9 Y.O switching to rat pups?

[BLM94]

Hey all
I've had killer (thought it was a he since I bought it in 2003 until literally three days ago) since she was 6 inches long, now done growing at 4'10".
I've heard that rats hold more nutritional value than mice, and seeing as my girl is starting to get a bit older I figure she could use the extra nutrition.
My only question is if a rat pup has more value to an adult corn than an adult mouse. She eats 2 large mice every 10-14 days and has a girth slightly smaller than a golf ball, which IMO is a healthy build for her. Should I switch her to pups?
Appreciate any input,
Brendan

I keep my corns on mice. Give it a try and see though.

If you can switch her, why not? I can't think of any cons to the switch, and plenty of pros.
