Hi FL: I see you are a newcomer. Welcome to Pet Talk. It's always nice to see new faces around here.

I'm owned by 2 kitties, Max the Persian is 11 and Speckles the Tabby is 17.

I have not had any experience with hyperthyroidism at all so I don't have any advice to give you. I'm interested to see what responses you get because, having geriatric kitties, I too could be in your shoes one day.

I seems to me that Cataholic has had experience with this.
