Use the provided start image as the exact visual reference. Preserve the same two prairie voles, their fur colors, proportions and realistic appearance throughout the entire video. Create an 8-second vertical 9:16 intimate wildlife documentary sequence about social grooming between two prairie voles. 0–2.5 seconds: Start exactly from the provided extreme macro close-up. One prairie vole gently and repeatedly grooms the fur around the head, forehead and neck of the other vole with small natural licking movements. The receiving vole remains still and slightly tense at first, eyes partially open. Make the grooming biologically natural and subtle, never human-like or overly affectionate. 2.5–5.5 seconds: The camera very slowly pulls back, revealing both prairie voles sitting close together. The grooming continues naturally. The receiving vole gradually becomes visibly calmer: its posture softens, body tension decreases, eyes become more relaxed. The animals remain physically close. 5.5–8 seconds: The grooming gradually slows and stops. The two prairie voles remain quietly pressed close beside each other. One gently rests against the other. Hold this peaceful final composition for the last second. Their behavior should look like authentic animal social contact, not a romantic or anthropomorphic embrace. Naturalistic high-end wildlife documentary cinematography, extremely realistic fur and anatomy, shallow depth of field, soft warm natural light, muted earthy background, subtle slow camera movement. No humans, no laboratory, no cage, no text, no graphics, no hearts, no exaggerated facial expressions, no anthropomorphic gestures. Audio: No music, no soundtrack, no voice-over. Only intimate natural sounds: very subtle grooming sounds, tiny movements in the fur, quiet breathing and soft natural ambient room or habitat sound. No cinematic sound effects.
