45 seconds，16:9 landscape，authentic smartphone slice-of-life Vlog。Throughout the entire video，use the same gray tabby cat from the first-frame reference image as the sole protagonist，a gray short-haired tabby cat，with gray-silver fur，natural dark gray tabby markings on the forehead and cheeks，a round cat face，a small nose，real whiskers，a relatively small、slightly rounded build，and realistic natural feline body proportions。Throughout the entire video，the cat's face shape、fur color、tabby pattern、eyes、and body size must remain completely consistent，it must not turn into an orange cat、white cat or any other cat，it must not become a humanoid cat，human palms must not appear，and it must always retain real cat paws、real cat legs、real fur and real feline body structure。This is a real cat that lives like an ordinary office worker living alone，it wakes up、washes its face、brushes its teeth、makes breakfast、eats breakfast、leaves for work、takes the elevator、uses a computer for office work、gets off work、buys groceries、goes home to make dinner、eats、watches TV and sleeps。Although it does human things，its body and way of moving always remain those of a real cat。When the cat moves from one place to another it must always keep all four paws on the ground，walking、trotting、running and jumping in a real cat's normal quadrupedal posture，no walking upright on two feet，no walking like a human，no standing on its hind legs for extended periods，no humanoid cat or anthropomorphic animal body。Only when it must manipulate objects，such as washing its face、brushing its teeth、cooking、or typing on a keyboard，may it briefly support its body on its hind legs and use its two real front paws to operate things，then immediately return to all fours after completing the action。When the cat walks，the movement of its shoulder blades、limbs、spine、tail and center of gravity must conform to real feline locomotion。The core visual logic is “this is first and foremost a real cat，it just happens to do human things”，rather than “a person with the appearance of a cat”。The entire video must look like an ordinary person casually using a phone to document the cat's real daily life Vlog，ordinary smartphone main-camera footage quality，realistic natural exposure，smartphone auto white balance，slight smartphone HDR，slight digital noise and video compression artifacts，slight realistic motion blur is allowed when the cat moves quickly，handheld tracking has very slight natural shake，slight framing drift and occasional imperfect subject tracking are allowed while following the cat's movement，some shots have realistic smartphone auto-exposure changes，slight natural overexposure is allowed near windows，slight underexposure is allowed in darker indoor areas，fur is clear but absolutely not oversharpened，preserving the imperfections of real smartphone video。Depth of field is naturally on the deeper side，the background environment remains normally visible，no professional cinema-camera look，no DSLR wide-aperture look，no strongly blurred background，no cinematic lenses，no cinematic color grading，no professional lighting，no rim lighting，no commercial pet portrait photography，no perfect composition，no CG look
