Poor Tigs! It definitely sounds like something is wrong. Unfortunately, these are very vague symptoms that could be caused by almost any kind of medical problem - shaking, acting lethargic, and not eating are generally signs of pain or discomfort, but beyond that he would need an exam and some diagnostic testing to determine what's wrong. I would recommend taking him to the vet today to be seen. He/she can do blood work, x-rays, or other testing if needed to help diagnose the problem.
