Hamilton seems to be doing well on the hyperthyroid medication. He seems a little tired for a while after he takes it (right now he's snoozing in a little ball next to the desk). But other than that, he seems fine. We're hoping that all of his other tests will come out alright and he'll be able to have the iodine treatment that could cure the condition. Having him on medication for the rest of his life will be challenging otherwise.
Has anyone else out there had experience with a cat with this condition, or with the medication or treatment options? We're hoping to get some more comments going on the blog -- thanks to Karin, who commented below, for starting our discussion!
