This design shows three stylized cats sitting side by side on an electric green background, leaning slightly toward one another as if sharing a friendly, inside joke 💚. On the left is a dark emerald cat, in the middle a white cat with lime-green polka dots, and on the right a ginger cat that warms up the lineup with its sunny coloring. Their wide eyes and small smiles, paired with fine whiskers, give them a tender, companionable look, like they’re posing for a photo together. Across the top, the word “HAPPY” appears in dark green letters with a gold shadow, set in a chunky, 3D style that pops from the background. Just beneath it, “ST. CATTY’S DAY” is written in crisp white, centered above the cats and easy to read ☘️. Near the bottom, “STEP DAD” is printed in white and flanked by small four-leaf shamrocks that act like little brackets. A deeper green oval sits under their paws, grounding the trio like a simple stage.
