Ask the Vet About Hyperthyroidism in Cats

I have a prescription from my vet & I’m wondering how to get the information to you.

My cat was estimated to be 6 years old when I adopted him from a shelter and shortly afterwards he was diagnosed with hyperthyroidism. He's now 11 years old. We tried methimazole first but he would vomit it up shortly after administering it. Vet switched him over to Hill's prescription diet dry food y/d which worked for a while but with vomiting that worsened over time. The whole time he had very loose, watery stools. Switched to the Hill's y/d can food. The vomiting slowed for a while then became more frequent again. Stools continued to be loose. It was getting so bad that he was sick daily. He'd howl and vomit, and try unsuccessfully to make it to his litterbox. I could tell he was in pain and distress. I suspect he has IBD as well. He has gone from a healthy 12 lbs when I adopted him, to less than 8 lbs. He is so skinny his bones are protruding, and he sleeps all the time. My last desperate attempt to help him was to give him a raw food diet consising of organic chicken thighs, hearts, liver, and supplements recommended by a holistic vet. He did amazingly well at first. Solid stools, no more vomiting, and became playful and energetic. Sadly, this only lasted about a week. It's been 3 days now and he hasn't eaten. I'm out of ideas and cannot afford the radiodine treatment that could potentially cure him. I guess I need to know when it's time for me to let him go - to have him euthanized.

I accidentally gave my one cat the other cats felimazole, 2.5mg dose. She seems ok. What should I watch for?

What are the symptoms of a thyroid problem in cats?

Is there a transdermal compound that would deliver 2.5mg of Methimazole 2X per day? What would be the cost of a 30 day supply? This is for a 15 year old female cat. Thank you!

Seeking a second opinion, going to try to keep this brief! My 14-year-old cat Budder has hyperthyroidism and severe anxiety — he shakes, howls, etc. while being transported, in unfamiliar environments and around unfamiliar people. Tomorrow we plan on taking him to a friend’s house for a few hours while things are done in our apartment, but it seems likely that he has high blood pressure and I’m worried that the stress of transporting him + the new environment could cause a stroke or a heart attack. He started transdermal Methimazole last week after months of inconsistent treatment with tablets throughout which time he continued to show symptoms of hyperthyroidism. We’re still waiting for the results of urinalysis and bloodwork so we ultimately don’t know anything about the state of his heart and kidneys. We have Gabapentin that he was prescribed some time ago, before his hyperthyroidism diagnosis but some time after the onset of symptoms. He was still very stressed the last time he took it but it definitely helped and there were no complications. I realize this may be too much to ask of someone who has not examined him, but is Gabapentin more likely to help or harm in this scenario? Are there other medication options we should be exploring (ex: blood thinners, etc.)? Should we postpone the work in our apartment until we have all of his results back? Again, my biggest concern is the stress causing his blood pressure to sky rocket, causing a stroke or something of that nature. I can’t overstate the severity of his anxiety. He basically has panic attacks. Finally, if he does in fact have high blood pressure or a heart condition, what is the likelihood of extreme stress causing a medical emergency? Apologies for the many questions, just want to make sure I’m doing the right thing for him. Thank you.

My cat is showing many signs of a thyroid condition..sudden ravenous appetite..matted fur..weight loss..could this be the problem?

Do you have a medication called ( Methimazole) 50mglml transdermal gel if so what is the cost and do you take CareCredit MasterCard thank you Kathy

My 12 year old cat has been on Methimazole (1/2 pill 2 x day) for almost a year and has been doing great on it. Before being diagnosed she had what we thought was a seizure. None since being on the meds until today. is there any connection?

Is kenalog safe to give cats with hyperthyroidism?

My cat is a very picky eater. She only eats pate but is not consistent in what flavor or brand she will accept for that meal. She walks around howling for food 24 hours a day but only eats a few bites and walks away. I crush Methimazole tablets in food but 95% of time won't eat it.

My cat is a 9 year old feline, she has suddenly developed a various appetite but has not gained any weight, we took to her to the vet he ran a lot of tests and found nothing wrong. Could their be a reason why she l suddenly in creased her appetite. Thank You Valerie

I currently give our cat 1/2 a pill twice a day of 5mg Methimazole. We will be away and I?m trying to figure out an easier way for someone else to give my cat her medicine. Is the compound a liquid I squirt in her mouth or put on her food? Is it better than the transdermal? Thank you

What do you recommend as the BEST FOOD for her situation. New rescue, way underweight, shabby appearance

My cat is taking a pill daily for hyperthyroidism. We are planning a vacation and will not be able to take our cat with us. Is it ok to skip the pill for 10 days? She has been on the med for about 1.5 months and we do not have anyone that can give it to her daily or afford to board her. This may be a determining factor if we can go on vacation. Also, she has responded well to the pill and is gaining weight and acting normal. Not sick or acting strange.
