I guess 5 years is long enough for a little complacency. I know she just ate recently, and then promptly went into shed. Went in to check on everyone, and she was laying on her side, looking bloated and lumpy, and very still. I couldn't even see the motion that you usually see when they breathe. When I tapped the glass, she didn't move, not even a tongue flicker, and I began to worry. Opened the sliding door, and she was still unresponsive. Usually at least turns her head, or flicks her tongue when her door is opened. Poked her, to make sure she wasn't dead (paranoid, I know) BAM.
