Rozzy's news is not all bad. Her thyroid levels are out of whack and her kidneys are beginning to show disease. When we get her thyroid back on track it could make her kidneys worse. Yet, she's not had any accidents in a few days.
For now we keep her comfortable, work on her thyroid issues and monitor her kidney function. (for the record she has had thyroid issues for about 2 years, the kidney disease is new)
Thank you all for your kind sage advice. I was relieved she is not diabetic. I would not have treated her at nearly 18 for diabetes.
I won't prolong things when her kidneys worsen, but for now we can love her and keep taking her to the box a few times a day.
