A cure for hyperthyroidism in cats.

Cats with hyperthyroidism may show clinical signs and symptoms such as:

  • Behavioral changes
  • Increased appetite
  • Increased thirst and urination
  • Weight loss
  • Rapid heartbeat
  • Eliminations outside of the litter box
  • Thinning coat or excessive grooming
  • Vomiting and/or diarrhea

You know your pet better than anyone, so if you notice any of these signs, give us a call.

What to expect.

A single injection of radioiodine (also known as I-131) can completely cure hyperthyroidism in cats.

When injected, most of the radioiodine accumulates in the thyroid, while the rest is eliminated in your cat’s urine and feces. The radiation in the iodine destroys thyroid tumor cells and effectively cures hyperthyroidism.

Your pet will stay with us for a few days after treatment to allow for a certain amount of radiation to leave their body. We know leaving your pet at the hospital is difficult, but it's critical for their safety and yours, and we use this time for a bit of patient pampering in a quiet environment with lots of loving attention.

The vast majority of cats who receive I-131 therapy never need to be treated again, so you’ll have more time to spend with them in the long run.
