The little western hognose snake I picked up at the show 8 MONTHS ago finally ate of his own will. I had been pinky pumping him for the past 2 months and he finally ate a pinkie that i offered him. Whenever I would offer him a pinky he would do his "I'm a big, bad puff adder/rattlesnake" routine without taking the pinky then try to get away.
I'm very relieved that he's eating on his own now.
