I feed most of my animals on a 5 day schedule. That being said some of my animals go off feed during the winter. This could be a natural method so they don't get overweight or natural turn off for breeding. Also you say your snake is getting large mice or rat pups and is a year old. A food item can be as big around as the snake is in the middle. If the mice or rat pups are smaller than this, you can feed larger items. Most of my animals start on rat pups/weanlings by 3-4 months old and 250-300 grams. There are some that will only take mice but they get multiple mice as they get larger. If your snake is on the smallish side, the prey you are giving is fine. I have a female from 04 that is still small no matter how often I feed her. I also have an 05 female that is already at 800 grams on the exact same feeding schedule. Hope this helps
