Hyperthyroidism

Hi there, I'm new to the forum. I have 2 cats. Got them when they were kittens (first time I've ever had cats.) I absolutely adored them. However I got divorced and due to some circumstances couldn't keep them. I searched for a long time to find someone that would let them sleep with them in a bed and give them lots of love and affection. Well, the lady has had them 6 months and doesn't want them anymore. My circumstances have changed and I am able to house the cats and I told her I would like them back. (which she is happy to do). I have 2 issues to address - One of the cats has been diagnosed with Hyperthyroidism (9years old). He is on meds but I wonder if the iodine treatment is a good option. I want him to have a good life. I've read some of the posts on this and plan on taking him to my vet once I pick them up on Sunday. The other thing is my fiance is very allergic to cats. He has been a dear and is building them their own little insulated house off the back porch and then we plan on enclosing the large porch so they have a large area to run around in. Question is how much of heater do I need to put in the little house to keep them warm? I thought of getting one of those heated beds or putting in a small baseboard heater.... is a heater bed enough heat for them? Any ideas would be appreciated. They are such good cats and I'm SO excited to have them back.

speak with a vet or evan two about treatment...

Jazz had the Radioactive Iodine shot and is as good as new. The meds only worked for a couple of weeks then she kept throwing up! It broke my heart to put her in the hospital for 5 days but it was the best thing for her.
