Create a cute, small cat accessory for a Roblox avatar's head. The cat should have big eyes, a tiny pink nose, and soft, fluffy fur in pastel colors like white or light gray. Its ears should be perky, and it should have a playful, relaxed pose with paws tucked in. Add a small curled tail for extra cuteness. The item should fit comfortably on the character's head, with a whimsical and charming design that suits all Roblox avatars.
