Yes it's possible. Mine took f/t twice for me but never really seemed very into it, then she just stopped. I tried all the tricks but she lost enough weight that it was getting worrisome so she had to start eating live. She still won't take f/t.
So, a live feeder might kickstart a feeding response, but if that's something you'd rather avoid it doesn't have to be on the table until she loses a dangerous amount of weight.
