I have this snake, Big Jake. He's a Florida King. He's humongous, and a teeny bit cranky. Like if he's blue, and you mess around in his viv, he's going to strike. I generally feed him in his feeding bin, like everyone else, but occasionally, he gets a little clean-up job that someone else didn't eat, and I just tong it to him in his viv. So lately he's been getting picky. He paces around in his feeding bin and won't eat. But if I hand him a mouse off the tongs when he's in his hide, he's like a moray eel. And I have noticed that now he is hyper-alert to any movement outside his viv, in hopes that it means food. And he makes me nervous about taking him out now, because he thinks every time I open his door, he's getting fed. Just like you always hear they do. And he's not like some little adult corn. So tonight he's out for relaxing time with me, not being fed, to refresh his memory that he's the pet. But I can see how you can cause a snake to associate you and your tong-like hands with food. When I feed everyone else, I put the food in the bin, and add the snake. Just my thoughts.
