My 15 year old, Hestia, has had hyperthyroid for several years now that we were treating with Methimazole tablets. Recently she's been vomiting quite often and we added 1/4 tab Pepcid AC twice a day to the regimen. Still vomiting so we switched to the transdermal ear gel of the medication and continued the Pepcid. Still vomiting. I notice the liquid in it is bright yellow which makes me think bile. I'm waiting a few days to see if this continues before I call the vet again and see what's next but anyone have any experience with a hyperthyroid kitty that just won't stop vomiting? I've tried different foods and it doesn't matter. She's actually on Iams Digestive kibble right now bc when I give her canned food she actually vomits MORE. I'm not sure if there's something I'm overlooking. I'm starting to wonder if this will just never stop or if something else is going on. Any help would be appreciated. She just had a check up a few weeks ago with full on complete senior blood panel and nothing else was indicated. I wonder if I should ask for an xray or ultrasound or something...
