Aw Clyde is a beautiful boy! He looks somewhat like my gray kitty Yodie and she happens to be a pee cat, too, but as I mentioned to you in a PM, Clomicalm works wonders. I do understand why you're hesitant to try it, though, if Clyde has stomach issues. Good luck w/this. I know how frustrating it can be but don't give up. It'll turn around. Clyde is counting on you.
