Toothless has started...going to bed early.? We turn the lights on/off at 10 am/pm and he usually would start finding somewhere to burrow/cuddle at about 9 but here the last several weeks, it's been as early as 6, but usually between 6 and 7. Is that normal.? He eats (slowed down a bit due to winter) normal, basks normal, poops normal and runs around and is active, for the most part. I know they go to bed when the sun goes down in the wild but I just wanted to make sure this early bed time is normal for them.
