PrincessBunny- Don't try to rush this snake to gain weight- you can do much more harm than good by feeding larger prey or more frequent meals than this snake's stomach is ready to handle.

Just feed regular meals at appropriate size & be very patient. Even when young (hatchling) snakes grow, they tend to look "thin" because every meal adds a bit of length instead of width, & then they defecate & look thin all over again. Weight gain happens very very slow in snakes- especially when you're waiting for it.

You've done a good thing- taking on this neglected & unwanted snake. Just be patient now....very very patient. Snakes survive much adversity in the wild, & with any luck, this one will thrive with your good care. Trust the process.
