Thank you all so much for your words of encouragement, advice, thoughts and prayers. Max is still with me.
I sat up all night with him, helped him on and off the sofa, to the water bowl, to the litter box, back to the sofa...aaaaand repeat every 15 to 30 minutes all night long. We both did sleep from 3-4 a.m. but that was it. More a/d by syringe this morning, 1.75 units at 9:50 a.m. BG 596.
Took him to the vet at noon, and I feared it was going to be his final trip. Lots of tears. But. She checked him over, had vet tech give 150 ml fluids, drew blood for testing, talked strategy and sent me on my way. With Max. A cautious "yay"! His BG was 462 at 1 p.m. I'll continue to offer him a variety of food but syringe feed him small amounts of a/d throughout the rest of the day and evening. Next shot due at 9:50 p.m. and we'll do 2.5 units.
Blood work back by end of day so we'll see if he's got kidney failure. I have to give another 150 ml fluids at 4:30 p.m. She gave me a better syringe (bigger) to get the a/d in him (I was using a little 1/2 ml thing, all I had on hand last night), and he voluntarily drank human tuna juice and nibbled a few, tiny pieces when we got home--which is more than he was doing last night and early this morning. We're adding fluids every 1-2 days to our routine. He hates it but he'll feel so much better...and hopefully, more willing to eat. He's so dehydrated that they had a real problem drawing his blood. Had to take it from his inside thigh which upset him terribly, took a long time, and wore him out.
Whew! Sorry for the long post. Please keep thinking good thoughts for Max. He's not in the clear, but we both feel better. And again, thank you. With all of the anger, harsh words, and unwillingness to listen and compromise in the world today, you are a refuge of caring and kindness not only to your own special kitties but also to kitty strangers and their loving beans.
