A tiger cub with no mother in sight. A baby hippo. An abandoned meerkat pup. Without nurturing, these infants face certain death. Enter stories of the most unlikely cross-species relationships imaginable: a chimp bottle-feeding a tiger cub; a giant tortoise snuggling a baby hippo; a black crow parenting a meerkat. Aberrations of nature? Instincts gone awry? Does this kind of bonding form only when animals are removed from their natural environments? Or are they evidence of a broad array of emotions among animals? This film will look at these remarkable relationships firsthand, and through caregivers, biologists and animal behaviorists, explore what they suggest about the nature of animal emotions.
