Black Cat Sleeper Hat

This bold cartoon illustration features a sleeping black cat curled tightly into a cozy shape against a solid black background. The cat is outlined with a clean white stroke, giving it a sticker-like appearance. It has peaceful closed eyes, a tiny white nose, and delicate whiskers, while a set of playful white "Zzz" symbols floats above its head to indicate deep sleep, making it perfect for custom t-shirts.
