[Thamnophis]

We have to forcefeed a lot of captive bred Candoia carinata paulsoni.
Most of the newborns do not eat the first year or so. Doesn´t matter what you try.
We start with mousetail-parts. Than whole mousetails, tham mouselegs or so. And later with pinkies.

Sometimes it is neccesary to forcefeed. Forcefeeding is normally meant to give them a quickstart or to save a life. After one or two forcefeedings the snake must start eating himself.
But we also have to accept that some snakes just do not want to eat.
