I agree that wild garters raid rodent nests from time to time and it's part of their natural diet, but just as a disclaimer (since the OP doesn't seem to have any snake experience) they will eat a great deal of non-healthy and non-food items if they are excited and hungry. If I'm in the middle of a feeding and they expect another pinkie, I could probably drop a lego block in there and they'd try to eat it lol.
