This is a disease seen most commonly in the cat. Since it was first diagnosed, the condition has become common in cats and is increasing still in prevalence. It is a very uncommon condition in dogs. Feline hyperthyroidism occurs due to the development of hyperfunctional thyroid nodules, which are benign. It is rarely associated with malignant thyroid neoplasia (>98% are a functional adenoma of the thyroid gland and many well be palpable, whilst on the small remainder are malignant). | This is a disease seen most commonly in the cat.
