This greeting card features a bright lime-green background that instantly signals St. Patrick’s Day energy 💚. Three cartoon cats line up across the lower middle: a deep emerald-green cat on the left, a white cat in the center covered in lime-green polka dots, and a tangerine-orange cat on the right. Their wide yellow eyes, pink noses, and small upturned mouths make them look like they’re sharing a friendly, in-on-the-joke glance with each other ☘️. Near the top, the word “HAPPY” sits in large white letters, spaced to stand out against the green. Beneath the cats, “ST. CATTY’S DAY” appears in smaller white text, with “STEP SISTER” set just below it in the same white lettering. White four-petaled shapes, like simple shamrock blooms, drift around the cats and the words across the green field. To share St. Patrick's Day sentiments, the scene is finished with crisp outlines and flat color fills that keep every cat and clover shape easy to spot.
