Not eating!? How soon after brumation to feed?!

[Pareeeee]

As I had mentioned in my other thread, Boaz was going through a one-month brumation to stimulate feeding.

Well, I think I made a mistake. I tried to feed him yesterday (the day after bringing him out of brumation) and he didn't eat. Well, this morning when taking him out of his feeding tub it actually looked like he tried to eat - some of the mouse's insides were hanging out it's bum like it had been squeezed, and the mouse looked maybe a bit darker and wetter. (maybe regurge?)

So maybe I misunderstood since NOWHERE on the internet could I find how soon to feed them after you bring them out.

Anyway, he hasn't eaten since October 22. How do I get him to eat!?!?!?

EDIT: I am feeding F/T, which is what he was used to eating.
