Update

He made it through the night...

and now, as the vet put it, it's a "waiting game" to see if he pulls through the rest of it.
He came through surgery o.k. and he's currently on 2 antibiotics specifically for his liver and is, thus far, responding well to being fed through the tube.
He's being fed every 3 hours and they will keep him in intensive care throughout his stay with them.
Tonight J and I will go visit him to check in and see how he's doing.
I don't know that I won't have a big reaction when I see him...
I think back to when we went to go see him the night after his neuter/declaw/dental work and it tore me up to see his legs wrapped and that he was so out of it and sad looking.
Yesterday the vet had to about tear him away from me - he was so tightly curled and closely clinging that it killed me to have to be separated from him...and he had this sad look on his face as he was taken out of the room.
* sigh *
I'm sure I'll update tonight after my visit.
But that's where he's at as of now...
