What Is I-131 Radioactive Iodine Therapy?
Feline Radioactive Iodine Therapy, commonly referred to as I-131, is considered the gold standard treatment for hyperthyroidism in cats. It targets the root of the condition by destroying the abnormal thyroid tissue responsible for overproducing thyroid hormones. Unlike medications that manage hyperthyroidism temporarily, I-131 therapy is designed to be a lasting or permanent solution.
How it works:
The cat receives a small, therapeutic injection of radioactive iodine specifically formulated for your individual cat.
The iodine is absorbed by overactive thyroid cells.
These abnormal cells are selectively destroyed while healthy thyroid tissue remains unharmed.
Hormone levels return to normal naturally over time.
The treatment is highly effective, low risk, and requires no anesthesia. Most cats need just one injection to achieve long-term results.
Why Feline Radioactive Iodine Therapy Matters
Hyperthyroidism affects thousands of aging cats every year. Symptoms can be subtle at first, but they eventually lead to serious health complications including heart disease, high blood pressure, weight loss, and kidney strain. Timely diagnosis and definitive treatment are essential to ensuring your cat’s longevity and quality of life.
Common signs of hyperthyroidism include:
Weight loss despite increased appetite
Restlessness or hyperactivity
Increased thirst and urination
Vomiting or diarrhea
Poor coat condition
Elevated heart rate
If your cat shows any of these symptoms, early intervention can make a world of difference. While medications like Methimazole can control hyperthyroidism, they require daily dosing and ongoing monitoring. I-131 therapy eliminates the long-term burden of medication management and provides a more predictable, stable outcome.

2. A Cat-Only Hospital Designed for Comfort

That’s why our hospital is exclusively for cats—no barking dogs, no crowded mixed-species waiting rooms, and no overstimulation. Every aspect of our facility is intentionally crafted to reduce stress and create a peaceful, calm experience.
This becomes especially important when it comes to advanced treatments like I-131 therapy. A tranquil and cat-centric environment supports faster healing, smoother monitoring, and a better overall recovery.
3. Recommended by Veterinary Endocrinologists
This treatment is widely recommended by veterinary endocrinologists and feline specialists. It has been used safely and successfully for decades.
Radioactive iodine (I-131) therapy is considered the gold-standard treatment for feline hyperthyroidism. In over 99% of cases, it provides a curative solution with a single treatment.
I-131 works by safely targeting and eliminating abnormal thyroid tissue while sparing healthy tissue. Once treated, most cats return to normal thyroid function without the need for lifelong medication or daily pills.
What to Expect With Radioactive Iodine Therapy
Treatment Overview
What does the treatment involve?
Prior to referral, your primary veterinarian will provide bloodwork, urinalysis, chest X-rays, blood pressure readings, and your cat’s medical history.
Treatment consists of one small injection of radioactive iodine under the skin—similar to a vaccine.
The iodine travels directly to the thyroid gland and selectively destroys the abnormal cells.
Your cat will stay with us for several days so we can monitor radiation levels and provide daily care, comfort, and TLC.
Because demand is already high, we have begun offering a waiting list.
Why You Should Join the Waiting List Now
Hyperthyroidism progresses over time—so even if your cat currently seems stable on medications, planning ahead is smart.
Reasons to reserve your spot:
Limited availability once treatment launches
Prioritized scheduling for early adopters
Continuity of care under Dr. Ashley Love
Access to the most advanced feline hyperthyroid treatment
Reduced long-term medication burden
Better long-term health outcomes for your cat
If your cat is newly diagnosed, medication can help stabilize them until I-131 therapy becomes available. Getting on the list early ensures you are prepared for the definitive treatment when the time comes.
