I once saw two birds sitting on a fence post watching a mouse eat an acorn. Several minutes had past before one of the birds decided to fly down and take the fruit of the oak tree from the unsuspecting mouse.
While watching his friend bully the little guy with big ears, the other bird was snatched up by a cat who was sitting on a tree branch watching him.
The odd part of this story is, three days later that same mouse was nibbling on another acorn while the cat waited patiently on the tree branch above.
