what are iodine shot for
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 (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.
