One of my four Hyper-T is having a thyroidectomy Saturday...he lost his left lobe a year ago...and it came back suddenly two weeks ago with a vengence...the right has to go...pretty sure we have a good parathyroid on the left and will try to preserve the right...

What I need is advice on supplementation after the surgery...anyone have experience with post surgerical cats? He needed absolute no supplementation after the first even though his right lobe was so atrophied that it was invisible to the naked eye.

Actually I fed him raw Sunday night at my son's house where he lives and the cat ate it ravenously but left a few morsels on the plate, then was able to settle for the first time in a week, quieted, stopped the frantic pacing and crying and trying to devour everything in site....seemed satiated...went upstairs, laid down on the carpet on his back, belly up in the imitation of your best Serengeti lion and fell asleep for the entire Super Bowl. My son said it was the first time he's seen him at rest in an entire week. Amazing...

I left him enough raw for the rest of this week and we put him on atenolol till the surgery (he is allergic to methimazole).

He'd lost two pounds in less then 10 days and all the furr down his spine...talk about sudden onset Hyper-T.

If you take the meds away...and keep him on the food...you will find a bigger surprise...there's a few curious veterinarians that are holding their endorsements for fear of doing a 180 deg. that cats can eat mice and doing very well on them as a food source....ST. Francis sez " r u kidding me BRO???"...

He's not on meds for his hyper-T although I tried hyper jia bing (Chinese herb)(works about half the time)...he can't take them...allergic...he's on atenolol because his heart is about to explode. I saw his other thyroid gland...it was the size of beagle's testicle and mottled with angry red tumors...very ugly. Histo said it was benign...your run of the mill ordinary hyper-t cat thyroid tumors. Unbelievable...if people could only see what they look like!

I'd like to defer to Doc. H...Bard Sacco is the second...but high protein solves many, many ...issues...treating the symptom is one thing...addressing the problem is a whole different issue...food and the right food is the source of the problem

Pat, why surgery instead of I131?

You may be right, my one and only son I learned was very free with canned human tuna and salmon in Oberon's diet. So free, it is a miracle the cat did not have steatitis. His previous duty in Texas and Louisiana as a stud muffin was, of course out of my control but I am sure he ate dry primarily....quality dry, but dry.

I am of the opinion that the rampant hyper-T seen in cats is due to an environmental contaminant and possibly a genetic predisposition. In my experience, I have often noticed it runing in households...clients tend to have multiples or successions of hyper-Ts (I have now had 6 total...4 currently). My vet has never had any. My cats are related...I don't know that the clients cats necessarily were...some might have been. I don't think anyone has done the studies...someone should.

yes Pat, why choose surgery over RAI?? it's soooo invasive & there are so many complications... bleeding, infection, loss of para-thyroid, damage to laryngeal nerves... although with some cats that may not be a problem
I-131 is relatively easy, time consuming, but sooo easy, & the problem is solved without those nasty side effects.
do tell.........


ETA: you don't need to give thyroxine after RAI as the cat then becomes euthyroid

Cost initially -- my boss is my vet--and the cat was unilateral originally...surgery seemed curative, the right approach, no travel, no overnights. He did very well with it...recovered immediately, amazingly fast and went home same day, and as I said needed no thyroid or calcium supplementation. We were very pleased.

Then a year later within less than a few weeks it had all gone to hell in a handbag again and you cannot even recognize him. He has the most aggressive form of Hyper-T I have ever seen...really. He's only 8 years old.

So surgery again, cost effective management for me...and my son. I have 11 cats to take care of and currently only one of them does not have a chronic disease. Believe me, I-131 would be my treatment of choice this time around, but with the agressiveness of this guys cancer...I bet I'd be back in six years or less for another go round.

Pat, if it's thyroid cancer then you need RAI to be sure it's gone. that's the only way you can be sure of a cure, & thyroid Ca is completely curable by this means. it's worth the $$, trust me, been there, done that.............S

Stephanie,

That's why I had the biopsy last time and it was benign...so presumptively I'm dealing with the same animal this time too. At any rate...do you have some idea what my supplement for him in thyroxine should be because I have no clue...this is our first bilateral thyroidectomy. Start low and start when? I can do my research, but I thought I'd see if anyone here had the experience because books aren't always the be all-end all in this department I've found.

Pat

I think you'd have to check his levels & see if there are any then dose accordingly. start low then keep checking every couple of weeks until you hit the right dose. start at maybe 25mcgs?????
check that with your vet..............S

So they don't metabolize it as rapidly as dogs...that's about 1/4 the comparable dog dose per weight?

Update on thyroidectomy...intubated and ready preping cat but could not palpate thyroid gland...ANYWHERE...we decided to scrub the surgery...since the last time we were in the gland was not there...our belief is that its in the thoracic cavity. His T4 is over 9 and his Free T-4 is over 100. Cat is 10 years old.

Any recommendations for a clinic in the Bay Area or central Florida...I've found some on the web. I know several of you have had experience with several of the clinics already.

Florida Vet Specialists, 3000 Busch Lake Blvd, Tampa 33614 813-933-8944

I've used them twice now, and like them. It's a huge, state-of-the-art specialty clinic. They do not do the technitium scan, but they are only $1100 and only keep the cat for two days. Dr Erick Mears is head of the IM dept. If your vet calls the cat his own, they might extend a professional discount.

AVS is here in Orlando. They do the scan, but the cost total is almost $2000 and they keep the cat for 1 week. Let me know if you would rather have their info.

Barb, thanks...that's who I was leaning towards...my vet recommended them too...I think I'll go down drop Oberon off and go repair irrigation hoses for those 'non existant orange trees' for two or three days and pick him up and come home...kill two birds with one stone...thanks so much for the info.

Pat, call and make an appt - they do intake on Mon and pickup on Wed. Remember that anything you take for him to sleep on will not be returned. Most of us donate an old tee shirt we've worn, so has our smell on it, so that he has something to make him more comfortable. They will also feed whatever you want, including any food you take them, raw included.

They will do an US on his heart, as well as lab work to check his kidneys. They do not require a tapazole test.

That's good since he is off tapazole (highly allergic to it). He is, however, on hyper jia bing and I don't know whether to keep him on it or remove him...it may be starting to have an effect? The herbal remedy does take longer to 'kick in' which is why we have continued to give it to him daily.

It would be neat if they do scintigraphy as part of it? Cause I really think its down in his chest. Thanks for the information. I will call them tomorrow and see if I can set it up.
