To date, AVS has treated over 700 cats diagnosed with hyperthyroidism, with radioactive iodine-the gold standard for therapy of these cats. When compared to other methods of treatment, radioactive iodine is by far the safest and most effective.

The majority of our cats arrive with a diagnosis of hyperthyroidism. Therefore we do a history and physical exam to confirm the diagnosis and establish the radioactive iodine dose.

These cats receive a filter sterilization subcutaneous injection (just under the skin) on Monday morning. Our staff is here 24 hours while they are hospitalized to monitor them. They are released on Wednesday.

We ask these cats' owners to follow some simple, specific guidelines about handling the cat for 2 weeks after therapy. Owners are provided with oral and written explanation of these expectations.

Two weeks after treatment the cat will return to AVS for a Geiger counter check and four weeks after should return to their referring veterinarian for a follow-up T4 blood test. These results will be sent to us for our files.
