Re: switching to f/t
Like everyone else has already stated, the process of switching them over can take a bit of patience sometimes. In all the years that I've been keeping snakes, I can only remember one individual that absolutely defied any attempt at switching over to frozen/thawed prey -- a male eastern Russel's viper (Daboia siamensis) that would have rather starved itself to death than to swallow its pride and a thawed rodent along with it.
Aside from that spectacularly stubborn individual, every other snake that I've encountered in private or professional collections has (eventually) taken prekilled prey.
