What is Feline Hyperthyroidism?

Feline Hyperthyroidism is a disorder that occurs when the feline thyroid gland produces an excess of thyroid hormone. An excess of thyroid hormone affects all of the cat's organ systems.

Feline Hyperthyroidism (or cat hyperthyroidism) occurs in middle aged and senior cats. Both feline sexes and all breeds are equally at risk.

The thyroid gland is butterfly-shaped and is located in the neck region of the cat. Hyperthyroidism is caused by a tumor in this gland that produces excessive amounts of thyroid hormone. Ninety eight percent of these tumors are benign (adenoma) and two percent are cancerous (carcinoma). Seventy percent of cats have both lobes of the thyroid gland affected.

Cat Hyperthyroid Diagnosis and Treatment

Thyro-Cat Centers treat feline hyperthyroidism with Radioiodine therapy.

Thyro-Cat hyperthyroid treatment facilities are built exclusively for I-131 treatment of feline hyperthyroidism. They are fully licensed by the State Departments of Health and the Nuclear Regulatory Commission. Our centers are spacious, comfortable, climate-controlled and complete with videos for the cats to enjoy.

Thyro-Cat referral cases are all reviewed by our veterinary specialty team consisting of board-certified radiation oncologist, internists, cardiologist, radiologists and a radiation safety officer. These team members collectively assure that each cat's needs are met prior to, during, and after   I-131 therapy for cat hyperthyroidism.

Thyro-Cat feline hyperthyroidism treatment centers are conveniently located in Danbury/Brookfield, CT; Holbrook/Long Island, NY; Syracuse/Fayetteville, NY; and Stamford, CT.

Radioactive Iodine (I-131) Therapy for Feline Hyperthyroidism

Treatment of cats for feline hyperthyroidism with Radioactive Iodine (I-131) is the preferred method of therapy (and well as in humans). It is as easy as one injection just under the skin, much like a routine feline vaccine. I-131 is safe and effective. A short stay (2 to 5 days) in the Thyro-Cat hyperthyroidism treatment facility is required by law until the level of radiation is at an acceptable level.

The I-131 hyperthyroid cat treatment is absorbed quickly into the cat's bloodstream and the diseased thyroid tissue. Once in the thyroid, it destroys the overactive portions of the thyroid gland.

Radioactive Iodine I-131 feline hyperthyroidism treatment has the following advantages over medical and surgical treatments for feline hyperthyroidism:

  • No anesthesia is required
  • No daily medication
  • Does not destroy healthy tissue
  • Does not damage other tissue or organs, including the parathyroid glands
  • Does not have harmful side effects
  • Returns thyroid function to normal usually within one month
  • Is cost effective

Thyro-Cat is an approved specialty facility with State Department of Health and Nuclear Regulatory Commission for use of I-131.
