Update: This is a true enigma. Just now back from the vet and she can't find anything wrong with him aside from the heavy breathing. No infections, his airway is clear, X-rays were normal, and all his organs looked to be the right size and in the right place. Her best guess was he essentially bruised or pulled something in his aggressive feeding response. Going to leave him alone for another week or two and just monitor his condition. She says she will consult with some other docs to see if they have any other ideas.

On the bright side. He is able to lay loosely coiled now. He's not been able to do that comfortabley since this started. He would try, and then lay straight again a min or two later. Hopefully this will clear its self up in a few days.
