“You can judge a man’s true character by the way he treats his fellow animals.”
― Paul McCartney

“Animals don’t hate, and we’re supposed to be better than them.”
― Elvis Presley

“If having a soul means being able to feel love and loyalty and gratitude, then animals are better off than a lot of humans.”
― James Herriot, All Creatures Great and Small

The animal kingdom is filled with almost an infinite variety of creatures. Scientists discover new species and subspecies every year. Each one is a wonder unto itself and one could labor for years to uncover its secrets. It is an unfortunate fact that the closest that most of us get to wildlife is through bars at the zoo. Our urban lifestyle has the effect of cutting us off from the glorious world of the animal kingdom. Every animal has a lesson to teach us that we are not hearing. We may think that we have evolved away from contact with the animal kingdom, the question is, at what cost?
