Has Shadow just started doing this, or has it been ongoing? Did he and Panther used to play a lot together? Do you think maybe he wants a younger cat to romp with??

My foster Furbee sounds like your Magic. She shrieks like she's being torn apart whenever any of the other cats even walk near her. I've had her with me for a year and a half now, and she's still this huge fraidy cat! She's the biggest of them all, but she is just not a social girl. She tolerates petting from me, and a few others, but will nip too. I think she just needs a home where she is the one and only cat, with some very laid back people who will give her time to settle in. When she was at the shelter I volunteer for she was petrified and wouldn't eat. At least it's better for her here, but until she finds a forever home, she's with the others... still love her to pieces though. She's sweet in her own ways, and would be a wonderful only pet, only she can't be that in my house, lol.
