#    Animals know things we don't. New York City's 1.5 million dogs
#    and 4 million cats live in two worlds: the ecosystem of instinct,
#    and the web of interaction with humans. Increasingly, eager pet
#    owners are exploring the possibility that our pets' thoughts
#    can be as accessible as our own--and that their knowledge can
#    form a bridge that transforms our lives.
