This card features three cartoon cats lined up across the middle on a lime green background dotted with tiny white shamrocks and soft green clovers ☘️. At the top, the phrase “HAPPY ST. CATTY’S DAY” arches in large green letters, with the “Y” in “HAPPY” colored orange to echo the ginger cat below 💚. The left cat is deep green with bright yellow eyes and a pink nose, looking sideways as if sharing a teasing glance with the others. In the center, a white cat sprinkled with green polka dots has small red accents and a gentle, friendly expression that makes the trio feel close-knit. On the right, the warm orange cat sits with an easy smile, balancing the group like a cheerful companion in the middle of a holiday photo. Near the bottom, the word “Sister” appears in flowing green lettering, tucked under the cats so it reads like a sweet tag beneath their paws. The overall look stays flat and graphic with simple shapes, while the shamrocks and clovers scatter evenly around the cats and text.
