A. It sounds like he is dehydrated and severely lethargic. These symptoms are very general though and I couldn't point on a cause just based on these.
I recommend to take him to the vet today as it sounds like an emergency, he will need at least a blood test to try and identify the problem. If you are lucky it will be only an infection but bear in mind it might be something more serious.
