[Noinch]

Hi i have a new crested gecko and up till now ( around a week) i have found all the info i need on the internet ie: food, vivarium, eating habits, but twice when i have got him out he has gone to pooh and is hell bent on eating it, but he poohs all the time and he doesnt eat it, but this pooh is like clear with red stuff in it. at first i thought he was throwing his tail. when i get him out he hardly moves. but when he does this its obvious he HAS to lick it up. What is this stuff? I dont think its pooh and i can find nothing to help me on the internet. Please help.
