She's done that. She's been restless today, and I just made sure everything was spotless and misted her, so she's been moved just before I took the photo. She didn't approve, and gave me a hiss (normally is just a sweetie). I'm thinking the restlessness is pre-lay behavior.

The past couple of days, she's been twisting like crazy, found her in some of the strangest positions when I've checked on her--upside-down is only the half of it, lol. ^_^ So, I think she's been moving them down.
