Poor Matou! There are so many things that can cause a decreased appetite and weakness like certain viral infections, respiratory infections, bladder infections, kidney or liver disease, cancer and much more. If cats go a few days without eating, they can actually get worse because their liver will start to shut down and they get really dehydrated. Since it has alresdy been two days, i would strongly recommend to have your vet take a look at him. Your vet will be able to do a fecal, blood work and even X-rays if needed. Your vet will be able to get him on the proper meds and give him fluids if needed to help him feel better. You can try to entice him to eat with just plain chicken or tuna or different type of canned cat food. I hope this helps and he starts to feel better soon.
