Without fail, he always signed off on these letters with love and he always included Whiskey and Bess in the list of individuals sending this love my way. At the time it made me laugh, it made me embarrassed, but as soon as I softened, as soon as I matured back into his son, I came to appreciate what he was saying -- an endearing and magnanimous reminder of how family will always be the sum of its individual members, be they human or animal.

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.

Our pets are the kids who never leave home, and that's absolutely fine by us because these kids don't ask for the keys to the car, don't turn up drunk at two in the morning, and don't complain if you turn their bedroom into a home gym. Their presence in times of upheaval and transition acts as a touchstone, a reminder of normalcy, of comfort, and the certainty of a love that can get you through.
