Hyperthyroidism (overactive thyroid disease) is a common disease affecting older cats whereby one (or both) of the thyroid glands in the neck become enlarged and produce excessive thyroid hormone. This is usually a benign enlargement but can rarely (1-2%) be a malignant tumour. The excessive thyroid hormone sets the cat's metabolism into overdrive, burning up energy.
