My 14 year old cat was diagnosed with hyperthyroid, put on methimazole for about 2 months, and is now being tested
for myasthenia gravis. I quit the methimazole over a week ago, but symptoms have not improved. I have other cats, so the YD diet won't work because he just goes to eat their food, and I just don't think the radiation treatment is smart in a cat his age, not to mention I do not have the money for it.
