Radioactive Iodine Therapy

Thyro-Cat Services and Treatment

The preferred method of treatment for cats (and humans) with hyperthyroidism is Radioactive Iodine (I-131) Therapy. Treatment is as easy as one injection just under the skin, much like a routine feline vaccine. I-131 feline hyperthyroid treatment is safe and the product travels quickly from your cat's bloodstream to the diseased thyroid tissue. After being absorbed by the the thyroid, the I-131 destroys the overactive portions of the gland.

A short stay (3 to 5 days) in the Thyro-Cat hyperthyroidism treatment facility is required by law until the level of radiation is at an acceptable level.

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

  • Very limited amount of stress (almost none) imposed on your already sick kitty
  • No anesthesia is required
  • No surgery 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.
