We are all familiar with the five senses that modern science acknowledges: seeing, hearing, feeling, tasting, and smelling. And there has long been speculation about a sixth sense. Having worked among animals all my life, I can assure you that this sixth sense exists, and that sense is more keenly developed in animals.
Sight is the reception of light energy by the eyes, carried to the brain by nerves, where it is interpreted. Hearing is the reception of air movement in the ears. Smell is conveyed by molecules in the air. I suspect that the sixth sense has something to do with magnetism, and it functions at distances too great for the other five senses to perceive.
Humans must determine whether an electric fence is functioning by relying on meters. Cattle and horses – normally easily contained by electric fence - are quickly able to discover a dead wire, and push right under it without fear. Livestock are also able to sense the minute change in the earth’s magnetic field caused by a gate that is left open a mile or more away.
We humans like to believe that our brains make us superior to animals, but critters make a fool of me on a regular basis.
