To soon to feed again?

Last tuesday I feed my 450g RTB a 125g rat. I didnt realize the rat was that big when I bought it as it was the first time that I had bought a rat before. Im going to go back to feeding two mice until he grows up some. Would 1 mouse be okay this week? Or should I not feed him at all for another week or two?

I'd wait at least 2 weeks after a very large meal. Better to wait until he/she goes to the bathroom though...
