So I offered the f/t hopper earlier tonight. Thawed in hot water and dryed/heated with hair dryer and prescented enclosure. Held the hopper with tongs at the entrance to the hide and did the mouse dance for a few minutes, no action. Removed the hide only to find the snake balled up with very opaque eyes, no way it could see anything. I continued to dance the mouse around the snake for a while, it looked like it was definately going to strike but never ended up doing it. Just seemed to be scared/irritated (understandably). Placed hide back over snake and left the mouse at the entrance to the hide few hours ago, if it is still there when I am heading to bed I will just remove it and trash it. Next time I figure I will just skip feeding during shed, unless I try live (which is all it has eaten) at least that way if it doesn't hit the prey it is not wasted garbage, just put the mouse back in its cage.
