Jeri, I am sorry to hear Krissy might have Cushings. If she does, or if you want much more info on Lysodren, treatment, types of Cushings etc, there is a wonderful forum full of Cushings owners where you can ask questions, find out more as well. Has your Krissy been tested for diabetes too? Cushings can be a very difficult one to diagnose.
Here is a link to the cushings forum:
