This is a quite generic but concerning presentation. Differentials are many, from gastrointestinal diseases (infection/inflammations often dietary related) to any disease that can spread systemically (causing lethargy for example) like infection, and anything that can cause pain/discomfort. The approach must be logic, starting from offering different kind of food. A check up is needed if inappetence lasts for more than 24hours.
