Thanks for the information. If his appetite is no longer increased, the medication is most likely working. Usually after 4 weeks, we would retest the thyroid values to see if they are back in normal range. That is a true indicator if the treatment is working. Plus, it is important to recheck kidney enzymes to make sure he doesn't develop any problems there after starting treatment. With hyperthyroidism, the increase blood pressure can mask chronic kidney disease. Correcting it, may just cause the kidney function to decrease. If the levels aren't quit back to normal, then they may need to readjust the dosage some. Other treatment options are using compounded methimazole that you can apply to the skin to be absorb (absorption may not be as good as with the pills), radioactive iodine treatment to destroy the overactive thyroid tissue (requires special facility) or feeding an exclusive diet of Hill's Prescription Diet Y/D. It is iodine deficient and can be used as the sole treatment for hyperthyroidism in cats. Please let me know if you have any other questions or concerns. Hope this helps.
