do not EVER give the prune and mineral oil again, you could do some serious damage.... mike gave you some sound advice, why didnt you take it? Apricots will work just as well as prunes and they actually LIKE IT! You are givoing your poor gecko excess stress. We have kept and bred cresteds and do know what we are doing in husbandry and so on, so please do not ignore Mike or I.... ok? Please leave your gecko alone for a while, make sure you have no substrate in the cage to prevent future accidents.
