This card shows three friendly cats lined up on a lime-green background sprinkled with small white shamrocks ☘️. On the left, an emerald cat with darker clover spots looks forward with sunny yellow eyes and a small, satisfied smile, as if posing for someone it trusts. In the middle, a white cat with green clover markings and wide eyes leans into the group, giving the scene a cozy, close-together feel 💚. On the right, a warm orange cat with tiny pink cheeks wears a sweet expression, like it’s sharing a quiet joke with the others. Across the top, the phrase “HAPPY ST. CATTY’S DAY” sits in large letters, mixing deep green and orange so the words stand out against the green field. Near the bottom, “Great Grandpa” appears in a simple, friendly type style, centered under the cats. The overall look stays flat and graphic, with smooth outlines, solid fills, and shamrocks scattered around the trio.
