Radio-Iodine Therapy
Targeted treatment for thyroid conditions
Radio-iodine therapy (I-131) is the gold-standard treatment for hyperthyroidism in cats and certain thyroid tumours. It is a safe, highly effective, and minimally invasive procedure. A single injection of radioactive iodine selectively destroys overactive thyroid tissue while preserving surrounding healthy tissue. Most cats are cured after a single treatment. Our team guides you through every step of the process, from initial consultation to post-treatment follow-up.

Frequently asked questions
Yes. Radio-iodine is considered the safest and most effective treatment for feline hyperthyroidism. It targets only the overactive thyroid tissue, leaving healthy structures intact.
Cats typically require a short hospitalisation period of a few days following treatment to allow radioactivity levels to decrease to safe levels before returning home.
The majority of cats return to normal thyroid function within 1 to 3 months. Follow-up blood tests are scheduled to confirm success and monitor overall health.
