On the front of the card three stylized, front-facing cats sit in a neat row on an emerald green background, their wide smiles and bright yellow eyes giving each other a friendly, close-knit look 💚. A deep green cat is on the left, a white cat with dark green spots sits in the center, and an orange cat is on the right, creating a tidy color flow across the page. Their simple shapes and small whisker details keep the scene easy to read while still showing personality. At the top, the word “HAPPY” appears in large all-caps letters, with colors alternating between black, orange, and cream. Near the lower middle, “ST. CATTY’S DAY” is set in crisp white capital letters, standing out sharply against the green. A smaller “Dear Brother” appears in white, placed below the main title line as a gentle, affectionate note between the sender and the recipient ☘️. White asterisks and small black shamrocks are scattered around the cats, filling the space like confetti across the background.
