It sounds as if your hamster is very sick. Usually when hamsters become so ill in such a short period of time there is not a good outcome. There could be several different things going on that have caused Comet to become ill so quickly. My best recommendation is to have Comet examined by a veterinarian to give him the best chance of recovery. I hope this helps. Best of luck.
