Hi Charlotte,
I am sorry your kitty is having trouble.
When blood was pulled for the thyroid test, did your vet also run a comprehensive blood panel?
Were other diagnostics run (urinalysis, E.R.D., radiographs)?
Did your vet want to hospitalize your kitty and put him on i.v. fluids?
Is he eating at all? Is he jaundiced (yellow skin, eyes, ears)?
Let me know and I will try to help you
Charlotte,
Thanks for the additional information. I am EXTREMELY concerned about your kitty, and he definitely needs to see the vet again and cannot wait until tomorrow. White gums indicate that he may be bleeding somewhere, possibly into his abdomen. He may have a mass on his spleen that has ruptured, or he may have masses on other organs. I know you don't want to put him to sleep, but letting him linger and suffer at home is not the better choice. He definitely needs hospitalization, and full bloodwork as well as radiographs. He may need surgery, and almost certainly will require multiple blood transfusions. He will require constant 24 hour intensive care, so an emergency clinic is going to be your best bet. He may have many years of quality life ahead of him if you get him seen and treated NOW. The longer he goes without medical attention, the more decompensated he will become, and the more expensive it will be to make him healthy again, if that is even possible at this point. I am afraid that he is going to die very soon, and neither one of you should have to go through that.
Please, please take him in to a vet tonight. Hopefully you will have some treatment options available that you are able to have done. Please let me know if I can be of further assistance. If this has been helpful, please hit the green accept button. Best of luck with your kitty.
