Feline hyperthyroidism is the most common hormonal disease seen in domestic cats. Commonly afflicting older felines, usually greater than 10 years of age, hyperthyroidism commonly causes other health issues with the heart and kidneys the longer it remains undiagnosed and untreated. Proper diagnosis and medical work-up will result in appropriate diagnosis and treatment recommendations. This all starts with annual blood work that specifically screens for this condition in older felines. We recommend doing thyroid screening starting at 8 years of age once annually and every 6 months after 12 years of age. Early detection leads to early diagnosis and treatment.
