Topic: hyperthyroidism and extreme stress
vet-qa-signature

Question: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.

Answer:All of these questions are going to be best answered by his veterinarian who has access to his bloodwork. I would wait on that to come back to see if the gabapentin is ok to give him, so yes, it sounds like it's best to postpone if that is an option, until his bloodwork comes back, then ask your veterinarian. That will give the methimazole patch a little longer to hopefully get him more regulated as well.

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

Answer:Yes, hyperthyroidism is fairly common. Many other conditions can mimic it (especially the weight loss and unkept hair coat) so see your veterinarian for some quick & easy blood tests to see exactly what is going on.

Topic: Hyperthyroidism and seizure connection?
vet-qa-signature

Question: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?

Answer:Seizures are not a common clinical sign with hyperthyroidism, but it is certainly possible as the thyroid gland affects the entire body and since the medication to regulate her seems to help.

Question:Is kenalog safe to give cats with hyperthyroidism?

Answer:It is not necessarily contraindicated, but I would really need to see your cat's blood work and know exactly what medications s/he is on to know whether it was ideal for your cat so consult your veterinarian for the best advice.

Question: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

Answer:Hyperthyroidism is a possibility - this wouldn't show up on routine blood work (CBC/profile) so ask your veterinarian about this if he continues to eat so much and/or if he starts to lose weight.

Question: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

Answer:You can get chewable, liquid or transdermal. I prefer the chewable or liquid - I just have better success regulating my patients but, of course, it needs to be swallowed. Here is a link that shows the different compounding options: https://www.1800petmeds.com/Methimazole+Compounded+-prod90110.html

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

Answer:Getting her hyperthyroidism under control is more important that the kind of food she eats - really just any high quality food for senior cats. There is so much competition in pet food nowadays, our pets eat much healthier than we do, for sure, so there are many options. The big 4 food companies police each other so carefully, I lean toward their food because I know it has been heavily scrutinized: Royal Canin, Science Diet, Purina, and Blue Buffalo.

Topic: Going on vacation....giving meds
vet-qa-signature

Question: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.

Answer:Your veterinarian is definitely the best one to ask because s/he has access to her blood work (and her) so knows the severity of your case better. Missing 10 days is not ideal though, in general.

Topic: Side effects of Methimazole

Question:Is it normal for a cat to vomit frequently from the condition or medication? And do they somewhat drool at times?

Answer:I don't really know what you are asking exactly : frequent vomiting is never really normal. Hyperthyroid cats will vomit until they are well controlled. Methimazole usually doesn't cause vomiting.

Topic: What should I know?

Question:How did my cat get hyperthyroidism. He is on medication twice a day. Is there anything more I should do? He is on trans-dermal as he is very difficult to pill.

Answer:We don't know why some cats get it. The medication twice daily is usually all they need. Here is a good article about hyperthyroidism, written by another veterinarian, from a site that I trust: https://veterinarypartner.vin.com/default.aspx?pid=19239&id=4951398

Topic: Foul Smell

Question:I just began fostering an 8-year female cat with hyperthyroidism. She is currently taking methimazole and seems to be doing well. However, her coat is shabby and foul smelling. Is it ok to give her baths? Will this help and if so, how often should I do it? Will this go away on its own as she continues her treatment?

Answer:Contact your veterinarian for the best advice but is she is stabilized on her medication and doing well, eating well, it should be fine to bathe her. It may help but it will probably just be a matter of getting her underlying problems under control.

Question:I would like to purchase a supplement for Pumpkin due to his hyperthyroidism. He is doing well on Methimazole except he seems sluggish and frequently lays down after walking very far. I cannot give him power because I have many other cats and I free feed. His appetite is good and coat is good except that he occasionally rips out fur on his back. Pumpkin is an older cat, 8 years +. What would you recommend?

Answer:The first supplement I would try would be omega 3 fatty acids, like this product: https://www.1800petmeds.com/Super+Pure+Omega+3+-prod10910.html Opening the capsule and squeezing just a little on dry food is usually very palatable for cats since it is fish oil.
