I got some w/d from the vet, but until today he wouldn't touch it. I was more concerned with getting him to eat anything at all. His appetite is definitely coming back! He has eaten what I would call his normal level today - including the w/d! We are still waiting patiently for the results of the Cushing's tests. I hope his appetite stays good, upping the insulin has helped. When I talked to the vet today he said we'd probably have to up it again, but for now I'm ecstatic.
