I've been reading all I can find on hyperthyroidism but I find discrepancies in what I read. Can a hyperthy cat have iodine? Most things I read says to be sure the cat gets plenty of iodine, but the Science Diet YD food has less iodine. A human with HyperT is not to eat high iodine foods & people with lowT is to have more iodine. I'm really confused. Does anyone know for sure whether HT should have more or less iodine? I would like to get my kitty on the right food. thanks.
