When i got up day before yesterday i found my biggest tortoise upside down under his heat lamp,i don't know how long he'd been there but as he's fine now i'm guessing he wasn't there too long,but now i,m scared he's going to do it again in the night and i'll be too late to save him,so would blocking up the door to his hide harm him,because these sleepless nights are really starting to harm me lol
