I had a scare with my cat Deirdre and hyperthyroidism. It turned out not to be her problem but I did all the research on it and had decided that because of her age I would go with the radioiodine. I went to the website of the place that would do the shot and I really liked they way they seemed to run things. They have a hospital in Pittsburgh also. Although you being in Lancaster I am not sure that would be any closer. Your Callie is only 10 years old so you could have many many years with her still. While the radioiodine is expensive when you look at how many years she will be on the meds you would most likely end up saving money with the shot. I ruled out surgery because it was just tooo risky in my book. From all I have talked to the shot is very safe and it is a cure not just a treatment.
