Regal tabby cat in waistcoat by a cozy cottage fireplace

A regal tabby cat, depicted as if it were a character from a vintage children's storybook. The cat is shown wearing a tiny waistcoat and spectacles, sitting attentively by a fireplace in a cozy, illustrated cottage. The style is soft and whimsical, with gentle brushstrokes and a warm, inviting color palette, echoing the classic storybook illustrations of Beatrix Potter and Quentin Blake. The atmosphere is one of comforting nostalgia and gentle charm.
