I read if the temps don't go below 70-75 at night, we don't need heat at night. So as the weather got warmer I haven't turned on his CHE at night. My daughter apparently hasn't realized this yet and this am when she woke up she yelled out that Fury's heat wasn't on last night and he is was dark and cold! I read his temps real quick and it was 75 on both sides. He was cold and darkish so we turned on his heat lamp. We always turn it on right away upon awakening anyway. He was very light last night while sleeping. He is 15 inches and 7 mons old. My question is should we turn the CHE back on at night or is he fine even though he's dark when he wakes up?
