Radioiodine treatment

Hyperthyroidism most commonly affects older cats (8 years and older). It is usually caused by a benign (malignant) growth of the thyroid gland. This gland produces thyroid hormones and when the gland grows it produces too much.

A single Radioiodine dose is curative in around 95% of cats, 5% require a second treatment. Pet Doctors offers discounted re-treatment for all cats treated with Radioiodine Treatment at a Pet Doctors clinic.
