A photorealistic vertical 9:16 mobile phone video featuring a cute silver tabby American Shorthair cat sitting upright on a blue-and-beige plaid bedsheet in a cozy bedroom. The cat faces the camera directly throughout the scene. The video begins with the cat using both front paws to gently pull its cheeks downward while sticking out its tongue, creating a silly and playful expression. Immediately afterward, the cat lowers its paws and suddenly opens its eyes extremely wide, giving the camera a hilariously shocked stare. Next, the cat raises both front paws beside its head and stretches its mouth into an exaggerated, wide toothy grin. The expression then smoothly transitions into a cheerful, happy smile with squinty eyes. Finally, the cat becomes calm and sweet while holding a bright red rose delicately in its right paw and gently presenting it toward the camera. The background includes a blue striped pillow on the left, a softly blurred green plush toy on the right, and beige curtains in the background. Warm, natural-looking indoor ambient lighting creates a cozy atmosphere. The camera remains completely static at eye level in a medium close-up composition, with shallow depth of field keeping the cat sharp while the background stays softly blurred. The footage should look like authentic viral pet content: highly realistic fur, natural-looking movements, adorable expressions, believable anatomy, smooth transitions between each facial expression, and a charming gentle ending pose. Absolutely no music, no song, no soundtrack, no background music, no background audio, and no added sound effects. The generated video must contain no audio whatsoever and should be completely silent.
