three times cheaper than in my veto which sells 37. I have two male cats, and although they are castrated, they sometimes fight like cats and one of them, a rather jealous nature tends to mark his territory everywhere! (If you know what I mean!). Only this makes them much quieter and stops pees unfortunate! So you have to buy regularly (charging takes about a month). Wildlife experts on the sites where we provided before, it's even more expensive than here. I admit I did not even know that there was Feliway for sale here (I do not use Amazon as a usual Super Market, but finally here, for the price, I change my mind)! So if you have Matous not always wise, magical product that will transform them into completely harmless and odorless fluff :)
