This card shows three stylized cats sitting side by side on an emerald green background that shifts in tone, their wide eyes and soft pink cheeks giving them a sweet, friendly look 💚. The left cat is deep green with lighter green polka dots, the middle cat is white with matching green dots, and the right cat is solid orange, and the trio feels like a close little group leaning into the holiday together. Near the top, the word “HAPPY” sits centered in thick, rounded letters, colored with a mix of white, dark green, and orange like the Irish flag. The cats’ simple shapes and gentle shading add a cozy, affectionate mood, like they’re posing for someone they care about. Along the bottom, “ST. CATTYS DAY” is written in large white lettering, with small white shamrocks on either side ☘️. Just beneath that, “BROTHER IN LAW” appears in smaller text, neatly aligned and easy to spot. The background stays uncluttered so the cats and lettering stand out, and the shamrocks look like small white cutouts against the green field. The final details include the white shamrocks flanking the bottom line and the soft blush on each cat’s cheeks.
