I managed to get him to swallow 4ccs of the food, so I don't have to feed him again for a bit. He's still not moving, but has fine motor control of his legs. Whenever I try to place him vertically, he just slumps back over to the side. This leads me to believe he has a problem balancing, which could have resulted because of the head trauma he received.
He was given an anti inflammatory medication, so hopefully any concussion swelling will go down.
He is fully alert, but breathing hard. His enlarged liver pushes against the air sacs, making breathing difficult. Another reason as to why he might not be walking is because of abdominal pain.
