Yeah, you could try live again. See if that works. On the F/T try gutting it slightly for scent.

Our BP only eats F/T's and he's just a little guy so it's still on mice. Last night he ate snatched an F/T in the shortest time he ever has and I think it's because the mice was slightly gutted before I dangled it in front of him. He gave one flick of the tongue and it was about 3 seconds later and BAM!

The temps/humidity sound okay and there have been no changes to his habitat? My Burmese I had once went on a strike for about 4 or 5 months. It seems like these feeding strikes are actually more stressful on the owners than on the snakes!

Keep us posted and good luck!
