Hello Kyla:
I have some questions for you:
Awaiting your reply.
Thanks for the quick response.
When older cats begin to have both bowel and urinary accidents it is usually a sign that something is going on internally. It could be a urinary tract infection, kidney disease, hyperthyroidism, cognitive dysfunction (senility), or cancer.
I recommend getting her into your veterinarian for bloodwork to see what's going on with her and give you a better idea as to her prognosis. Older cats have a tendency towards kidney problems, but these can usually be managed with a diet change after supportive care. Kidney disease can result in all of the signs discussed.
Let me know if I can answer anymore questions.
