Preparation & Timelines

If you are interested in radioiodine after reading the Client Information Packet and you would like to continue the process, please email us at [email protected] or fill out the questionnaire below.

Client Information Packet

Our Questionnaire

A reply with answers to the questionnaire (as well as you are able) is our trigger to continue the referral process. 

Steps that you need to take:

  • Contact all veterinarians that have seen your cat in relation to hyperthyroidism to email us their records.  We need all information from one year PRIOR to the diagnosis of hyperthyroidism to the most recent visit, all notes, and lab work.

  • Responding to the questionnaire is what starts the referral process so we can see your cat.

Before Your Phone Consult

Please read over the "Client Information Packet", our FAQ page, and the "Treatment Prep Packet". Please watch this video prior to our consult and be prepared with medical questions for Dr. Decker.

The video covers the basics that we review with every client considering radioiodine.

  1. How the injection is given and how radioiodine works in the body

  2. Speaks to the safety of the injection for the rest of the organs other than thyroid cells

  3. Highlights the reason for our 95% 1st injection cure rate

  4. Being a radioactive kitty in the hospital

  5. Describes our wonderful facility and the care we provide

  6. Sets expectations for our limited ability to monitor, test and treat radioactive patients while there are in isolation after the injection

  7. Touches on pre-radioiodine testing

  8. Follow-up monitoring and communication between our team, you, and your vet

It is very helpful for the most productive phone consultation if you have a good grasp of the process including diagnostic testing. These items will lay a good foundation that we build on during our conversation.

Before your Pre-Radioiodine Preparation Appointment

Helpful Documents

  • Email us a photo of your gabapentin bottle so that we can see both the strength and the dose. Alternatively, you can bring the bottle with you to the appointment. 

  • If you have not already done so, download, then fill out and return the Cost Estimate form via email at [email protected]. If you are unable to complete the forms digitally, we can provide paper copies.

The night before the Meet and Greet

  • Give the Gabapentin as directed

The morning of the Meet and Greet

  • Give the Gabapentin as directed

  • If your cat does not get car sick, you may give them ½ portion of breakfast.

  • Plan for ~20 minutes for the drop-off, more if you were not able to send us the completed cost estimate ahead of time.

When you arrive

  • Please stay in your vehicle. Do not come into the lobby.  This is to reduce the stress of your cat.

Before Radioiodine Treatment Appointment

4 Weeks Prior to radioiodine

  • If you are feeding your cat Hills Prescription Diet y/d, start transitioning to the new diet. STOP y/d after a 3–4-day transition, and be 100% OFF y/d at 3.5 weeks before radioiodine.

1 Week Prior to radioiodine

  • Stop Methimazole unless otherwise directed. This is to help protect the normal thyroid tissue from taking up radioactive iodine.  Some of the signs of hyperthyroidism may return in the intervening time.  Please feed extra food to reduce weight loss and contact your veterinarian if you have any concerns. 

  • Re-read Dr. Decker’s meet-and-greet email regarding notes that are specific to your cat. Notify us if there are any changes to the plan.

  • Re-read the  “what to bring” and sample discharge statement. These contain important information to help you prepare for your cats' stay with us and your home for post-radioiodine housing.

  • Download, fill out, and send to us the documents “I-131 permission to treat” and “I-131 hospitalized care information sheet”.  These can be returned to us via email at [email protected].  If you are unable to complete the forms digitally, we can provide paper copies.

  • Keep your cat indoors unless you have a patio or fenced yard.  We've had to decline treatment when indoor/outdoor cats have come in with wounds from outdoor "adventures" - and charge a $300 unused radioiodine dose fee. 

  • Apply flea medication 3 - 7 days before radioiodine unless you've already done so within the label instructions of your flea product. Please note: 

  • We will apply flea medication if it has not been done.

  • Unfortunately, we cannot have a Seresto collar on the patients for safety reasons. 

  • Your cat must be stable to be admitted to the hospital (eating, vomiting, and diarrhea controlled, no sneezing, normal urination).  Please alert us ASAP if any of these occur so that we can stabilize.
