Switching Ball Python to f/t mice?

[vypr]

Another update for awhile -- the pre-killed mouse I left in his a hide across from another hide he was in didn't work out. He actually slept right next to the mouse in the same hide, curled up next to it.
I removed the mouse and I will not mess with the terrarium for another week.

EDIT: It's strange, not sure why but he is rubbing his nose against items in his terrarium... kind of like he is shedding. Strange.

EDIT2: He is really going at it, he is rubbing his nose on a branch, rock, and substrate.
The same way my Milk Snake does to shed.
Did the breeder give me a younger snake or something?
