Designed with soft, muted pastels, this Birthday card shows a cheerful group of stylized cats gathering for a sweet celebration 🎂. A grainy peach background is sprinkled with tiny hearts and starburst shapes, setting a gentle, affectionate scene that feels like close friends leaning in together. Near the top, two gray-striped cats float among balloons—one holds a large spotted green balloon, while the other steadies two balloons in deep green and warm coral, their faces turned toward each other with a tender, companionable look. Centered between them sits a two-tier cake with pink frosting and three small candles, and a tiny mouse peeks out beside the cake as if joining the party quietly. Along the bottom, three cats in tawny and white tones lift a string of multicolored triangular pennants, their rosy cheeks and soft smiles suggesting shared closeness 🎉. The birthday greeting text is placed prominently across the design in a simple, easy-to-read style, colored to coordinate with the pinks and greens. One cat wears a striped party hat, and the pennant string arcs across the lower half in alternating shades like coral, teal, and yellow.
