My hedgie has gotten out a couple times (mainly in the past couple of days - once they get it in their head that they want to escape, they just dont stop trying...), and it was in the middle of the night, and he had squeezed under my door, went into my parents room, and I dont know where he was in there but he woke my mom up and she was REALLY mad at me in the morning, and threatened to get rid of him
but luckily I've fixed the problem so theres no way he can get out now! =D
