"Jaws that can crush a backbone become a tender conveyance as Sita totes a cub to a new den, a constant chore to safeguard her young from leopards, wild dogs, and other tigers. Hiding cubs well is critical, since she may be away hunting for 24 hours or more. Sita is living proof that this endangered species can flourish if only given enough room and enough prey."
