This card shows an emerald green background with three stylized cats sitting side by side like close friends posing for a photo 💚. On the left is a deep forest green cat with a dark-tipped tail, in the middle a white cat covered in bright green polka dots, and on the right a sunny orange cat with a darker striped tail. They face forward with wide yellow eyes, tiny pink noses, and fine black whiskers, their small smiles giving the scene a gentle, affectionate feel. Near the top, “HAPPY” appears in cut-paper-style letters in orange, white, and darker green, spaced across the upper area. Small white shamrocks float around the cats like confetti ☘️. Beneath the trio, the line “ST. CATTY’S DAY, Our Son” is set in white lettering and centered under them. The cats’ simple shapes and tidy row keep the focus on their friendly expressions against the green field dotted with petite shamrocks.
