Because predators tend to eat the weakest of a species, they keep the remaining population strong. Without predators, herds become weak and disabled. In contrast, when humans hunt animals for trophies, they kill the strongest of the species, thereby weakening the herd.

Wesley taught me the Way of the Owl. In the human world your value as a person is often intrinsically linked to your wealth or most recent accomplishment. But all the accoutrements of the world were stripped away from me when I got sick. Welsey made me realize that if all I had to give was love, that was enough. I didn’t need money, status, accomplishment, glamour or many of the empty things we so value.

IN THE WILD, the father owl hunts relentlessly. He has to provide approximately six mice per baby per night. The usual brood is five babies. The father also has to feed his mate, who never leaves the nest and eats about three mice per day. And he must feed himself about four mice a day. This adds up to some thirty-seven full-grown mice every night during nesting season.

It was a lot like working at Hogwarts, except that, instead of receiving letters from our owls, we would find coughed-up owl pellets in our coffee mugs.

Wesley was always outraged when he woke himself up with a screech in his sleep, and he blamed me. He would whip around to face me with an intense librarian’s stare as if I had broken a cardinal rule.

To that which you tame, you owe your life.

Wesley went everywhere with me from then on. I even wrapped him in baby blankets and held him in my arms while grocery shopping, to keep him warm during the first cold winter. Occasionally someone would ask to see "the baby," and when I opened the blanket, would leap back shrieking, "What is that?! A dinosaur?" Apparently, the world is full of educated adults with mortgages and stock portfolios who think people are walking around grocery stores with dinosaurs in their arms.
