Lucas, I'm not an expert, but I've has my paulsoni for 8 years and have never been able to get her to take f/t rodents.
She'll take rodents, just not f/t. I've tried every trick in the book and she is the only snake I've every kept that I can't win her over.
When I first got her, she refused to take frogs, and would only eat feeder anoles. I am lucky enough to live in an area where western fence lizards are plentiful. I caught several groups of them, treated them for internal parasites and bred them for a number of years. She would eat those without fail.
After about three years I was able to get her on live rodents - first scented with lizards and then unscented. But she adamantly refuses to eat f/t, no matter how I scent them.
