This stuff saved my submisive male (Dally) last year he escaped through an open window (he worked and worked at the fly wire until he made a big enough hole) and went for a wonder in the middle of the night. He as then chased back inside by a tom (who wasn't desexed) back through the window and my very bossy tortie (Tobie) attacked him. She broke two of his back claws so his feet were in a bad way and she wouldn't leave him alone it took approx. 3mths to get them to be friends again. Slowly but surely and with a lot of feliway we also had to start again and board them at the vets for a couple of days while I tried to "change" the house so it looked like new ground. I will always have a bottle in the cupboard just to be on the safe side. Sorry this is very long. lol
