i agree with the 1 week no handling no feeding. BUT you can try on the first attempt to switch prey types. With every animal i've ever gotten that has fed live its entire life, i switched to F/T the first feeding i had it. Why? Because its easy for me. If there was a refusal, i'd give the animal a week and in that time get it its preferred prey item. If its live, i'll pick it up a mouse. The absolute KEY to this though is PRE SCENTING. trying to switch a live feeder to F/T feeder without prescenting is not a good idea.

^ the above is my personal experience
