I have one that went hypo after the radio-iodine treatment. She gets a half a pill twice a day of thyroxin. Same as with most meds you would want to start low and go slow with the dosing and monitor with blood work to make sure you find the right dose. Had a heck of a time getting my vet to recognize this diagnosis though and actually had to switch vets to find one that would treat her. Hypert is very common in cats, hypo not as much.
 
My Cootie was diagnosed with hypothyroidism in September after having radio-iodine tx in June. She is currently on levothyroxine 0.25 ml once per day--as a compounded liquid. Her BG levels were very high & unregulated til she started getting the levo--now she's just finishing her OTJ trial (fingers crossed).
 
My Tiger also had the radio-iodine treatment in March of this year-as luck would have it, she wound up with hypothyroid in June. Off topic but within a week of her BW showing hypo, I learned that I also am hypothyroid. :roll: So now we take the me med- Levothyroxine, only hers is compounded into a chicken flavor, which she likes.
 
Interesting that the I-131 has that effect - from one extreme to the other. Grayson's was kind of the same, only his was caused by SRT - stereo tactic radiation therapy - that he had to treat his Acromegaly. The folks at CSU said this may be a side effect, but I only know of one other Acro that became hypo-t. G was on Thyrosin, but from checking on Google, they are all the same, just different names.
 
Although they try to dose the I-131 to take out just enough of the over-producing thyroid gland, they can overshoot, reulting in insufficient thyroxine production and the need for supplementation.

They do inform you of the risks ahead of time.
 
Autumn is hypo-thyroid with her it was caused by injury, at sometime before I adopted her, she was shot in the head, neck and shoulder and one of the BB's pierced her one lobe of the thyroid. My understanding is that one lobe can be damaged or even removed without causing them to go hypo-T but the other one can't be damaged at all without this becoming a side effect. She is on synthoid (sp? not near the bottle atm)
