Answer
OK, no more force feeding for at least 1 month.  I want you to set up the cage so that he has a hide box with WET spagnum moss in the bottom of it (even a little standing water would be ok).  Then make sure the air temp in the cage is at least 85F.  Then don't touch him for 7 days.  Once all that is done, place the prey right in front of the hide box and watch.  If he doesn't take it within 5 minutes remove it and try again in 8-12 hours.  If live doesn't work try dead (again right in front of the hide box).  My bloods NEVER came out of their hides except to poop here and there.  Once it has fed twice you may start handling it again.  If it hasn't fed in one month force it once and start over.
