I put my two garters down for brumation a while ago; however, after I re-inspected them, I decided it would be best if I took them out early. I did this on account of Bizet in particular because he wasn't eating regularly during the summer.

Anyhow, Wagner came out of brumation and started eating (like a pig) nearly three weeks ago. Bizet hasn't started eating yet at all. He is also very lethargic. Is it possible that his body is on a schedule and he won't emerge from brumation, regardless of the warmer temperature? Is there anything I can do to bring him out?

Thank you!
