I've considered an experiment like this with either a vitamin supplement or a high quality ferret food. I think the first issue would be finding out the actual caloric/vitamin/mineral value that a mouse or rat has that gets absorbed by the snake. Then you would have to try to maybe double those numbers and see what your results are while tracking the number meticulously. The only true way to do this is through research and experimentation, but both of those things can put lives at risk. I would try it if I had a separate rack system and a couple hatchling normal balls that were aside from their diet, taken care of in the exact way. One would be the control and the other the dependent variable. Monthly and yearly weigh ins would be the standard to figure results. And a full case study to be published of course.
