There are many reasons why so many of us choose to share our lives with a pet--it's the perfect antidote for loneliness, providing an endless supply of smiles and the certainty of unwavering companionship, and many of us have seen the way a pet can make a family feel whole.

When the cure for insecurity and meaningful conversation is to slap a cell phone against your ear, hide within your iPod, or tap out a cryptic instant message, is it any wonder that we find comfort and solace in hairy, furry, and scaly companions?

Over the years I've come to appreciate how animals enter our lives prepared to teach and far from being burdened by an inability to speak they have many different ways to communicate. It is up to us to listen more than hear, to look into more than past.

Sometimes nature can take its course and shove it. Our commitment to protecting our cat or dog is life-long and sadly, sometimes, that includes protection from discomfort and pain, even if, in the vet's opinion, this means euthanasia.

Perhaps the greatest gift an animal has to offer is a permanent reminder of who we really are.
