Josie at the Vet Hospital.

I admitted Josie into hospital today. They ran tests and said she is in very good health.
They will administer the radioactive iodine tablet on Friday morning.
The dose they choose depends on her TT4 level and also when they feel her thyroid, how large the goiter is.
They rang me today and said she is eating well, so she is not distressed. But it's Friday morning they give her the tablet, and the night before they give her an injection to stop her vomiting the tablet.
There are two risks, one is she still may vomit the tablet (the tablet costs $650), and the other risk is her thyroid might go too low and stay too low, i.e. she might end up with HYPO thyroidism which would require medication for the rest of her life. Only about 1% suffer that. I asked the vet is it because they got the dose wrong, and he said yes. Josie's TT4 level will go too low in the beginning and then it normalises after about a month. The radioactive Iodine kills the abnormal cells in the thyroid.
For the last week I put an old sheet on my pillow and slept on it every night. Then I cut it up into 7 pieces and placed them in a bag for them to put in a piece every day while she's in isolation.
The vet said he'll make sure they put a piece in every day.
Josie was 10 years old on the 3rd of June. It's a guess of her birthday.
