Radio-iodine treatment of hyperthyroid cats.
Thirty-two elderly domestic shorthaired cats (mean age 12.9 years) were treated with radioiodine (131I). The dose of 131I administered ranged from 39 mBq to 134 mBq. Twenty-eight cats became euthyroid after treatment, one became hypothyroid and three remained hyperthyroxaemic. Two of the hyperthyroxaemic cats were successfully re-treated with 131I. Five cats died from concurrent diseases within one year of treatment. The administration of a dose of 131I selected by assessing the severity of the clinical signs, the size of the thyroid gland(s) and the serum level of thyroxine was an effective treatment for hyperthyroidism.
