Thanks for all the good wishes. I read all of them, and even if I don't mention you by name, they all mean a lot!
Maxxy is home and he looks hungry

But they said not to feed him until tomorrow, so he's only getting little bits of water but he looks like he wants to eat. His eyes are glassy looking and his tail is down but otherwise, he's just watching us with big, brown, sad eyes

. Why do you think they wouldn't let him eat some soft food? Poor guy.
Nerak, you right, I need to wait on the results before worrying that he'll die. I guess it's normal to be this attached to a pet where you feel like it's a family member that's ill.
