Also I just remembered... there are those "snake sausages". You could use those, although I think a lot of people in the reptile community are unsure about them, just because they won't print the ingredients and are worried it leaves out the guts and the bones of the animal... both beneficial to the snake. From what I could find as far as nutritional adequecy goes, an adult mouse contains on average 19% protein and 9% fat, the sausages contain 16.5% protein and 13% fat... so guess it's up to you. I do know that Kathy Love had used it on their corns and they were perfectly happy with the product. Maybe something to research.
