Is my baby ball python going to starve himself??!

[AbsoluteApril]

Ive heard of putting them in a paper bag with the feeder and seeing if they eat. Should I try that right now or should I just leave the mice in all night?

Just to touch on this specific point, that's a trick that I've used and can work for corn snakes. I have never heard that used for ball pythons and would NOT recommend it.

I also agree that something might be off a tad, a hiding ball python is normally a happy ball python and I'd be concerned he's in the vines and not a hide. I'd put a hide right below or under the vines (without anything wadded paper in it).
The link Deborah posted is great and highly recommended to follow.
