Is my cat a candidate for radioactive iodine?
Cats should be relatively stable before being considered for radioiodine therapy. Cats that have clinically significant co-morbidities may not be good candidates for treatment, considering the length of boarding and minimal monitoring and treatment capabilities during the immediate post-treatment hospitalization.
How long can a cat live after radioactive iodine treatment?

Can cats take tapazole?
The disease is usually fatal if left untreated. Medical therapy for feline hyperthyroidism (methimazole - Tapazole®) is required daily, is a life-long treatment, and does not cure the cat's hyperthyroid condition. The difficulties associated with giving pills to cats often causes stress to both the animal and owner.
Can Iodine 131 be used on cats?
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.

How does Iodine 131 therapy treat hyperthyroidism?
Iodine is an element normally taken up in large amounts by the thyroid gland, even more so in cats that are hyperthyroid. When a radioactive form of iodine is given to hyperthyroid cats, the radiation destroys a portion of the thyroid gland.
Which cats can be treated with radioiodine (Iodine 131)?
Radioiodine is an appropriate treatment for cats with hyperthyroidism that are in a stable medical condition. Because these cats are emitting radiation during this treatment, only basic care (feeding, cage cleaning) is provided during the isolation period to prevent excessive exposure to personnel.
How long will my cat be in isolation?
The length of isolation depends on how quickly the levels of radiation emitted from your cat decline. For most cats treated at the University of Tennessee, this period lasts approximately 6 to 10 days, making the total stay in the hospital approximately 8 to 14 days.
What is involved in a pre-treatment evaluation?
Blood and urine tests and chest x-rays are made to evaluate the overall medical condition of your cat.

The radioactive iodine is administered as a single injection under the skin in the region of the inner thigh. Because of the nature of the injection, we generally will administer a small amount ...
Why is radioiodine not concentrated in thyroid tissue?
Therefore, the radioiodine is concentrated by the hyperactive, abnormal thyroid tissue. Because the normal thyroid tissue becomes atrophied (decreased in size and ability to function) in the hyperthyroid patient , the normal thyroid tissue itself should not concentrate the radioiodine.
Why do cats stay in the hospital longer with kidney disease?
Due to the removal of iodine through the kidneys, cats with preexisting kidney disease may have to stay longer because the radioiodine may not be removed from the body as quickly. The patient will be monitored at regular intervals to determine when they are able to be released.

What are the complications of radioiodine therapy?
These complications include cerebrovascular events (i.e., strokes) and the premature exacerbation of pre-existing kidney disease. Luckily these risks will diminish in time following successful radioiodine therapy and a return to a persistently normal thyroid level.
What is the risk of radioiodine?
1.) Risk to the patient: The radioiodine (I -131) used to treat thyroid disease in people and animals emits both gamma rays and beta particles. The beta particles, which are much more potent forms of radiation, travel an average distance of less than 1 mm. Because of the short distances they travel they never exit the patient ...
Why do cats never exit the patient?
Because of the short distances they travel they never exit the patient and as a result no one other than the patient is at risk from exposure to the beta particles unless they internalized the radioiodine excreted by the patient. In cats > 95% of the radioiodine is excreted in the urine.
Can you put radioactive iodine in your cat's urine?
The good news is that virtually every client will already take steps to avoid this, even when radioactive iodine in their cat's urine is not the motivation.
Does iodine help cats with thyroid disease?
When it comes to survival, the studies that have been done show that cats cured of their thyroid disease by radioactive iodine live much longer (up to twice as long) when compared to hyperthy roid cats treated by methimazole. So in this case the targeted radiation exposure is actually increasing survival for these patients.
Does radioactive iodine cause thyroid cancer?
Hence for a transient period following radioiodine therapy, the patient's urine contains excreted radioiodine which will emit beta particles as it continues to decay. The risks associated with low level ingestion of radioactive iodine relate to an increased risk of developing thyroid cancer.
Radioiodine Procedures Pre-Referral Data
Procedure
- Our protocol includes an imaging study of the thyroid prior to the I-131 therapy. Not only will the scintigraphic study confirm the diagnosis of hyperthyroidism in cats that do not have a palpable thyroid nodule, but it will also identify a relapse of hyperthyroidism following a thyroidectomy. It will also evaluate for the possibility of ectopic thyroid tissue. The scintigraphic study is usually d…
Post-Treatment Procedures
- At the time of release, the radiologist will meet with the owner and explain the post-treatment procedures. For the first two weeks following treatment: 1. Limit close contact (holding close to your own neck, sleeping next to) with your cat to a maximum of 30 minutes per day per person. 2. Keep your cat indoors. Scoop urine and fecal clumps from the litter box twice daily. Use a flusha…
