they are "almost" the same, I think one is 23 days, and one is 21 days, but both can go up to 24 days before giving birth. And they are both weaned at 3 wks old. Though, not sure when mice are sexually mature, but rats sexually mature at 5wks old.
Nutritionaly rats are better (unless you have a really small snake that needs mice). Stink less (so I've heard), and are just smarter animals than mice.
