My Kenyan decided he was going to fast for about the past month and a half. We were still getting him out weekly and trying to feed him with the rest of the snakes, but he would just "cuddle" with his food with no striking or anything. He was constantly acting hungry (head slightly out of the substrate) but would never eat when I'd get him out. I was kinda scared to feed him in his encloosure b/c I didn't want him injesting any aspen....but through BP.net I have seen that a lot of people feed in the enclosure, so I gave it a try...he attacked the prey quickly and went to town eating it....so to everyone on here, I think that all the posts and opinions are great and they have definitely helped me with numerous problems I have encountered...thanks again to all.
