Quattro gatti pixel art sul tetto sotto un cielo azzurro brillante

Create a pixel art image of four domestic cats sitting in a row on a rooftop, viewed from behind. Include an orange tabby, a calico, a black tabby, and a white tabby with striped tails hanging down. Set during a sunny day with soft shadows, warm lighting, and vibrant colors. Use a limited palette (16bit style) with dithering for texture. The background features a blue sky with white clouds, an urban rooftop, a concrete wall, and plants in the foreground. Maintain a serene, slice-of-life with clean outlines and subtle shading.
