I haven't got a scale yet and i had gotten him rat pups to try it but he was having a little trouble eating it like it was to big for him... would it help y'all if i posted a pic of him? and i was told to offer him food every 4 days and he does take it each time... as for feeding him three hoppers i was told if he takes the first on or second one really quick to give him a third one but not to pass three in one sitting.
