Missy has to see a vet as soon as possible. When a cat doesn't eat for three days, they develop a fatty liver which is fatal without treatment. She needs to see a vet now to prevent that from happening. In a senior cat like Missy, her anorexia could be caused by kidney failure, cancer, diabetes, and liver failure among other causes. It's also serious that she hasn't used the litter box in two days. She needs a physical exam, geriatric blood panel, and urinalysis to diagnose what is causing her symptoms so she can be treated.
