Update- He is doing much better. Eating, playing, chirping, and he likes to rub against my hand and nip at me? Its super cute. He has already clearly put on weight so now he isn't just skin and bones. In addition, he is barely spending any time in his cave like he used to, now he likes to be out and about and bathe in the warmth of my desk lamp.
