I generally have issues like that this time of the year, I typically just get a live mouse after week 3 if refusal and hope. But if that doesn't work I just make sure that the temps are good and that my boy isn't losing to much weight and hope he eats eventually. Just keep the live mouse around living in an old ten gallon terrarium I have laying around. If that isn't available and you can always just return your fuzzy then do that. It took my BP a long time to readily accepted f/t just keep on it and it will take to it.
