The clinic is booked through April 2022 and will then be closing later in Spring 2022. We will not be scheduling new cases.

Dr. Doug Evans was the first veterinarian in the Pacific Northwest to be licensed to provide 131I therapy for hyperthyroid cats at the Feline Thyroid Clinic in Springfield, Oregon. The clinic is a special purpose veterinary nuclear medicine facility that provides 131-Iodine therapy for hyperthyroid cats and their people.

Radioactive Iodine (131I) is the safest, best and ultimately least costly lifetime treatment for almost all hyperthyroid cats. There are no radiation side effects for treated cats, owing to the selective uptake of radioactive iodine by "abnormal" thyroid cells.

After receiving a painless injection of 131I subcutaneously on the day of admission to the clinic, cats can go home 4 days later.
