Mice sometimes carry it in their cheeks for storage,but rats tend to eat first then produce milk for any offspring they have.
I'm a florida trapper and ive seen some wierd stuff, when I comes to rats and mice.I'de hate to say they are a pain. I was doing a job at local town in fl outside of tampa. And it was a doggy day care by far the worst job. If, I might add that. Lol, so found food in nest by nest. They even started comin out in the daylight to feed. The dog food was in plastic container. Not a good idea, even the norway can chew threw steel,brick, concrete. Just get metal container for dog food before or after rodent problem.
With their paws :)
Only sometimes like if they get in your fridge or pantry they will take it and eat it at there hole
