I feed all my snakes f/t. And all of them but one start as live feeders. I've found that as long as the snakes hungry enough and the thawed rat or mouse is warm enough the snake will eat. A lot of people seem to have issues switching to f/t if you are thinking of doing it I'd thaw them out next to the snakes cage so they get the scent of the rat. This makes them more eager for food, and more likely to take a f/t rodent. Good luck
