Sleeping in doorways

originally uploaded by e³°°°.

So, for the last couple nights, Mouse has taken to waking up in the middle of the night, padding over to our closed bedroom door, and lying down in front of it. She just falls asleep right there with her face by the crack under the door and sleeps. I tried putting a comforter down for her so she wouldn't be lying on the bare wood, but that just meant she had bring the comforter back to the bed before going and lying on the wood floor again. I am beyond confused. Maybe she's imitating the dog? She wants a firmer mattress? We're just too stinky and she needs fresh air?
