They eat frogs as babies...they can be tricky to switch over, scenting techniques usually will work if you persist, but they often take a few pinks, then refuse to take them again and only want frogs...you can go back and forth like this for a while. I recently had a baby male that I got from Conway die on me because he began to refuse EVERYTHING. He was way to small to forcefeed, though I did try once. Thought I was gonna kill the guy so I stopped. I did get the female switched over onto f/t pinks, but it took several months of dedication to accomplish that. She's a monster rodent feeder now though.

Frogs can carry parasites that may harm your snake, so it's best to implement scenting techniques and get them switched pronto.
