Oh boy, that's stressful for sure. I still have my issues w/Specs picking on Boo but since he's been on Clomicalm, it's calmed down considerably. When my RB Peeka was alive, she picked on my sweet Pidge like you wouldn't believe, stalked her, waited around corners so she could jump her, etc. Poor Pidge spent most of her days and nights hiding under my bed. That was not a good way to live! It wasn't until Creamsicle came into the home that she stopped doing it and I have no clue why. I didn't know about Clomicalm then or she would've been on it, too. I'm sorry that it seems to have an adverse effect on your cat. I hate to sound like a drug pusher but Dr. Lee said that they're seeing much success w/Prozac for cats and he says that it starts working almost immediately. If you can't separate them to any degree, maybe Prozac will work for you. That's such a stressful situation for all of them and especially for you. I feel for you, I really do. And to add the pee and pooping to the mix, UGH. I wish I could give you better suggestions other than drugs. Believe me, I tried everything, too, as I'm sure you have. Hang in there. I just vented on PT a little while ago and I already feel better. You will, too.
