My Boo was recently diagnosed as hyperthyroid, now he's hypo and off meds for the time being. However, the med itself is very inexpensive. I can look up the receipt, if you like, to give you an exact amount but I can recall that it isn't expensive at all. My vet, though, feels that the gel for inside the ear isn't very effective. I hope I'm not speaking out of turn here; just telling you what he said. He told me that would be his last resort if a cat won't swallow the meds. Good luck w/Stormy and please keep us posted. This is such a tricky disease.
