Radio Iodine

Cat Radio Iodine - Feline Hyperthyroidism TreatmentFeline Hyperthyroidism & Radio-Iodine (I-131)

Feline hyperthyroidism is the most common endocrine disease in cats. Early treatment is key!

Left untreated, hyperthyroidism will ultimately kill the cat. The disease creates a hypermetabolic state which has a devastating effect on all the body's systems, especially the heart and the kidneys.

Our non-invasive alternative to risky thyroid surgery is stress free, and over 95% effective in completely CURING the cat with one treatment!

After a single injection of radio-iodine, cats stay in our comfortable nuclear medicine ward until their radiation measurements drop to a safe level. Most cats can go home in as few as 3 days. (Severely hyperthyroid cats will stay longer.) These patients love to be at home, and we return them just as quickly as possible! The best news of all is that we return a patient who has been CURED.

Most patients adapt to the daily routine of eating, sleeping, and watching our artificial fish tanks. The accommodations are spacious, and our negative pressure cage ventilation system gives a constant flow of fresh air that is continually exhausted out of the building. Skylights provide natural light. It’s like being at the kitty spa! We give your cat the very best care, and our nurses give you daily progress reports by telephone or by e-mail.

Your cat does not have to live with this disease! If your cat has been diagnosed hyperthyroid, give us a call at 303-622-5419, or 877-663-6369. Our nurses will answer all your questions about our I-131 CURE. If you prefer, you can e-mail our nurses: nurses@catspecialist.com

A Peek Behind the Scenes at our Radio Iodine Facility

The nuclear medicine treatment and boarding site is a restricted area according to state regulations, however, we want to share a glimpse of where these kitties get to hang out after their treatment. It's pretty nice! Complete with sky lights, over-sized cages with a balcony, very friendly house-keeping service, bottled water, and a plethora of food options (and you can bring your own too!) - this isn't a bad place to spend a few nights! There is an oversized cage for energetic kitties or those that stay longer after treatment. We, as a staff, have a lot of paperwork and red tape to maintain this facility, but it's all worth it to help cure cats of hyperthyroidism.
