Create a risograph-inspired poster featuring playful and adorable cats and kittens as the central subject. The design should capture the unique, grainy texture and vibrant color layering that is iconic to the risograph printing style. Use bold, contrasting colors like neon pinks, blues, and greens to bring out the quirky charm of the cats and kittens, playing with overlapping patterns and slight misalignments for a retro yet modern feel.Incorporate elements like stylized whiskers, abstract fur textures, and minimalist backgrounds to highlight the risograph's artistic imperfections. The overall design should feel handmade yet bold, with the cats and kittens interacting in playful and imaginative ways, making the visual both captivating and delightfully fun.
