When to move to the next size up

[rickyrivers]

Hello everyone!
I fed my corn today and after she was done eating I didn't notice a big lump on her belly. I'm making little slits on the mouse back before feeding it to my snake, so I can't really go with the 48hr rule to see if the lump went away during this time. ( You all know what I'm talking about ).
Unfortunately I don't have a digital scale, otherwise I would be following the Munson Plan... but because I don't know my cornsnake's weight I must ask you guys: Should I move to the next size up? In this case it would be weaned because she's eating hoppers. Can I feed 2 hoppers in one meal 'till I go out and buy some weaned mice?
My Cornsnake measures 25 inches long, and I was told she was born December 11, 2006 ( I'm not sure if this date is right, because I've seen corns bigger than her that are younger).

Thank you,
Ricky.

You don't need a scale or a plan, just stick with the general rule:

Food item should be no more than 1 1/2 times the width of the snake, at the widest part.

If there's no lump right after eating, that's a good sign it's time to move up. You can feed 2 at a time to use up your current supply.
