A fully colored cartoon illustration of a grumpy black cat with piercing yellow eyes wearing a festive red and white Santa hat, sitting defiantly with one paw raised mid-swipe knocking over a decorated Christmas tree. The cat has an unapologetic smirk expression, prominent whiskers, and fluffy black fur with subtle depth shading. Ornaments and tinsel are scattered around the base, with a toppled star ornament near its paw. The text 'On the Naughty List' appears above in playful handwritten script font, while 'Worth Every Moment' curves below in matching casual script style. Rich color saturation features the red Santa hat with white fur trim detail, multicolored ornaments (red, gold, green, blue), and glossy highlights on each decoration. The overall composition is centered and vertically oriented with the cat as the focal point between text elements. The design is print-ready, fully isolated on a white background with no shadows or textures, fully contained within canvas boundaries with no cut-off elements and proper margins around all elements, and intended for use in t-shirt printing. | PODspy AI Design
