How big is a jumbo mouse?

do you have to breed for this quality or is it just as they get older, my breeder male is HUUGE ( ill weigh him tm.)

Is your male fat? Or actually large?

Here's a picture of a show mouse, compared to a large adult feeder mouse. Perhaps you coud call it jumbo. :P

he isnt fat, he is just larger then my other mice (same age same food) but of course my select feeder-breeder females weigh more sice theyre always pregnant.

i suppose i should start breeding for this quality that he has :) just larger mice!

i was just wondering at what size do you consider jumbo when selling f/t

Photos would be great. :)
