Mrs. R. Lee assembles a rich tapestry of animal behavior, beginning with the primate order and progressing through bats, moles, hedgehogs, bears, badgers, weasels, otters, dogs, wolves, foxes, hyenas, and the great cat families. The author relies on authentic reports, personal observations, and accounts from trusted travellers to illustrate the sagacity, emotions, and complex social structures of the brute creation.
Throughout the pages, the boundary between instinct and reason is tested through concrete examples of animal ingenuity. Monkeys demonstrate remarkable tool use, elaborate social hierarchies, and deep emotional attachments, sometimes rivaling human complexity in their strategies and grief. Carnivores such as bears and badgers exhibit surprising playfulness, architectural skill in burrowing, and fierce maternal devotion that transcends mere survival.
The narrative pays special attention to the domestic dog, detailing instances of astonishing fidelity, mathematical comprehension, and problem-solving abilities that challenge traditional views of animal cognition. Accounts of wolves, foxes, and hyenas reveal the harsh realities of predation, cunning survival tactics, and the sometimes misunderstood scavengers of the wild.
The final sections focus on the great felines—lions, tigers, leopards, and panthers—exploring their majestic yet terrifying power in the wild. The author contrasts the distinct hunting styles and temperaments of these apex predators with their occasional docility when forming bonds with human companions.
By laying aside dry scientific classification in favor of direct observation, the work presents a living portrait of nature's diversity. The text concludes with a celebration of the Creator's wisdom as manifested in the varied instincts and dispositions of all creatures, leaving the ultimate definition of animal intellect as an open question for the reader to ponder.
