Kelly, I sure hope that Micah gets better soon and that this medicine will help him. I'm so glad that he seems to like your other cats. I can't wait to hear about their introductions. Please keep us posted on his condition. I know that my Sunny is a very nervous high strung cat and he's only half aby. He's never had a diarrhea problem though. Good luck. All fingers and paws are crossed for a complete and speedy recovery.
