Regardless of your feelings towards animals, humans have lived and worked closely with them for centuries. From companion cats in ancient Egypt to messenger pigeons in the 19th century to the therapy and bomb-detection dogs in hospitals and military units today, we have long needed animals. We cared for animals because we have needed them for our survival.

Perhaps this is why humans still possess an instinct to protect the well-being of animals both domestic and wild. It is also possible that deep in our psyches, there is a simple and profound recognition of our similarities: that we all see, hear, touch, smell, eat, rest, play, mate, raise young, and die – shared experiences by all living beings on earth.
