My male cat seems to be breathing heavy and lately he’s been really aggressive and doesn’t let my family near his abdomen.. What could be wrong?

Hi, and thanks for your question. 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. A check up is needed if this presentation lasts for more than 24hours. Hope this answer was helpful, but 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. Please find the time to give us a feedback about the consultation as that will be used to improve our service.
