This is a quite generic but concerning sign. 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 usually if inappetence last for more than 24hours (so a check up is required now basically..). Please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.
