Create a breathtaking, high-definition illustration of an orange tabby cat with a fluffy coat, sitting gracefully and looking upwards with a serene expression. Surround the cat with a burst of vibrant, swirling colors transitioning from warm oranges and pinks to cool purples and blues, creating a magical, ethereal atmosphere. Add numerous butterflies in shades of blue, purple, and pink, fluttering around the cat, enhancing the dreamy and whimsical feel. Ensure the background is soft and abstract, with a blend of colors that complement the cat and butterflies, adding depth and a sense of tranquility to the scene.
