Yes digital. Why not they are cheap.

But my origonal question was, is there like a normal size range foodfor a specific sized ball? like a 144g ball eats eats 20g food. Its hard to go to a store and imagine the size of the python compared to the mice on hand. However it is easy to weigh the mice and see how bigthey needto be.

Maybe i'm too pick and like numbers too much, the engineer in me coming out i guess
