Create a pixel art image of a grumpy tabby cat in a police mugshot style. The cat stands against a height measurement background (50, 55, 60, 65) with a stern, half-eyed expression. It holds a black sign with white uppercase text: "I HATE PEOPLE." Use a limited 8-bit color palette with high contrast for a retro feel. Emphasize pixel-perfect shading and dithering for texture. Keep the composition simple, with bold outlines and minimal details to match classic pixel art aesthetics. The scene should be humorous, playing on the antisocial cat stereotype. Avoid gradients or smooth edges—maintain a blocky, low-res look.
