Follicular cell neoplasia of the thyroid glands occurs most often in domestic cats, dogs, and horses, and infrequently in other animals species. Variable clinical signs of hyperthyroidism, such as weight loss, vomiting, diarrhea, heart murmur, polyphagia, hyperactivity, and a palpably enlarged cervical mass, may accompany the neoplasia, especially in cats.
