Reply to Lori's Post: I waited until 2 a.m. for your reply then called the all night animal hospital and took him in, because by then he was "crouching" and looking just miserable. They thought, on the phone, that maybe he couldn't urinate. Turns out, $413 dollars later, that he has tonsilitis. BRIGHT red tonsil (lymph node) on the left side. He had a fever. So, he'd been hacking, trying to get the thing that hurt his throat out. Anyway, he was also dehydrated, so he got subcutaneous fluids and they left in the IV catheter, so our own vet could give him IV fluids today if he still needed them. Also he got antibiotics, although his white cell count was normal. He's been at our vet since 7:30 a.m. and we haven't heard anything else. The good news: he doesn't have feline leukemia or FIV, and his other blood work was all within normal limits. His lymphocytes were very low normal, thought, at the border of the low range.
So, right now, the diagnosis remains tonsilitis and dehydration. Don't know anything else.
