I hope that the new meds will be able to help Mystic. I also know a lot about prednisolone. My RB Starr had to take it and it did make him put on so much weight that it affected his health. Storm is also on it and he's done very well on it. He can get very hungry though but he also has hyperthyroidism and is on medicine for that too. Hopefully Mystic won't suffer from any bad side effects. Lots of prayers and positive thoughts are being sent his way.
