Coloring Online: A cute kitten playing with a large ball of yarn in a cozy living room, surrounded by potted plants, cushions, books and scattered toys. Create a full-page children's coloring book illustration in clean black outlines, with thick smooth lines, large enclosed spaces, no shading or gray, and a white background. The scene must fill almost the entire vertical A4 page, with objects extending close to all four edges and minimal white margins.
