I took Onyx to the vet yesterday. He has lost some weight lately. I think he's been loosing for awhile, but it just hit that noticeable stage. He's double coated and long haired so he looks bigger than he is. Last time he was at the vet, Onyx weighed just over 18 pounds(that was quite awhile ago). Yesterday he weighed just over 11 pounds. So the vet, Dr. Helen, ran every blood test known to felines!
She just called with the results. Onyx's T-4 levels are borderline high and his one of kidney enzyemes are elevated. I have to drop him off tomorrow morning so they can run a urine test to see if his kidneys are concentrating properly. If they aren't, we'll run into the same problem I had with Beau--treat the hyper-t and make the kidneys worse; treat the kidneys and make the hyper-t worse. Fortunately(?), Onyx is only 6 so he's a much better candidate for any kind of treatment than ol' Beau. He would have to fly to Vancouver if he needs the radioactive iodine treatment.
