Well, I tried out f/t on all the snakes. Akina and Shane, two of my normal females refused but Akina is in deep shed so I'm not surprised. All of the other snakes struck and constricted. Now just got to see if they will eat them. I am very happy with this! Now I don't have to worry about feeding live. Now I just have 2 to convert to f/t. (not including the hatchling)
