Thus far, my first feeding has been a failure. The BP doesn't appear to be the slightest bit interested in the hopper. Maybe it is due to the fact that the mouse was almost dead when we decided to do the feeding, and therefore wasn't very appealing. I was surprised that the mouse only lasted a few hours in the box from the store...I had expected it to live long enough to get to the feeding. I have left the snake alone, with the mouse, in his feeding bin to see if he takes it without any disturbances. If not, I guess I'll try again next week.
