Sick cat - 16 years old.?

first, congratulations on being a good pet owner and doing what is right for your cat. i'm glad you have also found a vet that actually did an biopsy (aspiration). it very well could be the thyroid medicine- it maybe that you will have to find something different to use, or opt for surgery or radioactive iodine (most don't do the iodine). there is a possibility that your cat does have lymphoma (in animals lymphosarcoma is what it is usually called). if so you know you can treat her for a while before having to make a decision. i would not do any type of chemo, all chemo treatments i have seen in animals have been negative. you can however, treat her with prednisone or dexamethasone both are anti-inflammatories and will help slow the growth of the lymphoma for a time, after a while nothing will help and you will have to make a decision.

good luck

edit: sometimes in pets if there is a problem with medications you can stop the medication for a few days and restart it with no problems, but of course if problems persist then you will need to find a different medication or alternative.

My older cat- who was also 16- was put on thyroid medicine. Although allergic reactions only occur in something like 5 to 10 percent of cases, my cat was allergic. Her symptoms for the first few days sound like what your cat is going through. After a few more days she also developed itchy spots (her skin would ripple) and her feet must have felt funny to her because she started shaking them like a cat would do if it stepped in something wet. She moved into the front closet and wouldn't come out. Did not have swollen lymph nodes though -reactions can vary. I hope your news is good.

I took my cat off the thyroid meds obviously.

Every cat I have had that lived past 16 started getting vocal at about 15, especially at night. A mild sedative helped with this.

It is hard to part with the animals we love.

My last cat, Scat, was 17 years old, was still eating, but had massive bowel movements, and kept getting thinner.

It was the first time I learned to not be selfish, and think about the quality of life for my beloved cat.

The reason she might be hiding is, that most often, cats go off somewhere quiet to die.

Wait for the results, if they want to continue many more tests, think about the stress to your cat.

I also found a man to come to my home to Euthanize my cat, as it was quite expensive, I did not want to put more stress on Scat by taking him to the vet to die.

He died quietly in our home.

It was so hard, but I know it was the right thing.

You are doing so much more than most do for their cat,

So hang in there!

Best of wishes.

there are 2 types of medicaion for Thyroid (and i cant for the life of me remember the names)

One is an orange tablet the other a white one, one of them is known to sometimes make the cat vomit (i am sorry my brain wont work tonight).

However, the fact that she has swollen lymph nodes might mean there is something else going on.....I hope she is ok xx

i no it sounds mean but she is a very old cat so be prepared if something happens to her. sorry to hear about her sickness i hope she gets better.

she might be to old sorry
