This design shows an emerald green background with small white shamrocks floating around the layout, setting a festive St. Patrick’s Day scene ☘️. Down the center, the greeting “HAPPY ST. CATTY’S DAY” is stacked vertically in alternating black-and-white capital letters, making the pun the main focus. Near the bottom, three stylized cats sit close together as if posing for a friendly photo, their wide yellow eyes and tiny smiles giving them a sweet, affectionate look 💚. The left cat is dark green, the middle cat is white with green spots, and the right cat is an orange tabby, creating a cozy trio with contrasting colors. Simple black whiskers and rounded faces keep their expressions soft and approachable, like they’re sharing a quiet inside joke. Along the lower area, “Dear Sister” appears in white cursive lettering, with small shamrocks placed to either side. The flat shapes and strong outlines keep everything easy to read while the cats’ closeness adds a gentle, sisterly warmth. The final detail is the neat row of cats anchored at the bottom beneath the stacked title, framed by white shamrocks on the green field.
