I thought most babies were eating frozen. Do they give them one live to introduce them to the concept of food and then switch to frozen right after?
I also read if you dethaw a mouse, and the snake refuses to eat, as long as the mouse as not been sitting around long it can be re-frozen for a second try.
And yeah it seems odd that you were told the snake has NEVER eaten. Even if that were true I am surprised they would admit it.
