I'm so glad that she's feeling better. Yes, I would say that her vomiting is probably a part of her illness. My Storm is also on just 1/2 pill of pred every day or else he'll also vomit. So far it's done the trick and he hasn't gained a lot of weight like my RB Starr did. I don't know how old Ellie-mae is but my vet told me to stop all vaccines on Storm since he's over 10 years old. I hope that the reduced pred doseage each day will help her. It will help any inflammation she may have. Lots more prayers and positive thoughts are being sent her way.
