Years ago I was afield with my wife. A tractor was plowing back a three or fouir year growth of unharvisted rye in a 15 acre field. As we stood, waiting for the tractor to pass, we say two very happy foxes following behind the plow. As mice were plowed up, they took turns grabbing and eating them almost smiling in their delight at this plenty. They got within 10 feet of us and we moved. The Foxes were shocked! They damned near had heart attacks, and ran like small rockets into the woods. Carol and I laughed, and entered the woods near where they did, and looked around for a den. There was "sign" so we left.
Animals are great to watch, they do have "trains of thought", and if you don't forget what they are, animals, it is very transparent.
