Orange is driving me crazy.  He's warmed, but not really eating.  He's more into the Pedialyte than milk.  He's barely eaten, and I've had him since 4, so he should be hungry.  He gets fussy when I pick him up, and he falls asleep really easily.  If I pinch him, his skin goes back right away, so I don't think he's dehydrated.  If he can make it through the night, he'll see a doctor.  I'm hoping he hangs on, but I'm starting think he may not.  🙁

I found a random maggot... it was not on him, but on his paper towel.  I have searched his whole body and see no other place it could come from besides his wound, which looks pretty well closed up.  I am not sure what to think at the moment.  🙁
