Vitamins for ball pythons is kinda odd to me....the only times I have ever heard of someone using vitamin type stuff for ball pythons is in cases of severe malnurishment and/or dehydration. But that is only to give them some nutrition and hydration quickly in order to rehabilitate the animal.

I (and many others) have also never been able to find the exact nutrition requirements for ball pythons. That kinda stuff usually requires some extensive research. From what has been observed for years, mice and rats provide all the needed nutrition for proper growth, breeding, and egg laying. IMO.... basically all that the vitamins are doing is going in one end and coming out the other.
