usually when a snake eats and you cant see a buldge in the stomach i usually move up in 2s or up to the next level. like pinky 2 pinkies, peach fuzzy, regular fuzzy, 2 fuzzies, hopper, 2 hoppers, weanling, etc. just until yo can see a lil bulge in the tummy. nothing too big now! b/c that can make him/her throw up. just slowly. so i'd try 1 large pinky and a small pinky and see if that leaves a lump. if not. try another small one.
