Thanks! I got the pills, but haven't given him any yet. I'll probably start them tomorrow morning with his breakfast.

I'd love to get the radioiodine treatment, but for one thing it's $900 (for one shot!) that I don't have right now , but the really bad part is they make the cat stay for up to a week at the facility that does it (not my local vet's, they have to be sent to a special place that does this treatment) because the cat is actually radioactive after the treatment. It would be so hard for all of us (me, my SO, Bo) to be separated so long. I'd be a total worry wart.
