Grooming across the animal kingdom turns out to run on an odd mix of biology and chemistry, and this film catalogs the tools involved: combs, lotions, creams, and unguents that animals produce or apply to themselves and each other. Some serve courtship, making a body more attractive to a potential mate, while others exist purely for hygiene, keeping fur or feathers clean and functional. The film lingers on saliva as the simplest and most widespread example, showing animals licking their coats and scraping them with their teeth to work as both cleanser and brush. Alongside these everyday routines sit stranger substances, secretions and behaviors the narration frames as closer to cosmetics or spa treatments than anything utilitarian. There's no single species or habitat anchoring the film; it moves across examples to make its point that animal self-care is more varied and more deliberate than it looks at first glance.
