Next to the house where I grew up was a lot where people would through their trash.  At night, just about the time when I would get settled into bed, I could hear some strange noises outside my window.  Daisy my donkey, would start to get restless so I knew that another animal must be nearby.  Was it a stray dog, or a jackal?  Was it a leopard?  Was it a mongoose?  What was it?  It was definitely a hungry hyena!  They would come to sift through the trash and pick out any bits of garbage they may find.  Although they have a wierd shaped body, and not the most beautiful face, they sure do a good job at trash cleanup!  I suppose that is why they have the strongest jaw of any African animal.
