Big Gunns couldn't have said it better himself. Although Big Gunns would NEVER use a "flowerpot" as a hide.Try and feed it a live Fuzzie....definitely not a pinky.
Do this right away. You might not want to wait a week to try and feed it since it's such a small snake that seems to be losing weight. The small tub and Aspen trick can work in one day, although it would be best to wait at least a couple.
