Hello Fellnase owner / inside, my makiert more recently, and by the reviews I thought, I'll try the Feliway spray times, but for me it has not worked. In my already has an XXL casket, but what's in there, it must be removed immediately, otherwise he makiert back in its usual place, respectively, it is protest pee. Well, on the day that's ok, but if my Schnute night goes to the casket, and I fall asleep I get with nothing, so I can not clean it. This will be the problem with my cat, and therefore the Spay has unfortunately not with Him the desired effect. But you can try it quiet times, when it then so what brings, the better.
