Radio-iodine (I-131) Therapy: Information
- Subject to your Veterinarians recommendation and referral for I-131 treatment.
- Radioactive Iodine (I-131) does not make cats feel sick!
- I-131 is a non-painful radioisotope administered by a single injection.
- I-131 does not damage healthy tissue and does not cause harmful side effects.
- The radioactive iodine is transported directly into the thyroid gland upon entering the body. It remains in the thyroid for 48-72 hours, destroying the abnormal thyroid cells, thus curing the disease.
- Colorado law mandates isolated hospitalization for a minimum of 3 days. This can be as long as 7 days.
- Owners are not allowed to visit their cat during the isolation period.
- While hospitalized with us, your cat will stay in our radiation “kennel”, inaccessible to cats not treated with iodine.
- Litter is changed regularly and fresh food and water are available at all times.
- Please inform us of any special dietary requirements so we can make their stay with us as comfortable as possible.
- Please bring any medications your cat is currently prescribed. We will administer as directed by your referring veterinarian.
