What Is Feline Hyperthyroidism?

Feline hyperthyroidism occurs when a cat’s thyroid glands produce too much thyroid hormone (T4), leading to symptoms such as:

• Weight loss despite increased appetite

• Hyperactivity or restlessness

• Vomiting or diarrhea

• Increased thirst and urination

• Poor coat condition

If left untreated, hyperthyroidism can lead to serious complications, including heart disease and high blood pressure.

What Is I-131 Therapy?

I-131 therapy uses a small, targeted dose of radioactive iodine to destroy overactive thyroid tissue while leaving healthy tissue unharmed. It’s a one-time injection under the skin—similar to a routine vaccine—and has a 95-98% success rate in curing hyperthyroidism in cats.

Benefits of I-131 Treatment:

• Curative in most cases

• No anesthesia or surgery required

• No daily medication or diet changes needed

• Targets only abnormal tissue

• Minimal side effects

• Long-term cost savings

What to Expect:

1. Initial Evaluation: We’ll perform diagnostic tests to confirm hyperthyroidism and assess overall health, including bloodwork and imaging if needed.

2. Treatment Day: Your cat will receive a single injection of I-131.

3. Short Hospital Stay: Due to safety regulations, your cat will stay in our specialized radiation ward for a few days until radiation levels drop to a safe threshold.

4. Follow-Up: We’ll provide guidance for monitoring your cat post-discharge and schedule follow-up tests to confirm treatment success.

Is My Cat a Candidate?

Most hyperthyroid cats are eligible for I-131 therapy. However, we may recommend additional diagnostics if your cat has concurrent kidney disease, heart issues, or other complicating conditions.
