Oh gosh Tracey, I'm sorry to hear about Storm. (Great news about Starr being healthy and feeling like a normal cat though). I had issues with Rocky marking cat beds and various things around the house and I took Medusa's advice about the Clomicalm. It has really helped. I can only get it in a cream form from a compounding pharmacy but it's nice because no pilling, I just rub it in his hear. We are on our second 30 day supply and now I only have to use it about every 3-4 days. It stopped the marking and his aggressive behavior towards Scout. When he quit picking on her so did the others thank goodness. He doesn't seemed drugged on it like with Valium - just mellow. Maybe Pearl could use a little to help her stop picking on Storm.
