Thank you, that’s great to know you had such a good experience at RadioCat. I’ve heard them mentioned a few times. From what I understand, scintigraphy is about personalizing the radiation dose to limit the chance of iatrogenic hypothyroidism or persistent hyperthyroidism post treatment. Here’s a write up about it:

I think maybe I’ll see about using that clinic.
My fear pre treatment is that rising thyroid hormones will make him feel anxious or poorly enough to run off (which would be very unusual for him, he’s a home body, but I don’t know how he’ll feel once his thyroid is over producing again), and then post treatment he’ll be so freaked out by the experience that there’s the same risk. He’s a very sweet cat and has never been difficult at the vet but it definitely stresses him a lot to go somewhere new & meet new people. For example, when he goes to the vet, I lock him in the tack room when we get home instead of just letting him loose, so he can chill and remember he’s home and safe. But days away is different than a 20 minute visit.
I do always worry when pets have to go be hospitalized for something, but there’s just this extra level when it’s a cat that’s really particular about his place and people, and the only thing keeping him around is his desire to be here. I’m generally not a fan of outside cats and everyone else is strictly indoor only, but we trapped this guy as a starving adult stray. Not only has he clearly always been outside, but he’s really good at his job and happy with his life.
Did you see a change in your cat for that week or two after you stopped methimazole? I’m not sure what to expect.
