Re: [Felvtalk] Hyper thyroid in cats

[Amani Oakley]

Hi dlgegg

I confess to not having had to deal with this yet in my cats. However, I did 
some research for you and see a few things that might be of interest to you.

First, the radioactive treatment should not have resulted in any nasal 
bleeding. I couldn’t find that commonly described as a side-effect of the 
treatment. Perhaps things have improved with the treatment since you last used 
it on your other cat, ten years ago, and you could maybe ask the vet about 
that. It is correct that there is a period where the cat has to remain at the 
vets, until the radioactive levels subside but that seems to be described as a 
week or so. This treatment is considered permanent, and would then not require 
ongoing medication.

However, one thing you might want to explore is getting CBD Oil and trying 
that. Certain strains are found to be very good for hyperthyroidism, and there 
are no side-effects. I am not sure which state you are in, and whether CBD Oil 
is legal in the state you are in. It should be as it contains no THC levels at 
all, but governments have been stupid and schizophrenic about such things. Look 
up “Medical Marijuana and Hyperthyroidism” and see what comes up. The articles 
you will see relate to use of CBD for hyperthyroidism in people, but you can 
get CBD Oil for animals as well.

Hello everyoone,
I have a 12 year old former feral who was diagnosed with hyper thyroid 
yesterday.  Herm level is 4.7 and she is one meds, 2.5mg of Felimazole morning 
and evening.  I had one cat about 10 years ago that we did radioactive iodine.  
the isolation was very hard on her and she went downhill after she got home, 
bleeeding from nose, etc.  don't really want to repeat that.  Homey is 
especially bonded with me and has been my caregiver since my heart surgery.  
she has alerted me to one time of gasping for air in the night and 3 instances 
of low sugar.  she sleeps plastered to my chest and when she is on my lap, 
holds on to me .  I am very attached to her and do not want to loose her so am 
hoping meds work.
my question is:  does anyone know of alternative or better ways of treating 
this?

Hello,

We have taken numerous cats to Radiocat for iodine-131 treatment -- at least 10 
-- in the past 15-20 years. In spite of our mostly good experiences with I-131, 
I would think hard before putting a FeLV cat through it. If the Felimazole is 
working, I would be inclined to continue with it. 

But if you do want to try I-131 therapy, I would first have a FeLV ‘viral load’ 
test run. Scanelis in France offers it. I can pass along the info your vet 
would need to draw the blood Scanelis would need to run the test. They are in 
the south of France, near Toulouse, and do speak English of course, so 
communicating is just fine. The cost was about (USD) $109 plus shipping, about 
$200 altogether.

It’s unfortunate that no US company runs a similar test, not even the older 
cd4:c8 ratio that I found useful. Sigh.

 

Best regards,

Lorraine

could be used along with the Felimazole, as it would not likely have any

Re: [Felvtalk] Hyper thyroid in cats

[Lorraine Johnston]

As this group is FeLVtalk, I assumed that cats discussed here are FeLV-positive 
unless the writer says otherwise.  

 

Yes, I would indeed hesitate to put a FeLV cat through I-131 therapy. We’ve 
seen many of our rescues go temporarily hypothyroid (ie, underactive thyroid) 
for 2 or more months as the treatment, after it is administered, gradually 
kills the overactive thyroid nodules and the healthy thyroid tissue has to wake 
back up. This happening is known to veterinarians administering I-131 and is 
one reason they recommend waiting to test the thyroid until 60 days after 
treatment.

 

Sometimes, though, the cat’s thyroid becomes oversuppressed because too much 
tissue was destroyed, and the cat needs supplementation with thyroid hormone. 
In two of our cases, permanent supplementation became necessary. 

 

This is meaningful to FeLV (and FIV) cats because when the thyroid gland is 
working too slowly, the immune system can also slow down. This has been seen in 
humans and in dogs, so I suspect cats would be affected as well.  So, for my 
own FIV cat and for my cousin’s FeLV kitty who we baby-sit, I wouldn’t use 
I-131 therapy without thinking hard about it, especially if the cat is doing 
well on methimazole.

 

 

Hope this helps,
