Dr. Lera talks about feline hyperthyroidism with Pele, a 17-year-old domestic short hair cat. Hyperthyroidism is characterized by the overproduction of thyroid hormone and a subsequent increase in metabolic rate. This disease is common in older cats. Although the thyroid gland enlarges in hyperthyroidism, it is usually a benign or non- malignant change. Fewer than 2% of hyperthyroid cases in cats involve malignant thyroid gland tumors. Many organs are affected by hyperthyroidism, especially the heart.
