I had my ball python out on the ground and she crawled under a blanket on the ground. I thought she would reappear but she didn't and now she is gone. (This happened yesterday.)

There is no gap under the door so she would not be able to slither out. There is a gap under the closet door.

I am afraid she went into the heater, but I do not see her. (It is difficult to search inside the heater, but I have opened the front panel.) I am not sure if I hear her slithering or it is just air moving. I am going to remove the duct cover to be sure, but I do not think there is a hole, it just covers pipes that go through the wall.

I have systematically began moving things out of my room. (Like very thoroughly looking in boxes, collapsing them. Throwing out old papers, nothing that a ball python could really hide inside.

She is kind of small (maybe 1.5 feet and 5 months old? I never measured her).

Can ball pythons get stuck? I thought she would reappear since it is her feeding day and she is not old enough to have that much fat stored. The only place I can think of is the heater.

Also do they end up inside trash cans? The only thing I threw out without checking was the trash, but I think I would have heard the crinkly bag sound if she went near the trash can.

I really want to find her because I am moving out in a month.
