Led by Dr. Ashley Love, BVMS, DABVP (Feline Practice), our feline-only hospital is proud to once again offer this gold-standard treatment to cats in the Las Vegas area. I-131 therapy has not been available locally for more than three years, and we are excited to bring this advanced, life-changing option back to our community.

Meet Dr. Ashley Love, a dedicated feline specialist at Las Vegas Cat Hospital, offering compassionate and fear-free veterinary care with her advanced expertise.

Understanding Feline Hyperthyroidism

Feline hyperthyroidism is a common condition in older cats. It occurs when abnormal thyroid tissue produces excess thyroid hormone. This can lead to various symptoms, including:

• Weight loss despite an increased appetite

• Vomiting or diarrhea

• Restlessness or vocalization

• Increased heart rate and blood pressure

• Heart-related complications over time

  
  

If left untreated, hyperthyroidism can significantly affect a cat’s quality of life. Recognizing the signs early can make a big difference.

Why Choose I-131 Therapy?

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.

This treatment is widely recommended by veterinary endocrinologists and feline specialists. It has been used safely and successfully for decades.

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.

Will My Cat Experience Side Effects?

There are no direct side effects from the injection itself. Cats do not experience nausea, hair loss, lethargy, or appetite loss from I-131 therapy.

As thyroid levels normalize, some cats may go through a short adjustment period with mild changes in appetite or energy. Our medical team works closely with your referring veterinarian to ensure every patient is carefully screened beforehand and supported throughout the process.

Because most hyperthyroid patients are senior cats, we take extra care to identify other medical conditions prior to treatment. On rare occasions, an unrelated medical issue may arise during or shortly after hospitalization, and we are prepared to address those situations promptly.

Is Radioactive Iodine Safe?

Yes, I-131 therapy is a proven, safe, and effective treatment. With common-sense precautions after discharge, the risk to people and other pets is minimal—often less than the exposure you’d receive on a long airplane flight.

Will My Cat Miss Me?

Of course, your cat will miss you—but probably not as much as you’ll miss them.

Your cat’s stay is relatively short, and their accommodations are designed with feline comfort in mind. We use calming colors and music, Feliway diffusers, and even HD cat videos. Our team spends as much quality time with each patient as is safely possible.

For cats who are more anxious or very attached to home, we’re happy to work with you and your regular veterinarian to create a plan that minimizes stress. Think of it as a spa visit that doesn’t just relax your cat—it cures their disease.

What Should I Bring?

• We provide all meals, but you’re welcome to bring a favorite food or treat.

• You may bring a small comfort item that smells like home (such as a T-shirt or pillowcase). Please note: any items brought will not be returned.

  
  

What About Other Medications?

Please let us know when scheduling. We can accommodate most medication routines and will review everything with you in advance.

What Payments Are Accepted?

We accept:

• Major credit cards

• CareCredit

• Cash

  
  

A non-refundable deposit is required at the time of scheduling.
