This design shows four rounded cartoon-style cats sitting close together on an earthy brown ledge along the bottom, their bodies angled just enough to suggest they’re keeping each other company. The background is a soft cream with gentle texture, and the lighting looks diffused, giving the scene a calm, cozy glow. Near the top, the words “Happy Birthday” appear in flowing dark lettering, centered above the group like a banner for the moment 🎉. A large solid-black cat with a curled tail sits beside a smaller calico with patches of black, white, and warm orange, and their slight lean toward each other adds a sweet, friendly closeness. Next is a medium ginger tabby with faint stripes, smiling softly as if sharing the celebration with the others 🎂. The fourth cat is black-and-white with a distinct face marking and rosy cheeks, rounding out the group with a gentle, welcoming look. Fine details like small whiskers, simple fur markings, and rounded paws keep the illustration soft and approachable against the creamy backdrop. The ledge runs straight across the bottom edge, with all four cats lined up shoulder to shoulder beneath the centered greeting text.
