This card shows three stylized cats posed front-facing in a neat row on an emerald green background dotted with small white shamrocks ☘️. In the middle sits a white cat with dark green spots, leaning slightly toward its companions as if enjoying being close. A deep forest green cat stands on the left and a ginger-orange cat on the right, and their gentle smiles and wide yellow eyes give the scene a friendly, affectionate feel 💚. Near the top, the word “HAPPY” appears in large white letters, centered above the cats. Just below that, “ST. CATTY’S DAY” is written in matching white type, also centered and easy to read. Lower down, the phrase “Little Brother” appears in smaller white text, tucked beneath the main greeting. The cats have smooth outlines with light shading, and the shamrock shapes repeat across the green field behind them.
