At Angell, we offer expert care and cutting-edge treatment for feline hyperthyroidism using radioactive iodine (I-131). This highly effective therapy targets and destroys overactive thyroid tissue, allowing normal thyroid function to resume. Administered by our specially trained staff, in collaboration with our two staff veterinarians, I-131 is a safe and proven solution for your cat’s health. Our team works under the guidelines of the Massachusetts Radiation Control Program to ensure the highest safety and efficacy standards.
