Reptile Cave

We took a trip to some more caves this weekend.  In one of the caves they had a reptile zoo.  It was a little scary.  In the water jug shown below, there was actually a very angry cobra, head raised and flat.  The top of the jug was covered with only some mesh with a rubber band holding it on.  What was more scary was the empty cages we saw occasionally...where were they?
