Guilty human feels guilty

When I got up this morning I found Dymphna on the stair down from the kitchen into the laundry room. Lying on her back. She'd been there a while, as she'd peed while she was lying there. I got her picked up, and she spent the rest of the day wandering around the house, keeping an eye on me as I picked things up and tidied. Then while I was putting clean sheets on the bed, I felt my foot hit a solid object just under the bed, and she squealed. Poor Dymphna. I don't know where she's gotten to now, either.
