Hand-drawn image of a cute cat wearing a Santa hat, sleeping by a simple fireplace. The fireplace should have minimal Christmas details like a hanging stocking or a small wreath. The design must have a thick, bold outline with no shading, and the cat's body should be curled up peacefully near the base of the fireplace. The background is clear and uncluttered, with only a few simple holiday touches. The overall style should be simple, cozy, and easy to color.
