My sweet G.luii had gone very sick. I don't feed him every day (night), but 2 days ago he wouldn't eat and hasn't been eating since. Today he is all sleepy and don't want to move at all. When I took him up he just laid in my hand, not moving at all.

I've had him for about a year and before that friends of me had him for almost a year and it has never been a problem.

He had some trouble shedding when he lived with my friends but the last year he's been doing it trouble free. Last week was the last time he did it.

Please help! What could it be and what can I do?
