Regular monitoring of the cat’s thyroid hormone levels is also essential to ensure the effectiveness of the medication without causing any harm. If side effects occur, the veterinarian may modify the medication dosage or switch to an alternative treatment to achieve optimal results for the cat’s well-being.
