ピクセルアート風の緑のソファで眠る白い猫

create a pixel art image of a white cat sleeping on a green sofa with a small plant nearby, using a pastel color palette with limited shades (8-bit style). Keep the composition minimalist, focusing on close-up details like fur texture and pixel-perfect edges. Use dithering for subtle shading and maintain a low-resolution aesthetic with visible pixels. Avoid anti-aliasing for a crisp retro look.
