Hi, we just got our first hamster Oreo a few days ago and have the Omlet cage. He’s made his nest in the cardboard multi chamber hide and has only been out at night when it’s dark so far. I think he’s gradually settling in though and getting used to the sound of our voices. My question is about cleaning the nest. Do I just leave it alone for a week or two? I can’t see in there at all unless I lift it up and disturb the area. I’m worried I scare him (even though I would only consider checking when he’s awake) but equally not sure if it’s clean inside.
