don't mean to be rude, but if you didn't want to go with lizards and toads then you shouldn't have gotten a w.c w.hognose.
if you only tried just a live pink you can try.
braining
scenting
lizard maker (I haven't used it, but it is supposed to work great)
putting snake and food item in a small container and leave for a few hours/overnight. You can use a live prey item seeing as it is only a mouse pink.
leaving the prey item in the cage with the snake over night.
what time of the day have you offered food? hognoses are more active during the morning and day time hours.
good luck. It's a real P.I.T.A when they decide they don't want to eat. if all else fails find out what they eat (specific toads or lizards) and start them on those, work your way up to scented, and then non scented then worry about getting him off of live food. Just an idea though.
