The frustration is quite evident in your post.

My Vita is spraying, she is stressed with all the comings and goings of animals here last year, and the arrival of Tommy & Tuppence in January did her in. I am using the Feliway on a strip of fabric I slip over her collar (so the scent is always with her) and that is working. I did that for a month and stopped, she was fine for 2 months and just started spraying again this week. So the fabric is back on her collar and getting sprayed daily.

I know someone asked if Cami could stay in one room be herself for a while to let her calm down. It does sound like stress on her part; having the other cats stalk her, and mommy hollering at her, is not good for any of you.

I wish I had a magic wand to make it all well for you. {{HUGS}}
