So the fist few days at home did not go completely smoothly, with Chandler getting a bit agitated toward the end in the morning sessions, and falling asleep in the evening sessions, but I think I have figured out the right combination. The magic bullet seems to be to set him up with a bowl of chips, yummy enough to keep him happy, crunchy enough to keep him awake.
I am also adjusting the set up a bit, I will take a picture of it tomorrow so you can see it.
Chandler is eating like a horse. He has been such a picky eater and was a bit on the small side, but he is starting to plump a bit. I dunno if it is the light or what, but he is constantly asking for food and eating things that he wouldn't have before this treatment started.
