A lot of snakes eat other snakes as prey. King snakes being one's who are very cannibalistic, which is confusing me because the snake in the video happens to be a Western Hognose. The only reason I can think of is that snake must've mistaken it's tail as prey. When snakes start eating something it is very hard for them to stop so they usually keep trying to swallow whatever they started on. The snake could be hungry, but I doubt it, snakes can go months without food and be fine. Poor snake.
