Good news! I still have to wonder if her eyesight is going which could explain getting up during the day. She's only sleeping at night? I have had some who still had good eyesight that got up during the day. I always thought that maybe like us their bladder weakens as they age and "Hey, while I'm up I might as well have a bite to eat.". But they often got up to eat/potty during the evening hours too.
