"A fluffy, chubby, and adorable black cat with round yellow eyes and round black pupils, with its hands behind its back, stands proudly sideways with a confident and happy smile. The cat's thick, soft fur is rich in detail, and its fluffy silhouette is accentuated by soft edge lighting. The expression is cheerful and playful, the eyes sparkle with joy, and the corners of the mouth are curved into a lovely, satisfied smile, which must be gently curved upward. The background is a simple, clean, light beige gradient that creates a soft and minimalist atmosphere that is entirely cat-centric. Ultra-realistic 3D cinematic lighting, shallow depth of field, soft bokeh, accentuate the cat's pride and happy mood.
