Batman likely does not feel good and could even be in pain. Just like people, there are many conditions that can make pets feel sick. This could range from bacterial over growth to intestinal blockage. Also like us, diseases are best addressed early and this may result in a better prognosis. I recommend to have him examined by the veterinarian today. The doctor will need to learn the underlying cause in order to give appropriate treatment. Bring in a stool sample in case the doctor needs to test it. Batman could even have something like a broken bone or a back injury. I hope Batman starts feeling better quickly! Please feel free to post any additional questions!

Poor Batman. I suspect that he is sick if he won't eat anything and is lethargic. Not eating and lethargy are both signs of illness. I'm quite concerned about him, and thinks he needs to see a vet now. Please take him into an ER vet clinic; if there isn't one in your area, there will be a vet on call for emergencies. The information to reach that vet is found on a clinic's answering machine or website.
