Ultra‑high‑definition 4K UHD photorealistic vertical portrait of two real house cats singing Happy Birthday to a lit cake on a wooden dining table. One ginger tabby and one black‑and‑white tuxedo cat, both in tiny party hats, positioned on either side of a frosted white layer cake with pastel sprinkles and a small cluster of lit rainbow candles; a retro chrome microphone on a mini stand angled up toward them. Capture them mid‑meow with expressive, comedic faces; one paw slightly raised like a conductor. Warm, cozy evening ambiance with string lights and a couple of balloons softly out of focus behind them; rich depth of field and creamy bokeh. Accurate lighting with gentle window or bounce fill plus candle glow rim‑lighting whiskers and icing; lifelike fur detail and frosting texture. Shot as if on a full‑frame DSLR, 50mm lens at f/1.8, ISO 400, 1/200s; tack‑sharp focus on cats and cake, natural background blur. Include a few pieces of floating confetti. Natural color grade (slightly warm), true‑to‑life proportions, no cartoon elements, no watermarks. Add a small, single‑line caption at the bottom center in clean white type with a soft shadow, unobtrusive and legible: “Happy Purrthday—duet you can eat.”
