Cuddles is definitely about to shed for the first time. His eyes are that blue, cloudy color. He's also been hiding for almost two days straight and he's refusing food.

I don't really know what to do and what to watch for, and I'm worried because I'm leaving in a few hours and I will be gone the rest of today, all night, and then part of tomorrow, and I definitely can't take him with me. Will he be alright until tomorrow?
(He had to choose now for his first shed! Ugh.)

What should I watch for that would be indicative of something wrong? How long should it take for him to shed?
