There is a cycle of love and death that shapes the lives of those who choose to travel in the company of animals. It is a cycle unlike any other. To those who have never lived through its turnings or walked its rocky path, our willingness to give our hearts with the full knowledge that they will be broken is incomprehensible. Only we know how small a price we pay for what we receive. Our grief, no matter how powerful it may be, is an insufficient measure of the joy we have been given.
