I was told my first one ate f/t or live. Was giving it f/t cuz easier to store and less stinky smell. And she ate every time. Then came the other 2. Picky as heck. Will not even go around a f/t. Tried weekly for 6-7 times. They just run from it. It's almost like they could tell it was frozen, or something. l Finally just gave up, and feed them all live now. And they all ate every time. I guess they just prefer fresh over frozen.
