Designed with a lime-green background that fills the whole front, this St. Patrick’s Day cat scene feels bright and upbeat 💚. Three cartoon cats sit in a neat row at center: a deep forest-green cat on the left, a white cat with green spots in the middle, and a marmalade-orange cat on the right, leaning close like good friends posing for a photo. Each one has wide yellow eyes, tiny pink noses, and rosy cheek marks that make their expressions look soft and fond. Near the top, the word “HAPPY” is set in large letters, split between dark green and orange. Under the cats, “ST. CATTY’S DAY” appears in a prominent line, reading like the main headline of the card. Dark green shamrocks are scattered around the edges like confetti, adding a festive ☘️ touch. At the very bottom, “Sister in Law” is printed as a smaller line beneath the main phrase, with the shamrocks continuing to dot the border.
