Sounds to me like your f/t isn't warm enough. These guys strike at heat, and if you are warmer than the food, then you ARE the food.

In feeding multiple prey items, I always wait until the first is completely swallowed and the snake is looking for more { all but a very few will do this } then I heat the second and offer it. Usually there is little trouble getting them to strike and coil a second item if they are hungry.
