My male mouse has become rather fat. I know he is a male so that rules out pregnancy. What else could it be??

He is DEFINATELY male. He did however eat one of my female mice and since then he was a bit on the podgy side. But looking at him tonight he is very fat. He has rolls under his belly! Before I take him to a vet I thought maybe someone might have some helpful info for me. Thanks.
Answers:
He ate a female mouse? I assume you mean after she died? This is in fact quite normal, it's a result of their instinct to clean up the nest as quickly as possible, to avoid the smell of "dead mouse" from attracting predators.
What was a female doing in with your male mouse, though? Or were you trying to breed them? (In case you were/are: don't. You should only breed 100% healthy animals. This guy might have hereditary obesity.)
As for the obesity... it could be just that. Which colour does his coat have? (Some yellow/orange coat colours are caused by genes that also make the mouse prone to developing obesity.) Other possible cause: what does his diet consist of? Nuts, for example, are fattening. So don't give him too many of those.
Another possible cause are tumours (one or multiple), but this is less likely if he has an "overall fat" shape (tumour => big lump in one location).
As for should you be worried: I'd say yes. Being slightly on the chubby side isn't too bad, because they lose weight very quickly if they fall ill, so it can come in handy if they have a bit too much of it. "Rolls under his belly" sounds like your little guy is seriously overweight, though. That is definitely not healthy and makes him prone to all sorts of cardiovascular (e.g. heart) problems; and also to "bumblefoot" (ulcerative pododermatitis) because of the increased pressure on his foot soles. Bumblefoot can be incredibly difficult to cure.
It sounds like you need to put this guy on a diet.
Also: what type of cage is this guy in, does he have a wheel?
