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