Just an FYI, your vet probably knows this info. If you are sick and have an inadequate adrenal response (ie, your cortisol is not as elevated as it should be by the stress of your illness), you will be even sicker. You will improve with steroids, like Chipper did, but it won't cure or treat the underlying illness. It would be unusual for Addison's to not have abnormal electrolytes (and its pretty amazing if his electrolytes were normal with all the vomiting and diarrhea, but they produce opposite electrolyte changes so sometimes they sort of cancel each other out when you check labs).

So, good for the vets that they are continuing to look and not be satisfied with his initial response to the steroids. Hopefully Addison's is it, as it would be easy to treat.
