Hi, I can help you with your question today. Do you think she is drinking more than usual?
Ok, there are many different conditions which could cause her to stop eating like this. They include pancreatitis, kidney disease, and diabetes mellitus (most animals start by eating more than usual, but can progress to anorexia if they become ketoacidotic).
I recommend having her evaluated by your regular vet tomorrow. I would start with a physical exam and blood work to check her major organ function including her pancreas. Hopefully these will be enough to get a diagnosis so that we can begin a targeted treatment plan for her.
Once we have the lab samples, your vet can also prescribe an appetite stimulant called mirtazapine to help her eat and get nutrition while we wait for the results of her tests.
Please let me know if you have further questions. I am happy to continue until I provide the service that you seek.
