I got a kingsnake back in april, about six months ago. I was told when I got him that he was "at least" a year old, but he's already over 5 feet long. He used the best eater, he ate about 3 mice every two weeks, Sometimes even 2 mice once a week. But he hasn't eaten in at least 6 weeks, maybe more. His lighting and heating set-up has not been changed much, except I switched him from a red heat lamp to a ceramic heat emitter.
