We went on a week long vacation and left our kitty at home like we always do as she was always happy there. I had someone check on her since we had never left her that long. They called 2 days before we were coming home and said they found the cat dead on our bedroom floor. She never had any real known problems. The week before she was drinking more water than normal but that had quit by the time we left. I made a note to myself to watch for that when we got back and I would take her to the vets. I am so heart broken that I left her and was not here when she needed me. My husband says it could have happened any day while we were at work. She was eating up until the last day. She was 9.
